Abstract
The utility model discloses a hydraulic connecting-tripping device, which comprises a coupling, a connecting pipe, an upper joint, a sealing element, a spring ring, a lock block, a shear pin, a lock sleeve and a lower joint. The utility model is characterized in that one end of the upper joint is connected with the connecting pipe, and the other end is fixed to the lower joint; a spacing sleeve is connected to the outside of the upper part of the hydraulic connecting-tripping device, and the lower part is provided with the lock sleeve; the lock block is arranged between the lock sleeve and the lower joint. The utility model adopts ground hydraulic control and needs no pipe string to provide any load, which realizes safe connection and tripping; in addition, a lock block locking mechanism is adopted. The utility model, which has the advantages of connecting-tripping reliability, high successful rate and stable performance, the advantages that the accident that midway shedding during operation does not easily occur, hydraulic pipelines can be connected in series with other in-silo hydraulically controlled tools to be used, etc., is used in oil production technology for an oil field.
Description
One, technical field:
The utility model relates to oil exploitation down-hole seam change switch, particularly a kind of hydraulic pressure on-off connector.
Two, background technology:
Existing a kind of on-off connector is mechanical reverse buckling type structure, and it is big that its shortcoming or deficiency are that (1) backs out difficulty; (2) operation case accident midway easily takes place; (3) need tubing string to provide than high pulling torque and axial tension, but in electric pump well, the following tubing string of electric pump is hampered or during the sand card, and transfer torque and pulling force downwards again cause the on-off connector can not uncoupling, directly influence the underground work process.Need tubing string to provide than high pulling torque and axial tension.
Three, summary of the invention:
The purpose of this utility model provides a kind of improved hydraulic pressure on-off connector, it can be avoided effectively and overcome shortcoming or the deficiency that exists in the prior art, lock dog mechanism avoids operation case accident midway, also need not tubing string any moment of torsion and pulling force are provided, and just can make on-off connector safety uncoupling.
Hydraulic pressure on-off connector described in the utility model, comprise box cupling, tube connector, top connection, seal, turn, lock dog, shear pin, lock tube and lower contact, it is characterized in that described top connection one end is connected with tube connector, the other end and lower contact fix, connect stop collar outside its top, the bottom is installed on lock tube, is installed on lock dog between lock tube and the lower contact.
Wherein, described top connection is provided with the overcurrent duct which is provided with axially, radially is connected with outer wall.Described top connection and lower contact are fixed by lock dog.Described top connection and lock tube are fixed by shear pin.Described top connection is provided with the hole of installing lock dog.Described lower contact is provided with the groove of installing lock dog.
The utility model compared with prior art has following advantage:
1, adopt ground hydraulic control, need not tubing string any load is provided, realize safe uncoupling, uncoupling is reliable, the success rate height, and performance is not influenced by tubing string mechanism;
2, adopt the lock dog locking mechanism, operation case accident midway easily takes place;
3, by regulating ground pressure, hydraulic line can use with other down-hole hydraulic control instrument polyphones.
Four, description of drawings:
Accompanying drawing is the utility model structural representation.
Five, the specific embodiment:
Referring to accompanying drawing, a kind of hydraulic pressure on-off connector comprises box cupling 12, tube connector 11, stop collar 10, top connection 9, seal 6,7,8, turn 5, lock dog 4, shear pin 3, lock tube 2 and lower contact 1.Top connection one end is connected with tube connector 11, and the other end and lower contact 1 fix, and connect stop collar 10 outside its top, and the bottom is installed on lock tube 2, is installed on lock dog 4 between lock tube and the lower contact.
The overcurrent duct 13 that top connection 9 is provided with axially, radially is connected with outer wall.Top connection 9 is fixed by lock dog 4 with lower contact 1.Top connection 9 is fixed by shear pin 3 with lock tube 2.Lower contact 1 is provided with the groove of installing lock dog.Top connection 9 is provided with the hole of installing lock dog, and lock dog 4 is installed in above-mentioned hole and groove.
