Description

Technical Field

[0002] When it is necessary to exploit the oil and gas buried in the rock formation, because the oil and gas are usually dispersed in the cracks of the rock formation, the existing technology for exploiting the oil and gas in the rock formation usually uses deep hole hydraulic fracturing technology.

[0003] The relevant hydraulic fracturing technology generally uses a bag-type sealer, which is achieved by installing bags on the upper and lower sides of the circulation pipe, moving the circulation pipe and the bag into the deep hole, and then pouring mortar into the two bags and the area between the two bags to make the bags fit the inner wall of the deep hole, so that the mortar is retained inside the deep hole, thereby completing the sealing operation of the deep hole entrance area. However, in the process of adding mortar into the deep hole, the mortar must first be allowed to enter the bag so that the bag expands and fits tightly against the inner wall of the deep hole. The surface of the deep hole is relatively flat. When adding mortar between the two bags, the bag and the inner wall of the deep hole are not closely fitted, which can easily cause the mortar to leak from the gap between the bag and the inner wall of the deep hole, affecting the sealing effect of the deep hole and increasing the amount of mortar used.

The sliding cylinder is used to enter the borehole, the sealer conveying assembly is used to convey the sealer, and the rotating slotting mechanism is used to follow the sliding cylinder to move into the borehole to process and slot the inner wall of the borehole, so that a better sealing effect can be obtained between the borehole and the sealer. The sliding mechanism is used to adjust the position of the sliding cylinder and the sealer conveying assembly relative to the lifting mechanism to change the horizontal position so that it can enter the borehole more accurately. When sealing the borehole before the hydraulic fracturing operation, first move the sliding cylinder to the sealer position in the borehole, and adjust the position of the two rotating slotting assemblies to rotate the friction disk in the borehole.

[0033] The deep hole hydraulic fracturing sealer pushing device according to the embodiment of the present invention has the advantage of changing the shape of the hole wall to improve the sealing effect.

[0034] In some embodiments, the sliding mechanism includes a sliding sleeve, a sliding plate body and a first electric cylinder. The sliding sleeve is connected to the top of the lifting frame. At least part of the sliding plate body enters the sliding sleeve and is slidably connected to the sliding sleeve. The first electric cylinder is located on the sliding sleeve. The output end of the first electric cylinder is connected to the sliding plate body to drive the sliding plate body to move relative to the sliding sleeve.

[0035] Specifically, the sliding sleeve is slidably connected to the sliding plate so that the sliding plate can move relative to the lifting frame. The first electric cylinder is used as a linear drive mechanism to drive the sliding plate to perform linear reciprocating motion relative to the lifting frame. The sliding mechanism is arranged on both sides of the lifting frame to respectively drive the sliding cylinder and the hole sealer conveying assembly to move.

[0036] In some embodiments, the deep hole hydraulic fracturing sealer pushing device also includes a traction mechanism, the traction mechanism includes a traction wheel, a winding drum, a rotating frame and a first motor, guide slots are respectively arranged on the sliding sleeve and the sliding plate, the traction wheel is located in the guide slot and is rotatably connected to the guide slot, the winding drum is connected to the lifting frame through a rotating seat, the output end of the first motor is transmission-connected to the winding drum, the rotating frame is located at the first end of the sliding cylinder, and a rotating block is pivotally connected to the rotating frame, and the traction rope wrapped around the winding drum is connected to the rotating block after passing through multiple guide slots.

[0037] Specifically, the traction mechanism is arranged on the sliding mechanism to drive the sliding cylinder below to enter the drill hole. The guide groove is used to install the traction wheel, the traction wheel is used to support the traction rope, and the traction wheel can also be used to change the moving direction of the traction rope. The first motor drives the winding drum to rotate. As the winding drum rotates, the traction rope is wound around the winding drum to complete the lifting of the sliding cylinder. The winding drum rotates in the opposite direction, and the winding drum releases the traction rope to complete the sinking of the sliding cylinder. The rotating block is arranged at the first end of the sliding cylinder to fix the traction rope.

[0039] Specifically, the partition cylinder is arranged inside the sliding cylinder, and the two cylinders are respectively provided with slide grooves, and the bidirectional screw is arranged inside the partition cylinder. The second motor drives the bidirectional screw to rotate, and the sliding seats at both ends of the bidirectional screw move toward and away from each other with the forward rotation and reverse rotation of the second motor, thereby completing the position adjustment of the sliding seat. The two sealing belts are brought close to each other through the magnetic adsorption between the magnetic strip and the ferrous strip to achieve the seal between the two sealing belts. When the two sliding seats move between the sliding cylinder and the partition cylinder, the positions of the two slide grooves do not correspond, which can prevent the sand generated during drilling from entering the partition cylinder. When the sliding seat moves, it is between the two sealing belts. As the two sliding seats move, the corresponding areas of the two sealing belts are separated. After the sliding seat moves out of the corresponding area, the two sealing strips are kept in close contact and sealed again under magnetic adsorption, which can prevent the sand from entering the partition cylinder.

[0040] In some embodiments, the rotating grooving mechanism includes a rotating cylinder, a rotating sleeve, a conical internal tooth groove, a third motor and a friction plate. The rotating cylinder is connected to the sliding seat, the rotating ring sleeve is located in the rotating cylinder and is rotatably connected to the rotating cylinder, the conical internal tooth groove is located at the bottom of the rotating ring sleeve, the output end of the third motor is connected to the bevel gear, and the friction plate is located on the rotating ring sleeve.

[0041] Specifically, the rotating slotting mechanism is used to slot the inner wall of the borehole. The rotating cylinder is fixedly connected to the sliding seat, and thus follows the sliding seat to move up and down along the sliding cylinder. The rotating ring is rotatably connected to the rotating cylinder. The conical inner tooth groove at the bottom of the rotating ring is used to cooperate with the bevel gear. As the bevel gear rotates, the rotating ring is driven to rotate. The third motor is used to drive the bevel gear to rotate. The friction disk is fixedly connected to the rotating ring.

The fixed cylinder is arranged on both sides of the first end of the sliding cylinder, at least part of the bending sliding member is located in the fixed cylinder and is slidably connected to the fixed cylinder, and the scissors-type lifting structure is located in the fixed cylinder and is connected to the bending sliding member.

[0043] Specifically, the fixed telescopic structure is used to make the sliding cylinder descend in the drill hole, the fixed cylinder is fixed on both sides of the top of the sliding cylinder, the fixed cylinder is slotted for the bending sliding member to slide inside, the bending sliding member is connected to the fixed cylinder through a scissor lift structure, the scissor lift structure is connected by a plurality of scissor structures, and as the scissor structures are deformed, the bending sliding member is pushed to move relative to the fixed cylinder. A fixed groove is provided on the fixed support plate, and the fixed handle is connected to the bending sliding member, so that the fixed support plate can move with the bending sliding member.

[0044] In some embodiments, the deep hole hydraulic fracturing sealer pushing device also includes a fixed offset structure, which includes a rotating ring seat, a mounting frame, a support ring, an engaging sleeve, a movable screw and a pushing body.

The bottom of the fixed support disc is fixedly connected to the mounting frame, and multiple mounting frames are evenly distributed along the circumferential direction of the fixed support disc with the center of the fixed support disc as the center. The bottom of the mounting frame is arranged with a universal wheel to facilitate the movement of the fixed support disc. The meshing sleeve is fixedly connected to the support ring through a bracket, and the threaded sleeve is arranged on the meshing sleeve. A pushing groove body is arranged on each mounting frame, and the pushing body is fixedly connected to the moving screw rod. As the threaded sleeve rotates, 54 drives the gear 56 to rotate, and the gear 56 and the meshing sleeve are meshed and drive the meshing sleeve to rotate. As the meshing sleeve rotates, the threaded sleeve drives the moving screw rod to move relative to the meshing sleeve, and then drives the pushing body to move toward the pushing groove body. The pushing body drives the mounting frame to move, and the fixed support disc thereby drives the sliding cylinder to deviate, and the friction disc is processed to form a groove in the corresponding area. When the rotating cylinder body is subsequently moved longitudinally, grooves can be processed in different directions in different areas to increase the contact area between the bladder and the inner wall of the borehole.
