Well slotted filter

Application

1. Beefing up the walls of vertical, inclined and horizontal wells drilled in incompetent reservoirs: • in open side holes of the wells • in the zone of the well productive bed2. Filtration of the product being extracted from extraneous inclusions, sloughing of sand and penetration of mechanical impurities into the well in operation.

The Well Slotted Filter is used to filter the product being extracted from foreign inclusions and penetration of mechanical impurities.The fluid being delivered to the suction pipe of the pump from the well is cleaned from mechanical particles by passing through a filtering element made from V-shaped profile of stainless steel, grade AISI 304, AISI 316, which helically, with a definite pitch, is wrapped around reference cells to provide a rigid screen with longitudinal slots with a strictly definite gap. Sharp edges create an arch (sand bridge) over certain areas of the slot and permeability over these areas is retained. At customer’s request, perforated holes are blanked off with plugs from aluminum, magnesium or polyamide alloy.To produce filters, casing strings and tubing strings of different type sizes are used, which can be complete with centralizers.

Advantages

1. Stable throughput capacity during the period of full operation cycle;2. Stable operation of downhole pumping equipment thanks to greater filtration surface;3. Low clogging level of the filter element due to unsteady position of mechanical particles on the filtering surface and the clean surface of the V-shaped filter;4. High strength of the structure in axial and radial direction due to increase in the number of reference cells;5. High corrosive resistance and resistance to aggressive impact of acid and alkali media.

Using a reservoir pressure maintenance system our experienced personnel within the shortest possible period of time will carry out dewatering of pure water-storage reservoirs, fluid waste receivers (industrial wastewater receivers, oxidation ponds, rainfall receivers, lagoons, holding-evaporation ponds), solid waste receivers (tailing dumps, sludge dumps, dung dumps, domestic solid waste dumps) and fire water ponds of any size and configuration constructed in pervious soils under service conditions from -45 to +50°C.

Application

• In oil and gas industry when constructing, repairing and maintaining of product-collection system during drilling and repairing wells.• When constructing impermeable membrane liners for industrial wastewater receivers, oxidation ponds, rainfall receivers, solid waste receivers.

Concerning waterproof materials

Basic material for impermeable screens is a polyethylene film defined in the standard GOST 10354-82 produced from the high-density polyethylene with addition of heat and light stabilizers. That’s why the screen material is characterized by high waterproof and mechanical properties combining with non-reactivity to acids and alkali. If necessary the impermeable screen can be produced single-skin or double-skin with the layer thickness of 0,2–0,3 mm.

Depending on specific construction conditions: type of soil, presence of grit particles in the soil, protective layer deposition technology we use the laminated waterproof screen which fosters far long-term function retention of the impermeable screen. An original screen deposition technology is used to eliminate the appearance of additional pulling stresses from soil distortion in the film element.

Application

Casing strings series OTV produced in accordance with Technical Requirements TU 1327-009-20970456-2015 are used to case oil wells, gas wells of complicated profile and the wells in which there moves the heat transfer medium at a temperature of up to 250 oC.

The uniqueness of the design consists in the following: sealing of the threaded joint due to interference fit contact at C point of the toroidal seal band of the nipple with the female cone in the collar.

Technical specifications

Advantages of threaded Joints:

1. Improving the quality of pipe assembly on the well by means of free entry without rotating the nipple into the collar at a depth of 12 threads which reduces the probability of the threads getting cocked and ensures distribution of the load from the weight of the pipe being screwed on over several mutually contacting threads.

2. Increasing the axial load for extension and compression in the threaded joint F-6,35, virtually to the load which the casing string body withstands. The load increases as result of redistributing it over the threads of incomplete profile in area g, the metal cross section area under which increases;

3. Equal distribution of axial load over the threads as a result of gradually increasing the thread depth from the indicating band (5) to the main plane;4. Facilitating visual control of thread screwing completion by comparing the collar end with the beginning of the wide circular band (5); 5. Increasing reliability of the casing string when lowering it into severely curved wells by optimizing gaps near the threads as well as the toroidal and taper design of threaded joint

Application

Casing strings TМC-SRV1 produced per Technical Requirements TU 1308-100-78691656-2015 by TMC-Drilling Service LLC are used to case oil and gas wells of complicated profile.

Advantages

Sealed geometrical interface of the threaded profile and two abutment elements. Design Features of the Threaded Joint:

1. On the pipe, threads are cut per GOST equivalents and, in addition, a sealing abutment element is installed which ensures joint sealed interface between the threaded profile and two abutment elements (ridge on the pipe and the bore in the collar) “metal-to-metal”.

2. In the entire interface of the threaded profile and sealing abutment elements, there is no gap between the outside surface of the seal on the pipe nipple and in the collar bore. Geometry is sealed on the geometrical dimensions of the thread profile angle interface, on the nipple end and in the bore , i.e. on the collar end “metal-to-metal” as well as on the diameters of the sealing elements. Existence of two turns of the incomplete thread profile on the sealing diametrical surface of the pipe nipple sealing element, which serves as a damper, when the joint operates, is a distinguishing feature of the geometry and a competitive advantage of the Management Company TMC Group LLC. After triple screwing together and unscrewing of the joint, the turns of the incomplete profile disappear from the seal surface.

3. The joint allows considerable increase in the make-up torques and in the bearing capacity of the threaded joint as well as increases reliability when combined loads act cumulatively in the form of extension, compression and inner hydraulic pressure.

High strength highly sealed casing string TMC-SRV2Application

Casing strings TMC-SRV2 are used to extract high viscosity oil by steam assisted gravity drainage (SAGD) which presupposes drilling two parallel horizontal wells to inject steam into the formation and cracking viscous oil as well as for oil extraction.

Unique design

This joint is characterized by high compression strength, tensile strength, bending strength and corresponds to the CAL IV requirements level which confirms that it can be used in the most severe conditions of oil production. Another special feature of the threaded joint TMC-SRV2 is its capability of being assembled on the inclined support of the drilling rig.

Advantages of the threaded Joint “DOMINANT”

• On the pipe, the thread profile is cut and, in addition, a sealing abutment element is made which ensures joint geometrical interface of the threaded profile and the sealing unit on two toroidal surfaces “metal-to-metal”.

• In the entire interface of the threaded profile and sealing abutment elements, there is no gap between the outside surface of the seal on the pipe nipple and in the collar bore. Geometry is sealed on the geometrical dimensions of the threaded profile angle interface, the nipple end and the toroidal seal.

• The joint allows considerable increase in the make-up torques and in the bearing capacity of the threaded joint as well as increases reliability when combined loads act cumulatively in the form of extension, compression and inner hydraulic pressure.

• Torque values are different from those shown in the table of minimum, optimum and maximum Mcr. For casing strings 245*8.9mm – Mcr = 42kN.

Application:

The coupling joint of casing strings with buttress profile thread is designed to construct and operate vertical wells of oil, gas and gas condensate fields. The BUTTRESS joint combines the functions of a “lead screw” and the joint hydraulic seal which ensures good reliability of the joint compared to equivalents.

Advantages:

Acceptance of increased axial loads in one direction, the thread form allows reduction in friction coefficient and doubles the resistance to displacement for reasons of increase in profile.

Casing string with increased operating reliability and BUTTRESS profile

Design features of the thread joint:

1. The design feature of the casing strings with BUTTRESS threads is high resistance of the threaded joint to tensile loads. The profile of the BUTTRESS threads looks like a trapezoid with unequal sides (pitch 5.08 mm, cone 1:16). Embedment side which accepts load at the time of fitting the pipe joint into the coupling part, operating by compression, is made at an angle of 10 oC. That ensures easy fitting of the pipe into the coupling and reduces thread sticking.

2. Three degree deviation of the profile support side would reduce the risk of the pipe threads coming out of the mating with the coupling thread when it is stretched hard or bent.

3. Seal is ensured by pressure of the thread sealant in the design gaps of the threaded joint profile. If specified by user, it is permissible to produce a threaded joint with fluoroplastic sealing ring in the coupling.

4. Quality control of screwing the pipes together by machine is made by position of the coupling end with reference to the triangle sign shown on the pipe. Correctly assembled joint is considered to be the following one: when the coupling end is one turn short of reaching the triangle sign base.

Casing string with increased operating reliability and OTTM profile (GOST 632-80)Application:

The coupling joint of casing strings with buttress profile thread is designed to construct and operate vertical wells of oil, gas and gas condensate fields.

Design features of the thread joint:

1. The design feature of the casing strings with OTTM threads is high resistance of the threaded joint to tensile loads. The profile of the OTTM threads looks like a trapezoid with unequal sides (pitch 5.08 mm, cone 1:16). Embedment side which accepts load at the time of fitting the pipe joint into the coupling part , operating by compression, is made at an angle of 10 oC. That ensures easy fitting of the pipe into the coupling and reduces thread sticking.

2. Three degree deviation of the profile support side allows the risk of the pipe threads coming out of the mating with the coupling thread to be reduced when it is stretched hard or bent.

3. Seal is ensured by pressure of the thread sealant in the design gaps of the threaded joint profile. If specified by user, it is permissible to produce a threaded joint with fluoroplastic sealing ring in the coupling which provides an additional sealing unit.

4. Correctly assembled joint is considered to be the following one: when the coupling end coincides with the end of thread runout or is no more than 5 mm short of reaching it.

Principle of action

• The fluid from the pump of the well is cleaned from mechanical particles passing through the filter element made of the wedge profile of AISI 304, AISI 316 stainless steel, which is wound onto the support elements in a spiral with a certain pitch to provide the screen with a rigid longitudinal slits are strictly determined clearance. Sharp edges create an arch (sandy bridge) over the individual sections of the gap, and the permeability over these sections is retained.

• In the lower portion of the filter, in the bore of the filter housing, the spool piece is set, which comes into operation in case of a complete clogging of the filter element. Due to the pressure difference inside the filter housing and in the plug under the spool piece, the spool piece moves upward to align the holes with a groove in the spool piece. Reciprocation of the spool piece caused by movement of the produced fluid, provides a selfcleaning of filter from impurities.

Application

The slotted filter is used to filter the product extracted from the foreign substances and contaminant ingress.

Advantages

• stable throughput in a period of full life cycle with the ability to self-cleaning;• stable operation of downhole pumping equipment due to increased filtering surface;• lowest grit of the filter element through the unstable position of mechanical particles on the filter surface and cleanliness of wedge profile surface;• high structural strength in the axial and radial direction by increasing the number of support elements;• high corrosion resistance and resistance to aggressive acid-alkaline agents.

Lease of multiphase screw pumpsPrinciple of action

A distinctive feature of multiphase pumps is small-stroke double-threaded screws, having a large number of strokes in the working area of the screw. The principle of operation of the pumps is based on the fact that a multiphase mixture (fluid, gas, suspended particles) pass to the pump through the inlet suction is divided into two streams, filling the space between the turns of the screws, since the screw thread is formed in different directions. The mixture moving along the axis of the pump to the center, is forced into decreasing space, increasing the pressure. The pressure of such pump can reach a value of 65 kg/s/cm2. Herewith a low pressure can be at the inlet (0.5 kg/s/cm2).

The types of pipelines with thermalPurpose

Pipelines in polyethylene cover for underground laying.

Application

The protective cover (made of polyethylene) protects the foamed polyurethane insulation layer from moisture attack, mechanical damage, prevents the diffusion of polyurethane and provides the pipeline with high level of protection against corrosion. Polyethylene as a protective cover is used because it is the most efficient material for underground laying of pipelines.According to the requirements of the standard GOST 30732-2006, galvanized sheet steel cover with spiral folded seam is used for above-ground laying of the pipelines. This kind of cover is resistant to ultraviolet solar radiation and atmospheric precipitation, unlike polyethylene cover.

Advantages

The cover may have different thickness (from 0.55 to 1.0 mm) depending on the diameter. The cover is very durable and stands the pressure of foaming of polyurethane.There are two design variants used for the most popular diameters of steel pipes and having different thickness of insulation layer: standard insulation for pipelines used in regions with moderate climate and southern regions, and reinforced insulation for regions with cold climate. Thickness of insulating layer is chosen according to the heat loss allowance defined in GOST 30732-2006.On the client’s demand, it is possible to manufacture a pipeline with off-standard diameter, material of the pipe, thickness of insulation layer, linear dimensions, etc. The steel pipe used in pipelines for special applications can be provided with anticorrosion covering (also on the client’s demand). The use of foamed polyurethane of well-known manufacturers guarantees high quality of the product and reliable operation of the system with heating agent temperature of +140оC (a short time rise to +150оC is acceptable).Steel pipes complying with the standards GOST 20295, 10704, 10705, 10706, 8731, 8733, etc., are used as the inner elements. Quality of pipes is guaranteed by the certificates from the manufacturers. Quality is controlled by the certified laboratory on all stages of manufacturing from raw materials to the finished product.

Purpose

Constant monitoring of the pipeline elements’ actual conditions allows to avoid high expenses on repair and on accident damage control, ie to make economically efficient repair if necessary. The system can operate in the manual localization mode during maintenance check and in the automatic localization mode in a working heating network. It gives the client the possibility to control the quality of construction and maintenance before the work is finished, ie before the pipeline is covered up with soil. Also, during the operation it allows to reveal the insulation damage before the steel pipe begins to corrode. If the insulation damage is reveal on early stages, there is no need to switch off the heating agent and to replace the steel pipe.

According to the standard GOST 30732-2006 we offer pipelines with foamed polyurethane insulation completed with signal wires of SRRM (monitoring wetness of the insulation for revealing of leakage).

Operating principle

The basic principle of operation of the SRRM system is a change in electric insulation of polyurethane foam when insulation moisture. Monitor of the insulation status involves measuring of the resistance of the signal wires laid in the insulating layer between the steel pipe and plastic pipe with respect to the steel carrier pipe. Even the slightest moisture of thermal insulator leads to a sharp resistance drop and the SRRM signals a need for operative treatment.

Heat-insulated pipeswith composite insulation

Purpose

For the safe and durable anticorrosion protection of outer surface of steel pipes, pipes pieces and pipelines’ parts we offer services on the application of outer protective polyethylene coating in the factory environment of the following types:• outer protective two-layer coating on the basis of extruded polyethylene on the steel pipes 57–1420 mm in diameter;• outer protective three-layer coating on the basis of extruded polyethylene on the steel pipes 57–1420 mm in diameter.

Application

They are designed for the construction of gas pipelines, oil-pipelines, water pipelines, and also for the construction of utility systems (water pipelines, water carriage).

Advantages

In the comparison with traditional, bituminous–mastic and polymer band coatings the industrial polyethylene pipes’ coating has the high toughness factor, elevated adhesion to steel, resistance to driving, breaks, abrasive wear. On the account of good adhesion it is stable to the shear loadings appearing during the ground settlement and during the process of pipelines parts movements during the productive activity.

The quality of outer polyethylene coating of pipes and pipelines’ parts applying in our conditions obeys GOST P 51164, GOST 9.602. The product is certified by the number ROSS RU.11H007.H00019. There is the permission for application № PPC 00-26706.

Three-layer polyethylene coating of pipes is differed from two-layer coating, because it has one more layerepoxide primer. The epox-ide layer provides the elevated adhesion of coating to steel, adhesion water resistance and firmness of coating to the cathode shell-ing. The polymer adhesive interlayer is the second, intermediate layer in the construction of three-layer coating. Depending on the di-ameters of pipes the total coating thickness is 1,8 at least (for pipes up to 114 mm inclusive in diameter) and 3,5 mm at least (for pipes 530–1420 mm in diameter). The service life of coating is 15 years at least.The used materials can be domestic and foreign.
