The present proposed invention relates to the field of deep drilling, in particular represents one of the types of oilfield equipment is a mobile unit for overhaul and rotary drilling of oil and gas wells.

Known units for workover and drilling oil and gas wells, including two movable block: the block - hoist transport vehicle to a base of the driving motor, winch, transmission and telescopic derrick and block the drilling platform, the platform above the platform unit-lift. Block the drilling platform is equipped with a rotor, candlesticks and foster walkways with shelving (see, for example, the directory companies IRI international Corporation (USA) in 1990, p.5-6, 100 - and 125-ton units for repair oil and gas wells, as well as the company's catalog Industrial export import (Romania) "Oilfield Equipment", str-4775, brand R-80).

The famous design of the unit with the rotor with single-stage bevel gear with ball bearings located below the large gear rigidly associated with a table of the rotor. The design also includes a horizontal drive shaft, chain transmission, connecting the transmission to the platform blocks-lift with intermediate support on the platform of the drilling unit base and shaft connecting the decree is nnow the intermediate support to the drive shaft of the rotor (see, for example, the book Rasarnava "Drilling machines and complexes", M: "Nedra", 1988, p.102-103, as well as the book "the Drilling rig BAV. Technical description and operating instructions", M: "Kolos", 1976, page 7, 12, 37).

The disadvantage of this design is that it requires an additional intermediate bearing for the drive of the rotor, which is the only possible place for the installation of stationary drilling key, so as to install the key on the side of the rotor are restricted transport of the envelope across the width of the base. In addition, the rotor with conical main gear and the necessary diameter of the bore hole has considerable dimensions in width and height and considerable weight.

Also known unit with hydraulic rotor (see, for example, the book "parts Catalogue of the unit for development and repair of wells, Westergeest, ed. No. M, p.40).

The rotor Assembly has a two-stage cylindrical transmission from the hydraulic motor to the table of the rotor, mounted on tandem angular contact roller bearing located between the table and the main gear. In pass-through hole Desk mounted wedge grip (spider).

The main disadvantage of this design is the inability to perform the penetration hole size required due to the placement of the bearing between the table and the gear. In addition, the presence of one bearing with a very small axial base does not provide sufficient resource, as evidenced by the practice of application of such rotors.

In addition, all of the above design is almost impossible to transform in order to apply different types of actuators. The specificity of mobile repair and drilling units is as follows:

1. Limiting the width of the main platform base transport dimensions (2500...2800 mm) and the inability to place the power equipment on the hinged platforms.

2. Different variations of elevations platform block-lift and the platform base Assembly under different conditions:

- with a small difference, for example, when a major overhaul of the well when working with or without preventer, or with one preventer, it is advisable to use a rotor of a traditional design with a horizontal drive shaft;

- when large differences in elevations and the use of stationary drilling key when there is no space for intermediate support, it is advisable to use a rotor with a cylindrical main gear and connecting the drive of the propeller shaft from the platform unit-lift to the vertical shaft of the rotor from the bottom or the use of hydraulic drive rotor (however, sometimes for some reasons related to lack what ewnetu a hydro plant or the undesirability of the location of the hydraulic motors directly on the rotor, application of hydraulic impractical. But the use of a hydraulic drive, in addition to simplifying the transmission unit, sometimes caused by the necessity of maneuvering power and speed, as well as quick reversal.

Among the above structures analogues there is no universal design repair of the drilling rig that meets the above conditions, including conditions of minimum dimensions in width and height, the minimum mass at a sufficiently large diameter bore hole of the rotor, ensure the application of the embedded V-grip for working with drill pipes and casings, designed for the most complex structures of the wells within the capacity of the unit.

For the prototype of the proposed technical solutions can be adopted to repair the drilling rig LTO750 firm Cooper (USA), see the directory specified firms for 1993, page 3 (Appendix I).

Repair the drilling rig of this firm includes a wheeled vehicle base on the platform hosts rig, drilling rig winch and transmission drive drawworks and rotary table. The rotor with built-in wedge grip placed on a separate mobile base and includes a table of the rotor and the main gear rigidly mounted thereon. Transmission rotor includes a horizontal shaft with chain transmission and Premiata the Noi support. This transmission is not universal, more complex; however, it does not leave space to accommodate a stationary drilling key consideration limitations of the transport dimensions of the mobile unit, i.e. it has all the disadvantages of the above analogs.

The main technical task, which directed the present proposed invention is to eliminate the above disadvantages and to create a mobile repair of the drilling rig with universal-drive compact rotor design which would provide the drive capability of the rotor as by means of a horizontal drive shaft, and by supplying power from below without intermediate support, and the ability to use hydraulic rotor, and the design of the unit must be easily transformed in order to apply different types of drive.

To solve the problem of mobile repair the drilling rig includes a transport base on the drilling rig, drilling rig winch and transmission drive drawworks and a rotor, the rotor with built-in wedge engagement, placed on a separate mobile base and including a table of the rotor and the main gear rigidly mounted thereon. The main gear of the rotor is cylindrical and placed between two angular contact terminal connection or lead is the space inside the table of the rotor, equipped with a replaceable and removable drive console, placed in a separate housing, rigidly fastened to the housing of the table of the rotor and comprising a cylindrical satellite, and drive gear mounted on the drive shaft. The output end of the drive shaft removed through the lower part of the body specified drive attachment for mating with the transmission of the drive rotor.

The drive shaft is provided with an additional gear for engagement with the gears of the hydraulic motors. The drive shaft is provided with a first bevel gear for meshing with a second bevel gear, the shaft of which is gated through the rear part of the housing of the specified attachment for connection with the transmission of the drive rotor.

Technical features of the proposed mobile repair of the drilling rig can be implemented using tools used in General engineering (drive console, cylindrical gears, bevel gears etc). Distinguishing features disclosed in the claims, is necessary and sufficient for its implementation, as they provide a solution to the above technical problem is to create a mobile repair of the drilling rig with universal-drive small-sized rotor. The design of the unit must be easily transformed in order to apply different types of p is the water.

In the future the present the invention is illustrated by the example of its implementation is shown diagrammatically on the accompanying drawings, in which:

figure 1 - General view mobile repair of the drilling rig in expanded form, including the block-hoist and mobile base with the rotor and the candlestick;

figure 2 is a longitudinal section of the rotor mobile repair of the drilling rig shown in figure 1, with a vertical drive shaft;

figure 3 is a view in plan of the rotor shown in figure 2;

4 is a cross section of the rotor with hydraulic drive (I-I, figure 3);

5 is a longitudinal section of the rotor with a horizontal drive shaft.

Mobile repair and drilling rig (1) includes unit-lift 1 and the mobile base 2 with the rotor 3 and the candlestick 4. Transport base unit-lift is the chassis 5 with deck engine 6 which is used for transportation purposes, and the drive motor unit. The block-hoist 1 includes oil rig 7, for example, telescopic type, shown in figure 1 in the horizontal (transport)and vertical (working) position, drilling rig winch with drilling 8 and tartaglini 9 reels and the transmission 10, which is designed to drive the drilling and hartalega winch drums and rotor 3. Rotary transmission consists of two sections, a horizontal propeller shaft 11,the angle of the reversing gear 12 and the vertical (or with a slight deviation from the vertical) of the propeller shaft 13. Mobile base 2 is mounted on the trailer 14. It has articulated roaming Central frame 15, on which is mounted a stationary drill key 16. The rotor 3 is in the Central recess of the frame 15 so that his Desk is flush with the floor of the drilling platform 17.

The rotor 3 with a built-in wedge grip 18 (figure 2) includes the table 19 and the main gear 20 fixed on him. The main gear of the rotor 20 is cylindrical and is placed between the two angular contact bearings 21 and 22 inside the housing 23 table of the rotor 19.

The rotor 3 is equipped with a replaceable and removable drive console 24 (Fig 3). This console is placed in a separate housing 25. Console 24 is rigidly by bolts 26 are fastened with the housing 23 table of the rotor. Console 24 includes a cylindrical satellite, 27, not mounted stationary axle 28 by means of bearings 29 (2) and drive the bevel gear 30 is mounted on the drive shaft 31 mounted in bearings 32, 33. The output end of the drive shaft 31 may be removed through the bottom of the housing 25 consoles 24 and to bear slotted flange 34 for mating with the drive shaft 13 (figure 1). In addition, the drive shaft may be provided with an additional cylindrical gear 35 (figure 4) instead of the spacer sleeve 36 for engagement with the gear 37 of the hydraulic motors 38 (figure 4). In this is case, the drive shaft 31 is shortened, and the place of exit from the housing 25 is closed by a plug 39. The drive shaft 31 may also be provided with a first bevel gear 40 (figure 5), to be installed instead of the spacers 36 for engagement with a second bevel gear 41, a shaft 42 which is gated through the rear end part of the housing 25 consoles 24 and carries a flange 43 for connection with the horizontal drive shaft (not shown).

The V-grip 18 (figure 2, 3, 5) are shown when working with a casing and drill pipes 44 (right side of figure 2) or with a leading drill pipe 45 and the clamp 46 (left side of figure 2).

The work of the claimed repair of the drilling rig is as follows.

In the case of the drive of the rotor 3 from the mechanical transmission unit-lift 1 the torque is transmitted from the angular gear 12 by means of a vertical drive shaft 13 on the drive shaft 31 (figure 2) through the flange 34 and then through the drive cylindrical gear 30, 27, main gear 20 table 19 of the rotor and through the clamp 46, the leading pipe 45. In this case, the presence of satellite 27 due to the fact that the drive shaft 13 must be removed from the well to free up space under preventry the block and the groove of the circulation system. Thus, on the rig floor 17 is released the only possible place for stationary drilling of the key 16, the cat who who cannot be installed at the side of the rotor 3 due to the limitations overlay transport dimensions (width) of the mobile base 2 (Fig 1).

In the case of using the hydraulic drive of the rotor 3 from hydrostation 47 (1) transmission of the drive of the rotor 11, the angular gear 12 and shaft 13 are not used, and the rotor are mounted actuators 38 (figure 4), from which the torque is transmitted through gears 37, 35 on the drive shaft 31 through the drive gear 30 and further leading to the pipe 45, as described above (figure 2).

In the case of use in the transmission of the drive rotor 3 traditional chain drive with an additional intermediate support on the rig floor 17 and a horizontal propeller shaft (not shown) in the attachment 24 is mounted a pair of bevel gears 40, 41 (5), the shaft 42 and the flange 43. In this case, the torque is transmitted from the horizontal drive shaft (not shown) through a pair of bevel gears 40, 41 and the drive shaft 31 and forth as described above.

Thus, the claimed design mobile repair the drilling rig has the advantage of universality of the rotor drive type of drive allows the drive rotor by means of a horizontal drive shaft, a drive rotor bottom without intermediate support, and also allows you to place a stationary drill key without exceeding transport dimensions unit width.
