Abstract
The invention relates to the field of oil field oil extraction engineering, and belongs to a bidirectional setting device which can be used for indoor inspection of underground tools such as a bridge plug, an anchor seal integrated soluble ball seat for fracturing and the like. The invention solves the problem that the reset piston part needs to be disassembled after the one-way setting device is used every time. The device consists of a force transmission head (1), a key (2), a lock sleeve (3), a piston rod bushing (4), a piston rod (5), an end joint (6), a piston (7), a piston cylinder (8), a push cylinder (9) and a power fluid connector (10); wherein the force transmission head (1), the piston rod lining cylinder (4) and the piston rod (5) are connected through a key (2). The invention has the advantages of simple structure, safety and reliability, etc., and the piston position does not need to be disassembled and reset after setting.
Description
The technical field is as follows: the invention relates to the field of oil field oil extraction engineering, and belongs to a bidirectional setting device which can be used for indoor inspection of underground tools such as a bridge plug, an anchor seal integrated soluble ball seat for fracturing and the like.
Background art: the one-way setting ware that indoor experiment inspection bridging plug was commonly used at present is inside to have the two-stage piston, and the structure is complicated and only can one-way use, need disassemble after using at every turn with piston part reset, not only wastes time and energy, frequently disassembles moreover and resets the piston and easily causes the damage to setting ware internal seal element, leads to setting ware inefficacy.
The invention content is as follows: the invention aims to provide a bidirectional setting device for indoor inspection of a downhole tool, which is simple in structure and free of disassembling a reset piston component after being used.
The technical scheme of the invention is as follows: the piston mainly comprises a force transmission head, a key, a lock sleeve, a piston rod lining cylinder, a piston rod, an end connector, a piston cylinder, a push cylinder and a power fluid connector; the power transmission head, the piston rod lining cylinder and the piston rod are connected through keys, a through groove is formed in the piston rod lining cylinder, the keys can move up and down in the through groove of the piston rod lining cylinder, the power transmission head is in threaded connection with the lock sleeve, the piston rod lining cylinder is in threaded connection with the end connector, the power liquid connector is welded with the end connector, the piston is in threaded connection with the piston rod, the end connector is in threaded connection with the piston cylinder, the power transmission head is in threaded connection with the push cylinder, and the whole structure is symmetrical up and down by taking the piston as a center.
The invention has the following advantages:
1) compared with a one-way setting device, the one-way setting device is simple in structure, and the safety and the reliability are improved.
2) After the one-way setting device is used, the push cylinder is only required to be disassembled and then is installed on the force transmission head at the other end, and the one-way setting device can be used again, so that the problem that a reset piston part needs to be disassembled after the one-way setting device is used is solved, time and labor are saved, and the service life of the setting device is prolonged.
Description of the drawings: FIG. 1 is a schematic view of the structure of the present invention.
The specific implementation mode is as follows: the invention is further detailed with the attached drawings, and consists of a force transmission head 1, a key 2, a lock sleeve 3, a piston rod bushing 4, a piston rod 5, an end joint 6, a piston 7, a piston cylinder 8, a push cylinder 9 and a power fluid connector 10; wherein the power transmission head 1, the piston rod lining cylinder 4 and the piston rod 5 are connected through a key 2, a through groove 11 is formed in the piston rod lining cylinder 4, the key 2 can move up and down in the through groove 11 of the piston rod lining cylinder 4, the power transmission head 1 is in threaded connection with the lock sleeve 3, the piston rod lining cylinder 4 is in threaded connection with the end connector 6, the power liquid connector 10 is welded with the end connector 6, the piston 7 is in threaded connection with the piston rod 5, the end connector 6 is in threaded connection with the piston cylinder 8, the power transmission head 1 is in threaded connection with the push cylinder 9, and the whole structure is symmetrical up and down by taking the piston 7 as the center.
When the bridge plug is set in an indoor experiment, the push cylinder 9 is arranged on the force transmission head 1 at one end of the piston rod lining cylinder 4 which is completely extended out, and the bridge plug to be tested is arranged on the piston lining cylinder 4 at the same end. When setting, a hydraulic power equipment pipeline is connected to the power liquid connector 10 at the far end, and the piston 7 and the piston rod 5 are pushed to move by hydraulic pressure. Meanwhile, under the drive of the key 2, the force transmission head 1, the lock sleeve 3 and the push cylinder 9 move synchronously, and the push cylinder 9 pushes the bridge plug to seat. After setting, the push cylinder 9 is detached and installed on the other end force transmission head 1, and a hydraulic power equipment pipeline is connected to the other end power fluid connector 10, so that next bridge plug test can be completed.
