The invention relates to a universal hydraulic mobile drilling rigs of the middle class in terms of carrying capacity, which allow implementing the main existing drilling technologies.
The well-known hydroficated mobile drilling rigs of medium payloads of the main world analogues include the following main attachments installed on the chassis: subframe with outriggers, hydraulic actuator, mast, movable rotator with swivel, table, breaker / dokrepitel threads, elevator or without it, main winch for casing launching or without it, auxiliary winch, manipulator / feeder of drill and casing pipes, piston and / or centrifugal mud pumps, compressor, manifolds, control panel with or without a driller’s cabin.
The main difference between the known analogues is in the construction of the mast. Some have a solid static construction (non-telescopic) masts for drilling and casing pipes up to 9 m long with an additional extension for pipes of greater length.
There are known non-telescopic masts of drilling rigs of analogs, in particular, Italian RgaMs P8-500 (uuTga81esot), Ma // ep5a ΜΙ-50 (\ u \ u \ ulpa55sp / up5l1). Igshtee 045 (yyy.ygStes.sov); or German Pr-1 RB-50 (yyy.rgak1a-Lob! eskk.ye), A0B0 0750 (yyyyadohoye), Ε + Μ I-4 (yyy.teygShshdsotov).
They are characterized by the fact that the one-piece box mast, possibly with an extension, is made with a cable (rope) or chain multiplier for the rotator carriage with one row of guide rollers, cables (ropes) and chains are not coaxial, but cantilevered to the axis of the rotator, are supported on the carrier beam a subframe of a drilling rig, either with the help of two supporting legs of hydraulic jacks on the ground, or with the help of one supporting foot with a cylindrical bearing surface. The mast extension is very cumbersome and inconvenient (it must be additionally mounted on each well, dismantled in the transport position).
Other well-known analogues of drilling rigs have a telescopic movable mast for the entire range of pipe lengths up to 14.5 m. The latter option is mainly used for drilling rigs with a higher carrying capacity of 50 tons and more. In addition to the Igshtes company, they are produced by American companies ZsNgatt 50–200 tons (since 2003), AIKasSorso 125 tons (from 2011), and the German company Risla-Waieg 125 tons (from 2012).
Known telescopic masts of drilling rigs are analogs of IgShtes 0-55, (Italy) [1], 8gbtt Τ130ΧΌ (USA) [2].
They have a telescopic mast with a cable (cable) 2-fold multiplier of the rotator carriage stroke, a crown block with two or one row of guide rollers, cables (ropes) of the multiplier are coaxial with the axis of the rotator, the bottom of the mast is supported on the rig bearing frame of the drilling rig or using 2 supporting paws-jacks on the ground.
In both types of masts of analogs, hydraulic hoses with or without a cable layer (cable chain) are parallel to the mast from the side. This non-compact design can lead to a conflict with the drilling manifold (clinging, grazing). If there are two rows of rollers in the transport position, the crown block must be rotated 90 ° to the horizontal plane to reduce the overall height of the drilling rig in the transport position.
Known drilling rigs also have differences in the equipment, providing lifting operations (hereinafter SPO) with drill pipes (BT) and casing pipes (FROM).
The following well-known structural solutions can be distinguished, providing different ways of seizing pipes.
In Italian production Igshtes, \ uek in particular, [3], [4] -equipment, providing open source software, is characterized by the retention of BT for locks. At the same time, oil and other assortment drill pipes with drilling threaded locks are used.
The rotator of these analogs is movable, inclined or not inclined, by-pass. Table - side, clamping with universal wedge jaws, dual (integrated) with a unified hydraulic clamping breaker / dokrepitel threads with wedge jaws and a roller clamping centralizer. The BT is supplied to the rotator with the help of various feeders or with the use of an auxiliary winch with or without a revolving manipulator. If the rotator is not inclined, the upper thread of the BT is screwed in the upper vertical position of the rotator, which is not very convenient. If the rotator is inclined, then the upper thread BT is screwed in the lower inclined position of the rotator. The capture of the upper end of the BT during the descent and ascent of the BT into the well is made by screwing the spindle of the rotator into the thread of the lock or using a hydraulic or mechanical elevator.
The following advantages are distinguished from these well-known design solutions: the fastening / reinforcement of BT is made without the use of manual labor, quickly, conveniently. In the presence of a feeder-manipulator SPO are carried out without the participation of the hands of workers, which increases the degree of safety of work. The disadvantages include the bulkiness of the double table, which in this case is intended only for drill pipes and threaded casing pipes. For planting welded casing pipes with a diameter
- 1 029885
more than the passage of the table (500 mm) it is necessary to divert the table to the side and hold the pipe with clamps at the mouth on the ground. In addition, when lifting a drilling tool with a diameter greater than the table aisle (500 mm), it is also necessary to take the table away and “re-chain” on the ground below directly below the table before it drops, which is extremely inconvenient. The method with vertical screwing of the upper thread in the upper position of the rotator is not convenient (it is hard to see and slowly).
The analogues produced in Germany [5], [6], [7] - equipment that provides the SPO, is characterized by the retention of BT for the body of the pipe with the help of semicircular sponges, removable for each individual pipe diameter. This method is universal for BT and casing - both threaded and welded. At the same time, only own drill pipes are used - from the manufacturer of the drilling rig, specially designed and manufactured by him.
Rotator movable, inclined, folding. A table - oar, clamping with semicircular individual sponges. The fastening and reinforcement of the threads is made with the help of one or two suspended drill wrenches driven by a hydraulic cylinder. The supply of BT to the rotator is provided with the help of an auxiliary winch manually. The capture of the upper end of the BT when the BT is lowered into the well is made by screwing the rotator spindle into the lock thread in the lower inclined position of the rotator. The capture of the upper end of the BT when lifting the BT into the well is performed using an additional hydraulic or mechanical elevator that clings to the spindle. The following advantages are distinguished in these well-known design solutions: a swinging table can pass a chisel and casing of large diameter through itself without additional inconvenience, while ensuring retention of both drilling and casing pipes, including threaded and welding. Disadvantages: the presence of manual operations (fiber) when unfastening / reinforcing and supplying the BT to the rotator, which is difficult and dangerous. Limited assortment (in terms of drill pipe) capabilities due to the preferential use of only special BT and the limited use of the most common BT oil assortment. Casing mast extension over 9 m is very cumbersome and inconvenient to use. The analogues produced in the USA [2] and [8] have the equipment that provides the SPO, characterized by the retention of the BT by the lock slots with a fork or wedges for the pipe body. In this case, in the first case, only special BTs with slots are used.
Known drilling complex [9], which includes a drilling rig with a manipulator, transport carts for the transport of drilling tools, pump-compressor unit, pipe unit, including the chassis with the frame and rack. The complex is equipped with a manipulator placed on the pipe block, hingedly fastened to the rack and guides made with stop bars of the displacement of the drill pipe, a device for vertical movement of the guide rails placed between the rack and the frame of the pipe block by the cylinder of the rack rise. The rack is hingedly fastened with a frame. Known drilling complex provides a reduction in time for preparatory operations and facilitation of auxiliary work during drilling due to the fact that in a pipe block guides with restrictors movement of drill pipes can be made telescopic. The disadvantage of this complex are significant limitations on the length and diameter of the drill and casing used.
The KV-50 drilling rig [10] and the KV-T90 drilling rig, both of the German firm Rgak1a [11], which are characterized by the following solutions, were chosen as prototypes (except for differences in the types of the mast).
KV-50 is made with a solid mast [10]. A subframe with outriggers is installed on the chassis or semi-trailer, hydraulic drive with power take-off from chassis internal combustion engine, mast, movable swivel with swivel, table, thread release / docker, elevator, main winch, auxiliary winch, piston and / or centrifugal drill pumps, manure manure manure, manure manure , remote control with or without a driller’s cabin.
Mast - one-piece box, possibly with an extension. Inside the mast there is a hydraulic cylinder for feeding a rotator with a cable multiplier for a turn of the carriage of a rotator with one row of guide pulleys, the ropes are not coaxial, but cantilevered to the axis of the rotator. The feed cylinder provides only 30% of the maximum carrying capacity. Maximum carrying capacity is provided when using the main winch, including in the drilling mode. In this case, the feed cylinder is turned off. The rope of the main winch is stockpiled through the crown block mounted on top of the mast and the hook block is coaxial with the axis of rotation of the rotator spindle. In the transport position, the crown block swings (turns) down to provide the required height clearance in accordance with the general road requirements. The mast rests on the carrier beam of the drilling rig's subframe. The mast extension is very cumbersome and inconvenient (it must be additionally mounted on each well, dismantled in the transport position). Hydraulic hoses are suspended from brackets on the side parallel to the mast. This non-compact design can lead to a conflict with the drilling manifold (clinging, grazing). Equipment that provides tripping operations (SPO) is characterized by the retention of the BT for the pipe body with the help of semicircular sponges, removable pipes that are individual for each diameter. This method is universal for BT and OT - both threaded and welded. At the same time, only own drill pipes are used - from the drilling rig manufacturer, specifically
- 2 029885
developed and manufactured by him. The capture of the upper end of the BT when the BT is lowered into the well is made by screwing the rotator spindle into the lock thread in the lower inclined position of the rotator. The capture of the upper end of the BT when lifting the BT into the well is performed using an additional hydraulic or mechanical elevator that clings to the spindle.
Rotator movable, inclined, folding. A table - oar, clamping with semicircular individual sponges. The fastening and reinforcement of the threads is made with the help of two suspension drill wrenches driven by a single-acting hydraulic cylinder. The BT is fed to the rotator using an auxiliary winch with manual labor. Advantages: the swing table can pass a chisel and casing of a large diameter through itself without additional inconvenience, while at the same time retaining both drilling and casing pipes, including threaded and welded ones. Disadvantages: the presence of manual operations (fiber) when unfastening / reinforcing and supplying the BT to the rotator, which is difficult and dangerous. Limited assortment (in terms of drill pipe) capabilities due to the preferential use of only special BT and the limited use of the most common BT oil assortment. Casing mast extension over 9 m is very cumbersome and inconvenient to use.
Known drilling rig KV-T90 (prototype) is made with a telescopic mast [11]. The semi-trailer has an outrigger with outriggers, hydraulic drive with power extraction from deck ICE, telescopic mast, movable rotator with swivel, elevator, drilling platform, table, thread breaker / dokrepitel, auxiliary winch, manifolds, control panel with driller’s cabin, pipe supply system ( feeder) mounted on a separate trailer. Pumping equipment is not part of the drilling rig and is supplied separately in a standalone version. In the transport position, the height exceeds the normal 4 m, which limits and requires the issuance of a special permit for driving on public roads.
The mast is telescopic, inside which the rotator feed cylinder is installed with a 2-fold cable multiplier for the rotator carriage stroke, a crown block with two rows of guide rollers, multiplier ropes coaxially with the rotator axis, the bottom of the mast is supported on the rig bearing frame of the drilling rig and additional outriggers to the ground.
Hydraulic hoses are suspended from brackets on the side parallel to the mast. This non-compact design can lead to a conflict with the drilling manifold (clinging, grazing).
The fastening and reinforcement of the threads of the drill pipe is made with the help of two suspension drill wrenches driven by a hydraulic cylinder. Drill keys are manually put on the threaded joint. A distinctive feature is the presence of an automatic system for supplying pipes to the wellhead to trap pipes and perform tripping operations.
The disadvantages of the well-known drilling rig: non-compactness of laying hydraulic hoses on the mast, limited functionality of the base (bottom) of the mast, manual operations for loosening and reinforcing the drill pipe threads with the aid of suspended drilling wrenches, cumbersome rig and feeder mounted on a separate trailer, limitations along the length and diameter of the used casing and drill pipes.
The aim of the invention is to create a middle class drilling rig with a telescopic mast of increased compactness and simpler design, expanding the range of used casing pipes up to 13 m long and drill pipes of any known types up to 12 m long with gripping locks and reducing time and labor-energy costs for lifting operations when drilling deep wells and large-diameter wells, as well as improving the level of safety and mechanization by providing tripping operations (SPO) "without p yk ". Technical tasks in accordance with the specified purpose are solved by a hydroficated mobile drilling rig, including a drilling block, containing

The hydrated mobile drilling rig includes a drilling unit (Fig. 1) and a pipe unit (Fig. 9).
The basis of the drilling unit is chassis 1 tractor terrain with a wheel formula 6x6 (or 8x4, 8x6, 8x8), or semi-trailer, or trailer. All major components of the drilling rig are mounted on an independent frame 2 welded structure, which is connected to the chassis of the tractor with the help of rigid and semi-rigid fastening elements.
To install the subframe in a strictly horizontal working position, it is equipped with separately controlled hydraulic outriggers (stabilizers) with locking nuts resting on the supporting legs, mounted on the back of the beam, which is mounted on the ground surface and in front - directly on the ground.
The drilling equipment is installed on the nadramnik 2: a hydraulic actuator 3 with power take-off from the chassis or deck engine; Mud pumps 4 piston and / or centrifugal (not shown in Fig. 1); pneumatic compressor 5; driller's cabin with remote control 6; telescopic mast 7 with a fixed base and a movable boom with guide profiles. The equipment is controlled from the driller’s cabin with a control panel, which is made of easily assembled 4 029885
removable / removable panels.
The hydraulic drive (hydraulic power unit) 3 consists of a transfer reducer, is made with power take-off from the main engine of the chassis or deck engine through the propeller shaft from the power take-off box and, in turn, drives the hydraulic pumps feeding through the hydraulic hoses;
in the drilling unit:
outrigger hydraulic cylinders, main hydraulic cylinder (GHZ) feeding in the mast, providing tripping operations (SPO), hydraulic lifting cylinders of the mast, moving the mast in the slider, outriggers, hydraulic cylinders of the table, unclamper / dereamer, centralizer, drill key, tilt of the rotator;
hydraulic motors: rotator drive, drilling pumps and compressor, auxiliary winch; in the tube block - hydraulic cylinders: feeder (clamp, lever, pusher), manipulator, pipe
gripping the manipulator.
The hydraulic system of the drilling rig also includes an oil tank, an oil filtration system, distributors, valves, hydraulic units, pressure gauges, joysticks, regulators, control levers, rigid and flexible hoses for their connection, and other hydraulic equipment necessary for the operation of the installation.
Mast 7 contains supporting adjustable rollers, main feed hydraulic cylinder (HHZ - not shown), crown block 8, rotator 9 with swivel 10 on movable carriage 11 with guide rollers (not shown), rope multiplier with adjustment of the length of the straight and reverse (Fig. not shown), a slider based on a nadramnik 2, hydraulic cylinders for raising / lowering the mast, hydraulic cylinder for moving the mast in the slider, the corresponding hoses of the hydraulic drive and the electric wire. Telescopic mast 7 is made of welded high-strength steel, consists of two sections: the upper movable boom (Fig. 2, 3), moving on rollers along the guide profiles of the fixed mast base, which has, in turn, its guide rollers along which boom guides, driven by the main hydraulic cylinder (GHZ) and the lower one - the support (base) (Fig. 4).
The telescopic mast 7 (Fig. 1) is fixed in the slider mounted on the brackets of the subframe 2. It consists of a fixed base including a bottom with a support hinge in the form of a support heel 12 (see Fig. 4), and a movable boom with a crown block 8 (Fig 1, 2, 3) moving along the mast inside the base on the rollers along guide profiles (channels) 13 (Fig. 2, 3), the main feed hydraulic cylinder (GHZ - not visible in Fig.), Two straight cable multipliers (up) and reverse (down) stroke of the rotator 9 (Fig. 1, 2, 4, 10-14), the movable carriage 11 of the rotator, moving on p likah along arrows along the guide profiles (see. Figs. 1, 2, 3, 11). The movable carriage 11 is connected by steel cables (cables) for forward and reverse running of the cable multiplier with adjustment of the length of the forward and reverse ropes (not shown), and the cable multiplier provides double travel of the carriage 11 with respect to the length of the mast boom movement, which means that the telescopic mast is made with a double cable multiplier for the carriage turn of the rotator.
The straight run rope is fastened with two dead ends to the upper part of the mast base through adjusting lanyards adjusting the length of the rope, and the return end passing through the crown block is looped in a carriage on a pulley. Two return cables with dead ends are attached to the upper part of the mast base using tips, and the reverse ends passing through the guide rollers located on the lower end of the mast boom are fixed to the lower part of the carriage using adjustable rope length tips.
In addition to the above, the mast is secured with table 14, a straightener / dock cladding of 15 threads, a drilling manifold 16, a cable layer (cable chain) 17 hydraulic and electrical lines. The hydraulic hoses are laid and fixed in the cable layer - (cable chain) 17 (Fig. 2, 3), which is fixed on the front edge 18 of the boom and connected to the carriage by one of its ends (Fig. 2), then, between the crown block pulleys 19, moves to the rear edge 20 of the boom with the laying between the guide rollers of the multiplier ropes along the rear edge of the boom and the mast, then fastened with a special fastening 21 to the mast with its other end, is fed to the hydraulic actuator 3 (Fig. 3).
Unlike the prototype, the crown-block 8 is made with two pulleys 19 arranged in one row in guide rollers (bearings) (Fig. 2), and the rotator 9 is fixed on the carriage in such a way that the axis of the rotator 22 is oriented console with respect to the axes of the straight ropes 23 and reverse so that the ropes are misaligned with the axis of the rotator.
The mast base moves in a slider mounted on the nadramnik along guide bearings, there are two lift cylinders for the slider (mast), a hydraulic cylinder for the longitudinal movement of the mast in the slider, two extensions that additionally hold the base of the mast for the frame 2. In working (vertical or angled to horizon) position as shown in FIG. 4, the mast rests on the bottom placed in a fixed base in the lower part of the mast with a support hinge, which is made in the form of a support foot 12 with a hinged spherical surface in the form of support knives resting on a base plate 24 with steel shell. Mast performed with
- 5 029885
the ability to support the fifth 12 through the base disk 24 on the beam mounted on the ground.
In addition, additional devices are also attached to the mast - an auxiliary winch, a ladder, rope extensions, lighting lamps, etc.
The indicated construction of a mast with a double cable multiplier ensures the rotation of the carriage of the rotator along the mast 13.3 m, which ensures the use of casing pipes up to 13 m long and drill pipes of any known types up to 12 m long; force up - up to 50 tons, down - up to 20 tons.
Thus, the achievement of compactness, simplicity and reliability of the design is ensured by the fact that the drilling rig has a telescopic mast with a double cable (rope) multiplier for the rotator carriage stroke, the crown block is made with two pulleys in one row, and the ropes are misaligned with the axis of the rotator, the mast rests on the ground using a heel with a hinged spherical surface, in addition, the hydraulic hoses are laid in the cable layer (cable chain), which is located along the mast boom close to its front face above the rotator and, Along the crown-block between the pulleys, it passes between the guide rollers of the multiplier cables along the rear edge of the boom and then the mast with fastening on it with the feed to the hydraulic drive. Due to the compactness of the crown block in the transport position, there is no need to rotate the mast in a horizontal plane. The hydraulic cables in the cable chain are located compactly, not protruding beyond the dimensions of the mast, and do not interfere with the drilling manifold.
Hydraulic drilling table 14 with clamping jaws 25 (see Fig. 4) is made of swinging, clamping, universal for both drill and casing. The clamping jaws of the drilling table 14 are designed for clamping the drill and / or casing pipes in the table when conducting STR, as well as axially centering the drill pipes in the table, and are respectively universal large stationary clamping jaws 25 of a triangular shape (shown in Fig. 5), and / or small interchangeable (removable) sponges 25.1 of a triangular shape (shown in Fig. 6), or small interchangeable (removable) sponges 25.2 of a semicircular shape (shown in Fig. 7), and / or universal removable sponges 25.3 in the form of a roller centralizer ( shown in Fig. 8). The drilling table is designed to function separately from the breaker / dokrepitel and contains, depending on the type of pipes used for drilling, universal large stationary sponges 25 of a wedge (triangular) shape (FIG. 5) and / or small interchangeable (removable) sponges 25.1 of a triangular shape (FIG. 6) with the ability to lock the drill pipe in the diameter range with large wedge jaws from 145 to 410 mm, small wedge jaws from 70 to 240 mm and / or removable jaws 25.2 of semicircular shape (Fig. 7) with the ability to grip casing in the preferred way SG diameters ranging from 146 to 377 mm (when necessary it is possible to modify the gripping jaws 25.2 casing and up to 550 mm), and provided the possibility of replacing the removable jaws in accordance with the change in diameter of said tube captured range. For centering the drill pipes along the longitudinal axis, universal removable jaws 25.3 are provided in the table in the form of a roller centralizer (Fig. 8), which are designed to center the pipes in a table with a diameter of 60 to 280 mm. FIG. 6-8 removable jaws 25.1, 25.2, 25.3, respectively, are shown in a separate position from the drill table and 25 positioned coaxially with large stationary jaws. It is clear that in their working condition the removable jaws 25.1, or 25.2, or 25.3 corresponding to the types of pipes used and the technical tasks performed, are fixed in the grip of the universal large stationary jaws 25 of the wedge shape. Unlike the German prototype, where the clamping jaws of the drilling table have an individual semicircular shape for each diameter of the clamped pipes and the clamp is made for the pipe body, the drill pipes are clamped at their declared table with universal stationary clamping jaws 25 of a triangular shape (otherwise called wedge shape "fish tail"), which provides a clamp for any diameter of locks in the working range of pipes (versatility). The casing pipes in the table of the inventive drilling rig are clamped in the table with small replaceable (removable) semicircular jaws 25.2 added to the large stationary jaws for the pipe body of individual pipes for each diameter or the above-mentioned universal stationary jaws for the pipe sleeves.
Thus, the clamping jaws of the drilling table 14 are made in the form of universal large stationary jaws 25 of a triangular (wedge) shape with the possibility of adding to them small removable jaws of a triangular (25.1) or semicircular (25.2) shape in order to secure the locks of drilling and / or casing in the range of diameters from 70 to 550 mm, and the removable universal jaws 25.3 in the form of a roller centralizer are made with the possibility of centering pipes in a table with a diameter of 60 to 280 mm. In addition, in the well-known Italian counterparts, the table is not of a swing type, but a side one and is made in one piece with the straightener, due to which limitations in diameters and the applicable assortment of pipes arise. In the declared drilling rig, the breaker / dock 15 is designed to function separately from the table 14 and is diverted (see FIG. 4), i.e. made with the possibility of discharge from the working area of the table when passing through the table drilling tools, drilling or casing when performing drilling operations, which allows for the allocated breaker / dokrepleitelya to use the table 14 of the swing type, which, in turn, ensures their separate independent operation. The breaker / dokrepitel 15 is made in the form of hydraulic- 6 029885
a pipe wrench for securing and unfastening drill pipes and drilling tools. In addition, a double-acting drilling wrench driven by a hydraulic cylinder (not shown on the drawings) can be used to attach / unfasten casing pipes. The execution of the table 14 oar type allows you to pass through him drilling tools and casing of large diameter (up to 1000 mm). Thus, the implementation of the technical solution in the form of a combination of the separate operation of the swing-type table 14 and separately of the diverter-type raskrepitel / dokrepitel 15 allows to ensure the functional versatility of the drilling rig in terms of using a wide range of drill pipes and tools and casing in wide ranges of their shapes and diameters.
The rotator 9 (figs. 1-4, 10-14) of the drilling rig includes hydraulic motors mounted on the rotator case, driving the rotator spindle through replaceable planetary gearboxes and / or transition inserts with couplings and gearing, in accordance with the specified drive gear ratio the rotator is made inclined with the possibility of screwing the upper thread of the drill or casing 26 on the spindle 27 of the rotator in the lower inclined position of the carriage stroke
11 rotators on the mast.
The spindle 27 of the rotator extends from the lower part of the rotator housing and is intended for screwing the upper thread 28 of the pipe 26 and transmitting the rotation to the drill string (Fig. 4). At the same time, the rotator is fixed on the movable carriage in such a way that the axis 22 of the rotator is oriented console with respect to the axes of the ropes.
The rotator is made with the possibility of replacing the gearboxes with other gearboxes and / or transitional inserts with couplings in accordance with a given gear ratio for driving from each of the motors to the rotator spindle.
The rotator 9 can be made in one of the versions depending on the rotational speed and torque by replacing the planetary gearbox with a similar gearbox, but with a different gear ratio, or by replacing the planetary gearbox with a transitional insert with a clutch from the hydraulic drive to the rotator. Execution options have different ranges of rotational speed and torque of the rotator, designed for different types of drilling.
The pipe unit (Fig. 9) is designed for transporting, storing drill pipes and tools and working with them in the well, as well as for transporting the feeder, regiments of the driller's assistant and other interchangeable and assembly parts. The tube unit is placed separately from the chassis 1 of the tractor and may be in a transport position assembled on a trailer or in an unfolded operating position in which it is represented in FIG. 9. The pipe unit includes a subframe 29 with racks for pipes, folding shelves 30 with fencing and ladders, mechanical outriggers 31, a warehouse of 32 pipes, goats 33, a feeder 34 BT and OT, a manipulator 35 with a pipe grip 36 for feeding / draining pipes to the mouth wells. FIG. 9, the manipulator 35 is in the gripping / feeding position of the six-meter pipe on the feed 34.
A drilling rig including a drilling block and a pipe block in their joint operating position is shown in FIG. 10. At the same time, the installation mechanisms are presented in the state when the six-meter pipe to the rotator 9 is gripping / feeding by the feeder 34.
The feeder serves to feed / retract the drill or casing to the wellhead from the goats 33 and bring it to the rotator.
The feeder 34 has a frame structure (Fig. 11, 12), based on the frame 37 of the sections with two guide beams 38, mainly channels. On the frame from the mouth of the working well placed lifting lever 39 with a swinging clamp 40, which is connected to the plunger 41, and the mobile truck 42 is configured to move along the guide beams 38. In addition, additional sections 43 belong to the feeder kit (Fig. 12) for increasing the length of the feeder from 6 to 9 m and up to 12, 13 m in cases of drilling pipes up to 9 m long (and even 12 m) and casing pipes up to 12, 13 m long. In FIG. 11 schematically shows the structure of the feeder, and the mechanisms of the installation, and in particular the feeder, are presented in a state where, after supplying the six-meter pipe 26 to the rotator, the upper thread 28 of the drill or casing pipe 26 is screwed onto the rotator spindle 27 in the lower position of the rotator carriage 11 on the mast . FIG.
12 shows the position of the mechanisms of the feeder when applying a nine-meter drill pipe with an additional section 43 of the feeder 34.
Thus, the drill boring and casing pipe includes a frame consisting of sections with two guide beams with the possibility of adding additional sections to increase the length of the feeder and to enable it to work with drill pipes up to 12 m long and casing pipes up to 13 m long the frame is placed lifting lever with clamp and pusher, made with the possibility of supplying the upper end of the pipe to the spindle of the rotator when it is in the lower inclined position of the rotator on the mast, and the movable carriage with the ability to move along the guide beams of the lower end of the pipe placed on the trolley, when the upper thread of the pipe is screwed onto the rotator spindle, while the plunger provides coaxial feeding of the pipe to the spindle.
Due to the presence of the manipulator 35 and the 34 drill and
- 7 029885
casing lever 39 with a clamp 40 and a pusher 41, as well as a movable carriage 42 as part of a tubular block of the inventive drilling rig, the possibility of complete mechanization of tripping and their implementation on the “no-hand” principle is achieved, which ensures a reduction in labor and economic costs during well drilling and increased security.
Tripping operations with drilling and casing pipes 26 using the equipment of the mast 7, the rotator 9 and the feeder 34 in the working position of the drilling rig are carried out as follows.
The descent of the drill string into the well.
The hydraulic manipulator 35 of the feeder 34 with a pipe grip 36 moves the pipe from the goats 33, where the pipes at the stage of preparation for drilling are preloaded by the manipulator from the warehouse 32 pipes on the pipe trailer, to the guide rails 38 of the feeder 34 WT and OT (see Fig. 9, where the manipulator 35 is in the position of gripping / feeding the six-meter pipe on the feeder). Further, the upper-threaded part of the pipe, placed in the clamp 40, rises with the help of the hydraulic lever 39 from an inclined horizontal position, and the lower-threaded part of the pipe, placed in the carriage 41, can be moved along the guide beams 38 (channels) at a distance from wellhead end of the feeder. Thus, the conveyor captures / feeds the pipe to the rotator 9 (see FIG. 10). At the same time, the rotator 9 is brought to the lower extreme position on the boom and is deflected (because it is made oblique), while the rotator spindle is placed coaxially with the pipe 26 raised on the feeder (see Fig. 11). After that, the spindle rotates the upper thread 28 of the drill pipe 26 onto the rotator spindle 27, the clamp 40 located at the end of the hydraulic lever 39 holding the upper thread part placed in it, and using the push rod 41 coaxially feeding the pipe to the spindle. The pusher 41 is a clamping device in any of the possible variants of its execution - a hydraulic or pneumatic cylinder, a mechanical (for example, spring) clamping mechanism, which provides a clamping force coaxially with the pipe and the spindle in the direction of the latter.
Further, as shown in FIG. 13, the six-meter pipe is lifted from its upper end fixed in the rotator when the carriage 11, moving by means of a hydraulic actuator, lifts up the mast the rotator 9 together with the pipe, which at the same time tends to align with the center of the wellhead, while the manipulator 35 of the pipe feeder 34 is returned to the position to grip the next drill or casing pipe from the goats 33 to feed it to the bed (guides) 38 of the feeder. After the pipe 26 is placed coaxially with the center of the wellhead, the lower thread of the pipe is screwed in as shown in FIG. 14. If necessary, the lower threaded joint is fastened with a breaker 15, then the upper threaded joint is fastened with the spindle retained on the rotator brake. After that, the string of drill pipe is lowered into the well.
The lifting of the drill string from the well is carried out in reverse order. First, the straightener 15 clears the upper thread of the drill pipe 26 at the junction with the spindle 27 of the rotator 9, after which it is screwed back using only the rotator. Then the drill pipe is lifted from the well. In the table 14 is clamped coupling lower lock, and the straightener 15 is made fastening the thread with the capture of the nipple lock. After that, the rotator is unscrewing the lower thread with simultaneous feeding of the rotator 9 with the pipe 26 upwards. Then the rotator is deflected, and the pipe, if necessary (if it is weighted), is installed at one end on the carriage 42 and the other end is lowered onto the clamp 40 of the pipe feeder 34, which is previously coaxially fed to the rotator spindle 27 by means of a hydraulic lever 39. In this case, the cart 42 moves freely along the guides of the beams 38 of the pipe feeder 34, and the rotator tilts in proportion to the descent of the pipe either spontaneously - in the case of a weighted drill pipe, or forcibly using a hydraulic actuator - in the case of a conventional drill pipe. After the pipe reaches its extreme lower position and lies one of the ends in the clamp 40, the upper thread lock coupling 28 is clamped last and unscrewed by the rotator 9 while the pipe 26 is simultaneously fed from the spindle 27 by the push rod 41 of the pipe feeder 34. Then the lever 39 of the feeder is lowered along with the clamped pipe, and the clamp 40 is released from the grip of the pipe. The manipulator 35 carries the pipe to the goats 33 or further to the pipe storage 32 of the trailer for the pipe block.
Tripping operations with casing pipes are carried out using a hook suspended on the rotator spindle (not shown) in the usual way in conjunction with casing elevator or threaded head or clamps, bails or pins and a clamping table, or with an open table in case of large pipes diameter with their installation at the wellhead. In this case, the feeder is used without lifting the lever with the clamp and the pusher, only with the operation of the trolley and the manipulator for feeding casing to the wellhead. In this case, when using threaded casing for screwing / unscrewing threads, a rotator with a threaded head can be used, and for attaching / unscrewing threads an additional conventional suspended drilling wrench driven by a double-acting hydraulic cylinder.
The descent and lifting of the carriage 11 with the rotator 9 is performed using a drive system with a cable multiplier from the main hydraulic cylinder, which moves the telescopic boom
- 8 029885
masts 7 with crown block. The hydraulic system of the drilling rig provides the supply and rotation of the drilling tool in various modes of tripping and drilling with a smooth adjustment of the speed, limiting the maximum allowable torque, effort and feed speed up and down, automatically maintaining a constant axial load on the bit. At the same time, the design of a hydraulic drilling table, a straightener / dock driver, a feeder together allow the use of drilling and casing pipes of any gauge (German, Italian,, GOST, etc.), while analogue drilling rigs are limited to using only their specific drill pipes.
The BT and OT feeder together with the pipe block manipulator allows performing the operation of screwing the upper thread of the drill pipes in the lower position of the rotator and making openworking on the “no-hand” principle conveniently, quickly, safely. In addition, the feeder is made universal in length for BT and OT up to 13 m and differs from the prototype in a more compact design solution.
