TECHNICAL FIELD

The present disclosure relates to, but is not limited to, mechanical equipment technology, in particular to a horizontal-to-vertical drilling module for a deep well.

BACKGROUND

At present, one type of conventional mechanical borehole wall coring tool uses a hydraulic pump to drive a hydraulic motor which in turn drives a drill bit to drill a core, and another type uses the driving force provided by an electric motor to drive the drill bit to drill a core.

The hydraulic motor and electric motor only provide power for coring operation. To perform the coring operation, a specially designed guide plate is needed to be provided to guide the hydraulic motor or electric motor to carry out the coring operation. The drilling guide plate needs to be developed and designed according to the structure of the hydraulic motor or electric motor, and thus it is difficulty to design and the designed guide plates are substantially different from each other.

The electric motor coring technology uses the electric motor to directly drive the reducer which in turn drives the drill bit to perform coring operation. The rotating pin (equivalent to the moving column in this disclosure) that performs coring action is located on the casing of the reducer body, and the electric motor needs to rotate with it. The produced coring tool needs to have the functions of coring, core breaking, turning, core pushing, etc., which makes its design difficult and has always puzzled those skilled in the art.

However, the technical schemes of the present disclosure may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present disclosure is not limited by the specific embodiments disclosed below.

As shown in FIGS. 1 to 10, the horizontal-to-vertical drilling module for a deep well provided by the present disclosure includes a fixed plate 1, a movable plate 2, a coring module 3 and a moving slider 4. As shown in FIG. 9, the fixed plate 1 is provided with a first guide hole having a turning section 11, a core breaking section 13 and a moving section 12 positioned between the turning section 11 and the core breaking section 13. The movable plate 2 is movably installed on one side of the fixed plate 1, and as shown in FIG. 8, is provided with a second guide hole having a turning driving section 21, a moving driving section 22 and a core breaking driving section 23. The moving driving section 22 is located between the turning driving section 21 and the core breaking driving section 23. The projection of the first guide hole on the movable plate 2 intersects with the second guide hole. The coring module 3 as shown in FIG. 2 is located on the other side of the fixed plate 1, and the side thereof facing the fixed plate 1 is provided with a moving column 31 and a mounting shaft 32. The moving column 31 extends into the second guide hole through the first guide hole. The moving slider 4 as shown in FIG. 10 has an open groove 41 and is installed in the first guide hole and rotatably connected to the mounting shaft 32 of the coring module 3. The moving column 31 can slide into and out of the open groove 41. The coring module 3 can move in the moving section 12 and the core breaking section 13. The turning driving section 21 can drive the moving column 31 to move from the turning section 11 to the moving section 12 and slide into the open groove 41. The turning driving section 21 can also drive the moving column 31 to slide out of the open groove 41 and move from the moving section 12 into the turning section 11. The moving driving section 22 can drive the coring module 3 and the moving column 31 located in the open groove 41 to move together in the moving section 12 and the core breaking section 13. The core breaking driving section 23 can drive the moving column 31 to press the inner wall of the open groove 41 in the core breaking section 13 to perform core breaking.

With respect to the horizontal-to-vertical drilling module for a deep well, the fixed plate 1 is provided with a first guide hole having a turning section 11, a core breaking section 13 and a moving section 12 positioned between the turning section 11 and the core breaking section 13. The movable plate 2 is movably installed on one side of the fixed plate 1, and is provided with a second guide hole having a turning driving section 21, a moving driving section 22 and a core breaking driving section 23. The moving driving section 22 is located between the turning driving section 21 and the core breaking driving section 23. The projection of the first guide hole on the movable plate 2 intersects with the second guide hole. The coring module 3 is located on the other side of the fixed plate 1, and the side thereof facing the fixed plate 1 is provided with a moving column 31. The moving column 31 extends into the second guide hole through the first guide hole. The moving slider 4 is installed in the first guide hole and rotatably connected to the coring module 3. The moving slider 4 is provided with an open groove 41 and the moving column 31 can slide into and out of the open groove 41. The horizontal-to-vertical drilling module for a deep well is simple in structure and can realize the coring, core breaking, turning and core pushing actions, thereby meeting the usage requirement better.

The coring module 3 can move in the moving section 12 and the core breaking section 13, and can move from the moving section 12 into the turning section 11.

Turning action is as follows. The moving slider 4 is located at the end of the moving section 12 adjacent to the turning section 11, and the moving column 31 is located in the open groove 41. By moving the movable plate 2 in a first direction, the turning driving section 21 drives the moving column 31 to slide out of the open groove 41 and move from the moving section 12 into the turning section 11, thus realizing turning the coring module 3 from the vertical state to the horizontal state (The vertical state and the horizontal state are only for better explanations of the present disclosure, and are not mandatory limitations to the present disclosure. The coring module 3 can be in other states, i.e., turned from a first state to a second state, switched from the state shown in FIG. 3 to the state shown in FIG. 4). By moving the movable plate 2 in a direction opposite to the first direction, the turning driving section 21 drives the moving column 31 to move from the turning section 11 to the moving section 12 and slide into the open groove 41, thus turning the coring module 3 from the horizontal state to the vertical state (from the state shown in FIG. 4 to the state shown in FIG. 3).

Moving action (which can be understood in conjunction with FIGS. 3, 7 to 9) is as follows. The moving driving section 22 can drive the coring module 3 and the moving column 31 located in the open groove 41 to move together in the moving section 12 and the core breaking section 13. The moving column 31 and the moving slider 4 can move together from the moving section 12 to the core breaking section 13 (the coring module 3 is in a vertical state), or the moving column 31 and the moving slider 4 can move together from the core breaking section 13 to the moving section 12 (the coring module 3 is in a vertical state).

Core breaking action is as follows. The moving slider 4 is located in the core breaking section 13 (the coring module 3 is in a vertical state), and the moving column 31 is located in the open groove 41. The core breaking driving section 23 drives the moving column 31 to press the inner wall of the open groove 41 in the core breaking section 13 to perform core breaking. The coring module 3 turns slightly (e.g., the set angle can be 3-5 degrees, etc.) about its hinge axis where it is hinged to the moving slider 4, accomplishing the core breaking action (which can be understood with reference to FIGS. 6 and 7).

In addition, as shown in FIGS. 1 and 2, the horizontal-to-vertical drilling module for a deep well further includes a core breaking resetting module 5 installed beside the core breaking section 13 and configured to reset the moving column 31 and the moving slider 4 after core breaking, so as to ensure the use stability of the horizontal-to-vertical drilling module for a deep well and ensure that the horizontal-to-vertical drilling module for a deep well can be continuously used for coring.

As shown in FIGS. 2, 5, 7 and 9, the core breaking resetting module 5 may include a movable beam 51 and a resetting member 52. The fixed plate 1 is further provided with a third guide hole 14 communicated with the core breaking section 13, and the movable beam 51 is movably installed in the third guide hole 14. The end of the movable beam 51 remote from the core breaking section 13 is connected to the resetting member 52. The resetting member 52 is configured to reset the moving slider 4 and the moving column 31 to a vertical state so that they are able to smoothly move from the core breaking section 13 into the moving section 12 in subsequent actions. The movable beam 51 is pressed against the outer bottom surface 410 of the open groove 41 when the moving slider 4 is positioned in the core breaking section 13.

Specifically, as shown in FIGS. 2, 5, 5a and 5b, the resetting member 52 includes a positioning block 521, a piston 522, an elastic resetting piece 523, and a blocking piece 524. The positioning block 521 is fixedly connected with the fixed plate 1, and is provided with a piston cavity and a mounting cavity communicated with each other. The mounting cavity has an opening facing the movable beam 51. The piston 522 is movably installed in the piston cavity in a sealed and position constrained manner. The elastic resetting piece 523 is installed in the mounting cavity. The blocking piece 524 is movably installed in the opening of the mounting cavity in a sealed and position constrained manner and presses tightly against the elastic resetting piece 523. The movable beam 51 is connected to the blocking piece. The piston cavity and the mounting cavity are filled with hydraulic oil. During core breaking, the moving slider 4 pushes the blocking piece 524 to move toward the inside of the mounting cavity through the movable beam 51, and the piston 522 moves toward the outside of the piston cavity. When the core breaking force exerted by the movable plate 2 is removed, the elastic resetting piece 523 pushes the blocking piece 524 toward the outside of the mounting cavity, and the blocking piece 524 pushes the moving slider 4 to rotate to a vertical state (i.e., a state in which core breaking is not performed) through the movable beam 51, meanwhile the piston 522 moves toward the inside of the piston cavity. Such structure can prevent the positioning block from being crushed under the external environment high pressure. The elastic resetting piece 523 may be any one of a disc spring and equivalent components thereof.

In order to better realize the turning of the coring module 3 from the vertical state to the horizontal state, as shown in FIGS. 5 and 8, the side of the movable plate 2 facing the fixed plate 1 is provided with a position constraining part 24. The position constraining part 24 is located at the end of the turning driving section 21 adjacent to the core breaking section 13, and the moving slider 4 is provided with a matching part. The open groove 41 is directly communicated with the turning section 11. The moving slider 4 is located at the end of the moving section 12 away from the core breaking section 13. When the turning driving section 21 drives the moving column 31 to slide out of the open groove 41 and move from the moving section 12 into the turning section 11, the matching part presses against the position constraining part 24. When the turning driving section 21 pushes the moving column 31 into the turning section 11, a component force toward the core breaking section 13 will be generated, and the position constraining part 24 prevents the moving slider 4 from moving along the moving section 12 toward the core breaking section 13. The position constraining part 24 is a position constraining boss and the matching part is a matching boss.

In an exemplary embodiment, as shown in FIG. 9, the first guide hole includes a vertically arranged first elongated hole and an arc-shaped hole located on the right side of the first elongated hole. The left end of the arc-shaped hole is communicated with the right side of the first elongated hole. The moving section 12 and the core breaking section 13 form the first elongated hole. The moving section 12 is located above the core breaking section 13, and the turning section 11 is located on the arc-shaped hole. The moving slider 4 is rotatably installed at the lower end thereof on the coring module 3, at the upper end thereof has an open groove 41 opened toward the right side. When the moving slider 4 moves to the upper end of the first elongated hole, the open groove 41 is communicated with the arc-shaped hole, and the center of the arc-shaped hole is located at the position where the moving slider 4 and the coring module 3 are rotatably connected, so that the moving column 31 moves into the arc-shaped hole around the position where the moving slider 4 and the coring module 3 are rotatably connected. The third guide hole 14 is arranged as a fourth elongated hole, and the right end of the fourth elongated hole is communicated with the left lower part of the first elongated hole.

In addition, as shown in FIG. 8, the second guide hole includes a second elongated hole extending obliquely upward from right to left and a third elongated hole extending obliquely upward from left to right. The upper end of the second elongated hole is communicated with the upper end of the third elongated hole. The moving driving section 22 is the second elongated hole, the core breaking driving section 23 is the right end hole wall of the second elongated hole, and the turning driving section 21 is the third elongated hole. The first direction is from left to right, and the direction opposite to the first direction is from right to left.

Furthermore, as shown in FIG. 8, a turning positioning section 25 is transversely extended from the left end of the third elongated hole towards the left. When the moving column 31 moves to the end of the turning section 11 remote from the moving section 12, the moving column 31 is also located in the turning positioning section 25, which ensures that the coring module 3 maintains in a horizontal state and smoothly pushes the core.

As shown in FIGS. 2 and 8, the fixed plate 1 is provided with a guide rail groove 15 arranged along the left-right direction, and the movable plate 2 is provided with a guide rail 26 arranged along the left-right direction. The guide rail 26 is movably installed in the guide rail groove 15 and can move in the left-right direction in the guide rail groove 15.

As shown in FIG. 1 and FIG. 2, each of the movable plate 2, the fixed plate 1, the moving slider 4 and the moving column 31 is arranged in each of two groups symmetrically arranged at the front and back sides of the coring module 3. The two fixed plates 1 are fixedly connected through a first cross beam 61, the two movable plates 2 are fixedly connected through a second cross beam 62, and the movable beam 51 is a U-shaped beam.

The movable plate 2 is driven by a linear driving component which can be any one of a hydraulic cylinder and equivalent structure thereof, all of which can achieve the purpose of the present disclosure and do not depart from the design idea of the present disclosure, therefore they are not repeatedly described herein, and should be within the protection scope of the present disclosure.
