Appearance of Rotary Steerable Systems (RSS) allowed changing of traditional technology and increasing of techno-economic performance of well drilling.

One of the components of successfully carrying out drilling operations with use of RSS is a competent approach to selection of drilling tools capable to realize all the potential of this system. Special attention should be given in accounting for two main types of RSS according to method of bit displacement control relative to well axis:1. “Push the bit” – radial displacement of whole assembly or its major part with respect to well axis;2. “Point the bit” – positioning of bit is achieved by means of tilting drive shaft with respect to BHA.

Two different RSS types require widely different bit designs.

Lateral and axial loads are accounted for in the cutting structure’s gauge length and its aggressiveness. Cutting structure durability must correspond to RSS requirements.

BURINTEKH produces bits for both types of RSS.

Bit performance data and drilling companies’ responses allow us to proudly state that our bits are competitive with world manufacturers’ bits and surpass them in some rates.

High quality bare pipes of domestic and foreign manufacturers are used in producing core barrels. All components pass strict quality control. Core barrel design is multi-purpose and allows using one barrel for coring isolated and non-isolated core due to using fiberglass core tubes and insulating fluid.

Core Barrels

Distinctive design features of “buRIntEKH”, Ltd. core barrels:• Increased body diameter and reinforced threads increase service life and

provide continuous trouble-free operation of core barrel;

• Core tube tapered thread considerably speeds up make up and lay down operations;

• Inner core tube suspension design allows making fast clearance adjustment between core head and inner-tube shoe and, if necessary, change standard heavy series thrust bearing within 10-15 minutes at rig site;

• Collet core-cutters have necessary elastic characteristics due to special heat treatment technology and equipped with high roughness cover of tungsten carbide throughout inside diameter, which provide reliable core catching during brake-off and pulling-out operations;

• The variety of toggle-type core catchers allows selecting overlapped core tube cross-section area depending on type of formation for reliable core keeping during pulling out operation;

• Spiral centralizers decrease vibrations and fluctuations and allow increasing of core recovery percentage in fissured, cavernous and broken formations.

In contrast to “overhead” one trip system “overhead Hydro” does not require support on bottomhole (cement plug). Fixation of whipstock in casing is provided due to special hydraulic anchor, which activates under the effect of high liquid pressure created in pipes. Whipstock and window mill have special fluid drive providing transmission of hydraulic power to anchor. Other components are the same as for “overhead” system.

• Hydraulic anchorDesigned for fixation whipstock in casing without support to bottomhole. Anchor design allows, if necessary, retrieving whipstock and anchor from the well. Anchor is multi-purpose and can be used in two casing sizes.

• Hydraulic pipe anchorDesigned for fixation whipstock in casing without support to bottomhole. Anchor provides reliable fixation excluding axial and tangential displacements because of high shearing resistance due to large operating surface.

• WhipstockDesigned for providing necessary tilting of milling assembly with respect to bore axis during window milling. Whipstock is multi-purpose and can be used in two casing sizes.

• Window millDesigned for casing window milling and sidetracking. Cutting structure of all window mills is made up of tungsten carbide plates and granulated hard alloy.

PuncherDesigns of all punchers are protected by patents of Russian Federation.

modernized pipe puncher ptm is designed for punching 8…25 mm holes in tubing and casing from 60 to 168 mm of domestic and foreign manufacturers to make a communication between the interior cavity and the exterior annular space. This hole provides circulation restoring, prevents pulling pipes with fluid out of wellbore, and refilling into cement sheath and decreases environmental pollution while well workover operations.

Punchers are produced of several series: ordinary – K, for application in gas medium – G, for application at depth 3000-6000 m – VD.

Punchers are run in a hole on wire, cable, flush-joint pipes or by throwing off.

Potential energy of a fluid column and pumping unit pressure are used to actuate a puncher.

JARS

Our hydraulic and mechanical jars are designed for releasing a stuck downhole tool by up-and-down impacts with static axial load (tension) and torque. Jars are included in drilling assemblies for sidetracking. We produce right and left hand fishing and drilling jars.

Today, we produce a brand-new torsional jars purposed for releasing a stuck tool by up-and-down torsional impacts.

Design of axial jar is own “BURINTEKH”, Ltd. development protected by Russian and foreign patents.

Main advantages are:• Singular case thread (between body and bottom sub);• Compactness which allows transport it on pickup and deliver it to hard-to-reach areas

on helicopter without external suspension;• Absence of extreme loads to hydraulic cylinder appearing during jar performance;• Ability of quick repair by changing hydraulic cylinder;• Jars for upward and downward impacts are different tools and can be placed in the

drillstring independently from each other or only one of them.

Hydraulic jar yAGb-172 is produced of several series: ordinary – yAGb-172, for rotary BHA – yAGb-172R, for working at high pressure – yAGb-172VD.

Axial Jars

torsional Jars “sHOCK tURN”Design of torsional jar is own “BURINTEKH”, Ltd. development protected by Russian and foreign patents.

Why is stuck tool released by only up-and-down impacts along well axis? In fact, life experience suggests that for pulling, for example, driven nail out it is better not only pull it, but pull with simultaneous turn. Obviously, it is easier to free stuck downhole tool if not only axial impact loads but also shock torsion torque are applied. To solve this challenge, we developed torsional jars “SHoCK tuRn”, which can affect stuck tool by clockwise and counterclockwise and up-and-down impacts in different combinations.

Main advantages are:• High power capacity. Torsional jar impact strength 5…6 times bigger than ordinary

jar;• Singular case thread (between body and bottom sub);• Compactness which allows transport it on pickup and deliver it to hard-to-reach

areas on helicopter without external suspension;• Absence of extreme loads to hydraulic cylinder appearing during jar performance;• Ability of quick repair by changing hydraulic cylinder;• Extended functional capabilities.
