Appearance of Rotary Steerable Systems (RSS) allowed changing traditional technology and increase 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.

As an achievement should be noted matrix bit with long gage part for RSS in complicated conditions in Venezuela fields. There was successfully drilled well with high ROP rates. Bit was in perfect condition after drilling.

Bits are designed for wiper trips and reaming in low abrasive soft and medium formations at high ROP. Body profile and cutting structure prevent from accidental sidetracking in abnormal bore. Bits are equipped with tungsten carbide teeth and PDC cutters.

Is possible to manufacture bits with different diameters (3

3/16 -12

1/4 in.)

As the competition in the oilfield increases BURINTEKH, as a market leader, aims to satisfy all our customers’ requirements. Currently we are developing a new product-line – “Roller Cone Bits”.

In 2010 roller cone bit manufacturing facility was acquired in USA having more than 37 year experience of creating high quality rock destruction tools, smoothly running and permanently upgradable manufacturing technologies, which produce API/ISO certified production for internal and external (including Russian) markets.

In 2012 roller cone bit manufacturing was organized in Ufa city. Big work was done, up-to-date equipment was purchased, specialists with wide experience in roller cone bit manufacturing were staffed who are regularly sent to USA for training and qualification upgrade. American professionals permanently present at manufacturing, control the quality of operations at each production phase. We have a modernized researching laboratory and test-bench, which help to control and improve quality of production.

Currently we produce roller-cone bits of 1 and 2 class the body and sectional types meeting demands of most exacting consumers concerning quality, effectiveness and reliability.

Universal bits “Z” series

“Z” series includes wide range of bits for working in any mining and geological conditions.All bits of this series are equipped with options of reinforcing shirttail and back taper which allows using it in conditions of directional drilling.

Bearings of bits are equipped with o-ring seals made from the best modern materials, bushings and washers of maximum sizes which allow applying high axial weights on bit and receive maximum rates of penetration in drilling hard rocks.

The best stability results are achieved by these bits in low inclination intensity (up to 30 degrees) and low values of bend settings (up to 1,25 degree).

Bits of this series are admitted to use with high WOB (more than 15.5 klbs per 3

5/16 in.).

Bits of “ZW” series are purposed for construction deviated wells and drilling with high build-up rate.

The main feature of these bits is design of sealing unit consisting of two big rectangular section seal rings. In combination with strict tolerance system in manufacturing process and patented pressure compensated system this design gives ability to considerably increase bit bearing stability.

This series also includes all range of bits for any mining and geological conditions.

Small diameter bits

Series includes bits with diameter from 4 3/4 to 6 1/

8 in. developed for sidetracking and drilling sidetracks.

Bits are produced as with carbide so with milled cutting structure.

The main feature of these bits is the six-point stabilization system allowing facilitating its performance in horizontal conditions and prevent eccentric rotation destructively affecting bit bearings.

This series well-proved itself in field tests and showed bearing stability over the 50 hours of drilling on the bottom without bearing seal failure.

To protect cutting structure from erosive wear the option of carbide flame spraying is accessible.

Permanent works for improvement receipts and structure of sealing material. All our bits are equipped with new reinforced sealing material of increased stability.

Bushings and washers made from extra strong alloy covered with silver decrease friction coefficient and increase bearing operating life.

Labyrinth gland with special bent path prevents abrasive penetration to bearing units increasing operating life of bearing unit.

Special ledges and teeth help cleaning heel of roller from sludge.

Special grease distribution and circulation system provides effective heat transfer from bearing.

Innovative receipt of cup grease developed together with sealing material which allows facilitate operation mode and increase bearing operating life.

Pressure compensation system allows neutralize deleterious effect of hydrostatic head pressure at great depths.

Control over sealability of all bit sections guarantees hundred percent reliability of lubricating system

Lubrication system

Gauge

All roller cone bits have full set of options for directional drilling:

• Enhanced gauge, reinforced with double quantity of tungsten carbide inserts, perfectly protects bit while high dogleg severity drilling and allows maintaining nominal well diameter;

• Shirttail hardfacing protects seals from early wear;

• Additional reaming gauge rows – patented technology protecting seals from overheating due to friction between bit and wellbore.

It is possible to use diamond options on all bits.

Underreamers RRRR–118–127–1

RR-94-142-1 Сп

RR type underreamers are designed for enlarging any interval of wellbore (for liners, profile shutter, repair and insulation work intervals) in soft and medium hard formations.

RR H type underreamers are designed for reaming while drilling as a part of BHA comprising pilot drill bit or previously drilled interval.

RR Sp type underreamers are designed for carrying out special operations in openhole intended to form a cavity within a wellbore for further intentional sidetracking from original hole.

Expansion of blades, equiped with high quality PDC cutters, into operating position is provided by the effect of differential fluid pressure between flowbore and wellbore annulus.

Delivery set of all types of underreamers includes back pressure valve which prevents tool from sludging during round-trip operations and interchangeable blades easily replaceable in rig conditions, significantly reducing repair and maintenance costs.

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.

Impact assembly

Impact assembly is two-section jar made as separate sections: top hydraulic jar (top section) and bottom mechanical jar (bottom section). There are produced the following assemblies: assembly jar yAGB-114 and jar yAMB-114H; jar yAGB-124 and jar yAMB-124H; jar yAGB-172P (or yAGB-172BD) and jar yAMB-172H.

Advantages:• Ability of use jars as in assembly so as separately;• Transportation is simplified because of compactness;• Ability of separation jars lengthwise in assembly (installing pipes of necessary length between jars).
