? Safe system to control drawworks drive when hoisting, lowering, braking drilling tools and in the mode of automated bit feed
? Use of the latest diesel electric power stations leads to maximum efficiency
? Application of the latest computerized control of the drilling rig increases work efficiency and makes it possible to perform constant monitoring of the drilling process
? Application of Varco TDS-9SA top drive
? Application of Swaco high-performance mud treatment units and centrifugal pump units produced by Mission
High efficiency of drilling is achieved due to application of adjustable DC drive. System to control main units is made on the basis of microprocessing controllers. In this case the system safety is increased by means of self-diagnostics. Choice of optimum modes in the course of drilling as well as lifting and handling operations makes it possible to reduce electric power consumption by 15%. Auxiliary drive makes it possible to hoist the drill string in case of emergency power cut off from the main power supply source using emergency diesel electric power supply station. Drawworks is controlled by means of one handle – joystick on the driller's remote control panel. Folding self-elevating floor makes it possible to mount the equipment at the drill floor at 3.4 m height. Reduction of time for mounting and dismounting works as well as transportation is the main advantage of the new drilling rig because main mechanisms are installed in modules with built-in road bridges.
Drawworks module
Drawworks module includes biaxial semitrailer with the following mounted equipment:
?Drawworks, auxiliary drive, stabilizer, rotary drive
?Drawworks lubrication system, drawworks air channel and rotary drive, auxiliary equipment
The module provides:
?Drawworks operation
?Drawworks operation with auxiliary drive
?Suppression of drill line oscillation while drum winding
?Electric lighting of the working places at night with lamps installed at the shelter
Drawworks is powered by electric motor of the main drive which delivers rotation to the main shaft of the gear transmission by means of gear clutch. Then via the gear transmission, rotation is delivered to the countershaft and via the following gear transmission to the hoisting shaft. In case of main drive failure drawworks may operate with auxiliary drive. In this case rotation via chain transmission is delivered to countershaft, installed in transmission.
One-speed drilling rig LBU-670ET1-M is equipped with the drum with thread for 28 mm diam. cable, gear transmission, DC motor of 1000kW, frame, Eaton 238DBB parking plate brake at the hoisting shaft, second Eaton 215DBB small brake at the intermediate shaft. At the countershaft of transmission there is a chain wheel to deliver rotation from auxiliary drive. Connection of this shaft to the drive shaft of transmission is performed manually with gear wheel. Switching mechanism is installed outside in the transmission cover. To supply power to Eaton parking brake air channel is provided. It is connected to compressor, and compressed-air cylinder is provided for emergency unbraking.
The novelty of the drawworks is due to the lack of chain transmissions, tire-type pneumatic clutches, electromagnetic or hydrodynamic brake, band brake and brake lever, gear shift which are typical for traditional drawworks. Equipment and drive of the drawworks module are remotely controlled from panel in the driller's cabin. Auxiliary drive with asynchronous 55kW motor is connected to the chain transmission of the drawworks. The module holds rotary drive of 1000kW DC motor with gearing to the rotary table by means of drive shafts and angle countershaft. Two auxiliary hydraulic drawworks are installed in the module. Shelter of the module is made of three-layer panels. The module also holds site for maintenance of mechanism fastening the fixed end of the drilling line.

Drill floor is lifted in the operating position after installation of the specified components at the transport module of the rotary table; moreover, the driller's cabin is mounted at the floor. Drill floor is lifted by means of the block-and-tackle system with lifting straps. The floor is fixed in the operating position by bolts in the top part of the floor and with side screw rods.
Drill pumps modules
Modules of drill pumps #1 and #2 include drill pumps UNBT-950L2 with drive capacity of 950kW. These pumps differ from the previous modules due to L-shaped hydraulic block, which makes for reducing voltage in borings crossings what increases the useful life of the block. Lubricating and cooling systems of the piston-cylinder unit provides intense heat takeoff from friction surface and prevents air inflow on the opposite side of the piston. The structure contains bimetallic bushings, significantly increasing life of piston-cylinder block.
Application of a more powerful pump makes it possible to increase the travel speed with increased pressure and to reduce drilling time. Besides the specified equipment the module includes 1000kW DC motor, pump drive with four poly V-belts, pumps piping, load beam with hand tackle.

Cluster drilling rigs are designed for cluster drilling of oil and gas wells with rated drilling depth of 3200-6500 m. The rigs have the latest electric drive providing gradual control of main rig components.
Design features of cluster drilling rigs are specified by cluster drilling which became widespread in Western Siberia in the course of waterlogged areas development due to roads impassability. Cluster drilling makes it possible to reduce costs for rigging-up operations, engineering development of well sites, construction of access roads to the field, as, in the course of drilling, the rigged-up equipment is moved within the cluster. Equipment package for cluster drilling includes mobile and fixed components, thus, only main part of the equipment for well drilling is moved from one well to another one.
Lately the rigs of a new generation (EK-BM series) have been designed and replaced the legendary rigs (3000EUK) which had been successfully operated since 1978. They have some peculiar features, and first of all, block-modular configuration. Such package of full factory readiness makes it possible to simplify and to accelerate the first rig-up as well as to reduce time for mounting-dismounting works when moving the drilling rig within the cluster.
The configuration of the drilling rigs reflects all main positive decisions proved by the long-term experience of cluster drilling rigs operation at the fields of Western Siberia. To create comfortable working environment, housing facilities of the drilling rigs are equipped with heated floors, shelters and heating air-and-steam units with the closed circulation system.
Main rig components are driven by electric motors of direct or alternating current from industrial networks via SCR which allows to choose the optimum drilling mode and to set up various combinations of rotary revolutions, drilling mud supply and bit axial load.
As per the Customer's requirements it is possible to change the drilling rig package in conformity with the specific operating conditions.

CLUSTER
Main features of the drawworks
?Multifunctional drive. Electric motor of the drawworks drive provides not only hoisting but also the controlled lowering of the drill pipes and casings. It also provides complete stoppage and holding of the load in the fixed position. Therefore, the auxiliary brake is not required. While drilling, the motor functions as bit feed controller. In case of emergency power supply cut-off, it is possible to hoist drill pipes by means of the motor powered by diesel electric power station of partial capacity
?Control system provides total control of driving electric motors while hoisting, lowering and intermediary modes, i.e. provides braking while hoisting and acceleration while lowering
?Gear transmission consists of three gears which provide two speed levels at the hoisting shaft: “quick” and “slow”. “Quick” gear provides lifting and lowering of drill pipes and empty elevator. “Slow” gear provides lowering of heavy drill pipes and casings and accidents prevention. Gear wheels are made of high-performance steel, wheel gears have special strengthening parts
?Drive of disk brakes is pneumatic. Due to the fact that electric drive of the drawworks functions as the brake, disc brake is used only to fix loads in the fixed position
?Drum thread and ledges protection increase life time of the drilling line and hoisting drum. The thread makes cable winding better and is made at special straps, which are welded to the drum. When the thread is worn out, the straps may be replaced. To protect ledges of the drum against wearing out, end straps made of wear-resistant steel are provided
?Noncontact sealing of shafts makes it possible to prevent oil spills outside from the transmission body
?Remote control creates comfort labor conditions for the driller. The driller may operate in the sitting position. Gear shift from “quick” to “slow” is rarely performed because in majority of cases all operation of the drilling string is performed at “quick” gear

Drawworks of ET series
Drawworks of ET series has a unique design. The range of drawworks with lifting capacity within 160 and 500 tons provides efficient work while tripping and drilling operations.
Drawworks of ET series have been designed by -drilling equipment. The
unique structure of ET series drawworks makes it possible to refuse from traditional structural components: chain transmission, tire-type pneumatic clutches, electromagnetic or hydrodynamic brake, band brake and brake control handle. Size range of drawworks with lifting capacity within 160 and 500 tons has a unique kinematic configuration and structure. Drawworks are equipped with DC electric drive, operating as per scheme “thyristor converter-drive”.
Distinctive feature of ET series drawworks: drawworks frame and gear transmission body are mounted at the welded metal ware and hoisting shaft of the drawworks and output shaft of gear transmission are combined into one unit. Drawworks are simple and compact. Their weight is much less compared to traditional chain transmission drawworks.
Gear transmission of the drawworks provides “quick” and “slow” speeds at the hoisting shaft. “Quick” speed is required for hoisting and lowering of the drill string and elevator, “slow” speed is required for casing operation and accidents elimination.
Multifunctional drive of the drawworks provides hoisting and adjustable lowering of the drill strings and casings, elevator up till complete stop and suspending in the fixed position; adjustable bit feed to the well head in the mode of bit feed controller. In case of main power supply failure, the motor performs hoisting of drill pipes, powered by the diesel electric power station of 200kW capacity. For fixation of the drum the disk brake is applied. The disc brake consists of two disks and two drive systems (operating and emergency). Drum with the thread for Lebus cable has protective flanges with ring straps made of low-resistant steel. Transmission has contactless seals of a peculiar structure preventing oil leak outside as well as dust and wet getting into the transmission body. The seals do not have wearable details of collar type. Remote control provides comfort working conditions. It is required to control the handle of command device of motor control system. The driller may work in the sitting position.

DRAWWORKS MODULE LBU-750E-SNG
Basis and originality of the drawworks module consists in the mounting of drawworks equipment and auxiliary drive at one frame of drawworks module.
Drawworks module LBU-750E-SNG has: two-speed gear transmission, multifunction drive, contactless seals of gear transmission shafts, auxiliary drive with DC electric motor that functions as bit feed controller, emergency drive and remote control. Main drive of the redesigned drawworks module LBU-750E-SNG and its auxiliary drive transmit the torque to the hoisting shaft independently of each other from different ends of the hoisting shaft.
Gear transmission of the drawworks provides “quick” and “slow” speeds at the hoisting shaft. “Quick” speed is required for hoisting and lowering of the drill string and elevator, “slow” speed is required for casing operation and accidents elimination. Multifunctional drive of the drawworks provides hoisting and adjustable lowering of the drill strings and casings, elevator up till complete stop and suspending in the fixed position; adjustable bit feed to the well head in the mode of bit feed controller. In case of main power supply failure, the motor performs hoisting of drill pipes, powered by the diesel electric power station of 200kW capacity. For fixation of the drum the disk brake is applied. Drum with the thread for Lebus cable has protective flanges with ring straps made of low-resistant steel. Transmission has contactless seals of a peculiar structure preventing oil leak outside as well as dust and wet getting into the transmission body. The seals do not have wearable details of collar type. Remote control provides comfort working conditions. It is required to control the handle of command device of motor control system. The driller may work in the sitting position.

MUD PUMPS
Mud Pumps for drilling rigs are produced in two-cylinder (UNB) and three-cylinder (UNBT) configuration, with L-shaped and direct-flow hydraulic boxes, with capacity within 600 and 1600 kW.
Mud pumps are designed to provide flushing process while hole making, drilling mud injection into the well for bottom hole cleaning and borehole cleaning off drill cuttings and its lifting to surface, drilling bit cooling and hydraulic down hole motors putting into operation. URBO – drilling equipment produces pumps of the following types – two-cylinder pumps UNB-600 and three-two-cylinder single-end pumps UNBT with capacity within 600 and 1600 kW.
Three-cylinder single-end pumps provide the least pressure irregularity at the output and the least wearing capacity of valves and piston rods compared to two-cylinder double-end pumps and they most precisely correspond to the requirements of drilling technology.
Hydraulic seal of the cylinder-piston unit prevents air suction on the back side of the piston and gasing of the drilling mud. Besides, the unit provides lubrication and cooling of the friction between piston and cylinder. Two-chamber seal of the slide rod prevents oil leaks from the crankcase and its pollution with the drilling mud. Reducer lubrication system consists of two parts: compulsory one and gravity one from the storage bins. Compulsory lubrication system provides constant oil pressure keeping in oil lines. Forged hydraulic boxes made of high-strength alloyed steel and ion nitriding of the gear transmission guarantee the specified life time of the pump. Capacity and pressure of the pump at each diameter of the piston makes it possible to perform hole making technology by means of forced drilling mode.
Safety valve of the blocking device cuts off the drive of the mud pumps when the pressure is increased in the discharge pipe with simultaneous discharge of the excess pressure.
Configuration of the manufactured pumps makes it possible to apply the drive transmission on any side of the pump or on both sides.
