Description
Technical field
It the utility model is related to the steel wire operation field of oil field development technical field, more particularly to oil/gas well, especially one
Kind jack catchs type steel-wire operation jar coupling, the pulling of downhole testing, injection well downhole flow regulator for producing oil/gas well, underground sliding bush switching, well
The various operations such as the salvaging of lower junk and the dispensing of underground throttle device, salvaging.
Background technology
When oil/gas well carries out underground work, steel wire operation is the operating type that one is easy to operate, construction cost is low, its
Can be with complete independently items underground work, such as fishing plugging device, prospect pit bed load face or to drag for shaft bottom sand sample, switching sliding sleeve, pulling inclined
The operations such as heart blanking plug, gas lift valve, chemical valve, pulling storm valve, pulling underground throttle device.When carrying out steel wire operation,
Downhole tool can be put into or pulled out the position specified by above carrying or transferring steel wire operation tool.
In daily steel wire underground work, by being limited by steel wire tensile load itself, when steel wire pulling force exceedes necessarily
Limiting value after, due to worry steel wire be pulled off, dare not continue above to propose operation, it is necessary to try repeatedly under side crops industry state
Draw, until instrument is pulled out.When tool card is in shaft bottom, when its unfreezing load is more than steel wire operation load, instrument can not just take out, by force
Even steel wire fracture is caused when being carried on row, it is necessary to carry out accident treatment.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of jack catchs type steel-wire operation jar coupling, can provide
Much larger than the jarring force of steel wire allowable load, the implementation tool unfreezing in the case where ensureing steel wire safety.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of jack catchs type steel wire operation shake
Hit device, including jar block, upper body, mandrel, transition joint, spring, catch jacket, middle pipe nipple and lower pipe nipple；Upper body is with
Between pipe nipple connected by transition joint, lower pipe nipple be connected with middle short-section thread, and in upper body, top is pierced by jar block
Upper body, and moving up, through the mandrel of transition joint, middle pipe nipple, lower pipe nipple to be threaded in jar block
Lower section, the spring being sleeved on mandrel are installed in middle pipe nipple, and the upper end of spring is spacing by transition joint, on lower end and catch jacket
End contact is spacing, and the claw on catch jacket is mutually chimeric with mandrel, in the interior groove of middle pipe nipple, can together with mandrel to
Upper movement and compress spring, after catch jacket and mandrel move up certain distance, claw and the mandrel of catch jacket lower part disengage, with
The jar block fast upward motion that mandrel is connected, realizes that jarring acts.
Between the jar block and upper body, between upper body and transition joint, between transition joint and middle pipe nipple, in
Between contact site between pipe nipple and lower pipe nipple, between lower pipe nipple and mandrel be both provided with " o " type sealing ring.
The beneficial effects of the utility model are：When carrying out downhole steel wire operation, when power tool, which above carries, to be hampered, start shake
Device is hit, realizes jarring releasing, the technology for causing downhole tool not take out due to steel wire pulling force deficiency when solving steel wire operation is difficult
Topic.
Brief description of the drawings
Fig. 1 is the structure diagram of the jack catchs type steel-wire operation jar coupling of the utility model.
In figure：1- jar blocks；2-o type sealing rings；3- upper bodies；4- mandrels；5- transition joints；6- springs；7- catch jackets；
Pipe nipple among 8-；Pipe nipple under 9-.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
As shown in Figure 1, the jack catchs type steel-wire operation jar coupling of the utility model, including jar block 1, upper body 3, mandrel 4,
Transition joint 5, spring 6, catch jacket 7, middle pipe nipple 8 and lower pipe nipple 9；Upper body 3 is connected with middle pipe nipple 8 by transition joint 5
Connect, lower pipe nipple 9 is threadedly coupled with middle pipe nipple 8, and jar block 1 is installed in upper body 3, and top is pierced by upper body 3, and can be upwards
It is mobile, through transition joint 5, middle pipe nipple 8, lower pipe nipple 9 mandrel 4 to be threaded in the lower section of jar block 1, be sleeved on core
Spring 6 on axis 4 is installed in middle pipe nipple 8, and the upper end of spring 6 is spacing by transition joint 5, lower end and 7 upper surface of catch jacket
Contact spacing, the claw on catch jacket 7 is mutually chimeric with mandrel 4, in the interior groove of middle pipe nipple 8, can together with mandrel 4 to
Upper movement and compress spring 6, after catch jacket 7 and mandrel 4 move up certain distance, the claw and mandrel 4 of 7 lower part of catch jacket are de-
Open, 1 fast upward motion of jar block being connected with mandrel 4, realize that jarring acts.
Between the jar block 1 and upper body 3, between upper body 3 and transition joint 5, transition joint 5 and middle pipe nipple 8
Between, the contact site between middle pipe nipple 8 and lower pipe nipple 9, between lower pipe nipple 9 and mandrel 4 be both provided with " o " type sealing ring 2.
The jarring that the jar block of the utility model completes bumper jar with upper body acts；Spring is the energy storage machine of bumper jar
Structure, can complete the accumulation of bumper jar energy；Catch jacket is the linkage mechanism of bumper jar, can aid in realizing the accumulation of energy with
Release.
When carrying out steel wire operation, bumper jar lower part connection operation instrument, top connection steel wire, puts into shaft bottom and carries out well
Lower operation.Above carry steel wire, when due to underground situation complexity causes power tool to be hampered when, continue above to carry, increase steel wire pulling force.With
The increase of steel wire pulling force, bumper jar mandrel moves up, and drives catch jacket to move up, and compresses spring.When steel wire pulling force reaches
During bumper jar operation setup load, at this time catch jacket lower part claw reach among at pipe nipple step groove, at this time on catch jacket with core
The claw that axis is mutually fitted together to is disengaged with mandrel, its restraining force to mandrel disappears, the jar block fast uplink being connected at this time with mandrel,
Hit body, to downhole tool one it is sizable on hit power, make instrument unfreezing.When a jarring is unable to unfreezing, steel is discharged
Silk pulling force, the mandrel downlink under weighted lever effect, with claw again chimeric, reset, it is possible to achieve jarring releasing repeatedly.
In conclusion the content of the utility model is not limited in the above embodiments, in same area it is insighted it
Scholar can easily propose other embodiments within the technological guidance's thought of the utility model, but this embodiment is all wrapped
Include within the scope of the utility model.
