Abstract

The invention relates to deep exploration drilling in small diameter wells and improves the reliability and efficiency of the operation of the machine. For this purpose, the anvil 9 with the pusher (T) 10 installed inside it is placed in the upper part of the first shell (VChK). The rotation mechanism of the rock-destroying tool (PRI) is made in the form of a rod 11 with a return spring 15, connected to the lower part 2 of the housing by a screw connection with the rolling elements 13, ac VCHK - by a coupling 20 of ratchet engagement and by T 10 - by a hydraulic booster 16 with the upper 17 and lower 18 pistons mi. During the operation of the machine, the drummer 6 placed in the VChK strikes the end of T 10, moving it down. Part of the energy of the drummer 6 transmits the anvil 9 when colliding with it and further through the lower part of the 2nd body, having an adapter 14 under the PRI. The movement of T 10 through the hydraulic booster 16 and the coupling 20 is transmitted to the rod 11. The coupling 20 prevents the rotation of the rod 11 relative to the nut-rotor 12. The axial movement of the rod 11 is transformed into a rotary movement with / "// 2 /

Description

The lny movement of the lower part of the body. When the drummer 6 returns to the upper position, the spring 15 returns the elements of the PRE-TRIP mechanism to the initial position. The hydraulic cylinder 16 can be placed in the VCHK, while its piston 17 can interact with the lower end of the T 10, and the piston 18 with the coupling 20. When placing the hydraulic cylinder 16 in the lower part 2 of the housing, its piston 18 is rigidly connected to the flange made on the lower the end of the T 10, and the piston 17 can interact with the rod 11. In this case, between the flange T 10 and the adapter 14 is placed a spring 15. 3 Cp f-ly, 4 ill.

; The invention relates to a drilling technique, namely, submersible hydraulic percussion machines for drilling wells along predetermined routes, and can be used mainly in deep geological exploration drilling for solid minerals in wells of small diameter.

The aim of the invention is to increase the reliability and efficiency of a submersible hydropercussion machine. .

The submersible hydraulic hammer machine includes a housing, the upper part 1 of which is connected to its lower part 2 by means of a rotation assembly mounted on bearings 3.

Inside the upper part 1 of the housing, there is a direct-acting hydropercussion mechanism, including a valve assembly with valve 4 itself, as well as a piston head 5 with a hammer 6, above which a force spring 7 is placed, one end of which is fixed on the hammer 6, and the other connected to the housing of the upper part 1, in which the spline connection 8 was made in the latter for launching the hydraulic shock machine.

full protruding in the direction of the drummer 6.

In the lower part 2 of the machine body there is a rotation mechanism of the rock-breaking tool, executed in the form of a rod 11 mounted for axial movement, connected by a screw connection with a nut-rotor 12 of the lower part 2 of the body, interacting with each other through rolling bodies 13 (for example, rollers), and the centering adapter 14 for the rock-breaking tool, on which the return spring 15 is placed. The adapter 14 is connected to the nut-rotor 12. The hydraulic booster 16, which includes the hydraulic cylinder, the upper and lower pistons 17 and 18, can be entered both in the upper 1 and in the lower 2 parts of the split housing of the hydropercussion machine.

The upper part 1 of the split housing of the machine is connected to the drill string by means of a centering adapter 19.

In the embodiment of the device with the hydraulic amplifier, in the upper part 1 of the machine case the pusher 1Q with the lower end rests loosely on the upper piston 17 of the hydraulic booster 16, below the lower piston 18 of which the coupling 20 is located. One end of the turning mechanism rod 11 is in ratchet engagement with the coupling 20, axially movable relative to the anvil 9 by means of a spline joint 21. A return spring 15 is fixed to the second end of the rod 11.

Submersible hydraulic hammer machine works as follows.

With the sharp setting of the machine to the bottom hole spline connection

supported by a Prussian fan 23 (in a compressed state) and having a potential, a piston block 5 with a drummer

blocks flow of flushing fluid. Under the pressure of the resulting hydraulic shock, the valve system 4 - piston-hammer 5 - drummer 6 moves downwards with increasing speed, and the drummer 6 after cutting off valve 4 strikes the protruding upper end of the pusher 10, forcing the latter to axially move downwards, and at the same time compresses the force of the spring 7.

Part of the energy of the drummer 6 transmits the anvil 9 upon further collision with it.

The pusher 10, in turn, forces the piston 17 and 18 of the hydraulic booster 16 to move, causing the axial force multiplication due to the difference of its areas, which is transmitted to the rod 11 through the coupling 20. The coupling 20 provides the axial movement of the rod 11, simultaneously preventing the latter from turning relative to the nut rotor 12. In the mechanism of rotation, the axial movement of the rod 11 30 is converted into rotational movement of the nut-rotor 12 and the associated adapter 14. In this case, the screw rod 11 compresses the return spring 15 ,.

After cutting off and stopping valve 4, the passage for flushing fluid reopens, its pressure drops and after turning the rotor nut 12 with adapter 14, springs 7 and 15 return the system to its original position. In this case, the coupling 20, by means of a ratchet connection with the rod 11, allows the latter to rotate when it returns to its original position.

When a piston-collision 5 meets valve 4, the passage of fluid again closes and the cycle repeats.

In the embodiment of the machine with the placement of the hydraulic booster in the lower part 2 of the casing, the pusher 10 is a pipe, to the lower end of which is a gesture. flange 22 is attached, one side of which rests on a spring

the spline joint 21 relative to the anvil 9.

After the striker 6 strikes a protruding upper end of the pusher 10, the latter moves downwards. With the pusher 10 connected to the flange 22, the lower piston 18 also moves downward and the spring 15 contracts. The released spring 23 expands and, due to its force, moves down in the spline joint 21 a sleeve 20. Lastly, being in ratchet engagement with the pivot 11 of the turning mechanism, it moves it down and simultaneously allows it to turn. Together with the rod 11, the upper piston 17 moves downward. When the striker 6 strikes the anvil 9, part of the impact energy is transmitted to it. After the rebound of the striker 6 from the anvil, the spring 15 expands, forces the pistons 17 and 18 of the hydraulic booster 16 to move upward, while due to the difference in their areas a multiplied axial force is generated, which is transmitted to the screw shaft 11. The coupling 20 provides the axial movement of the latter, preventing turning it relative to the nut-rotor 35 and compressing the spring 23. The axial movement of the rod 11 is converted in the rotation mechanism into a rotational movement of the nut-rotor 12 and the adapter 14 associated with it. 6 rnika anvil cycle is repeated.
