Description
Technical field
The invention belongs to the equipment of oil well repairing operation, be arranged on the working rig hook that well head hangs on oil pipe,
For clashing into tubing coupling, make the connection thread looseness of tubing coupling, a kind of impact unclamping tubing coupling screw thread
Device.
Background technology
The degree of depth of most of oil-water wells more than 2000m, in well under enter the oil pipe of length supporting with the degree of depth, the length of oil pipe
The oil pipe of degree generally 9.5m, 2000m is to be formed by connecting by the oil pipe tubing coupling of many root 9.5m length.Will be by when well workover
These oil pipes trip out one by one, to be dismantled by the connection screw thread of oil pipe bottom Yu tubing coupling and could realize one when playing flowline
The operation that root root oil pipe trips out.Oil pipe owing to having employs the connection screw thread of certain time, oil pipe and tubing coupling in well
There is corrosion problem, the connection screw thread of oil pipe and tubing coupling cannot be unclamped by the way of the instrument of common dismounting screw thread.At present
The way of this problem of Solve on site is to change powerful hydraulic screw-on machine, and this way wastes time and energy, and changes powerful
Hydraulic screw-on machine also can damage oil pipe, reduces the service life of oil pipe.Sometimes on-the-spot in order to time-consuming, reduce construction trouble,
Using the artificial way laterally hitting tubing coupling with sledgehammer to loosen and connect screw thread, this way labor intensity is big, belongs in violation of rules and regulations
Operation, is prone to accidents, and also can damage oil pipe simultaneously.
Summary of the invention
It is an object of the invention to design a kind of impacter unclamping tubing coupling screw thread, the problem overcoming above-mentioned existence,
Use mechanization to loosen the connection screw thread of oil pipe and tubing coupling, reduce difficulty of construction, it is to avoid violation operation, it is ensured that safety is executed
Work.
The object of the present invention is achieved like this: includes suspension hook, connecting cross beam, impact body, hanger bar, hydraulic means, company
Flange, tubing coupling, pipe elevator, oil pipe, tubing coupling is connected with tubing round thread, and pipe elevator blocks tubing coupling, oil pipe
Hung on well head by working rig, the edge, upper surface of connection dish be left and right symmetrically arranged two hydraulic means, two hydraulic pressure dresses
The piston upper end put is linked into an integrated entity by connecting cross beam, connecting cross beam lifts impact body, connection dish has through hole, impact body pair
Through hole described in standard, is symmetrically installed two hanger bar, two hanger bar and two hydraulic pressure before and after the edge, upper surface of connection dish
Device is evenly distributed on the edge, upper surface of connection dish, and impact body is between two hydraulic means and two hanger bar, and two
The upper end of individual hanger bar respectively connects a suspension hook, and two suspension hooks can be suspended on the hook of working rig, and two suspension hooks are suspended on
After on the hook of working rig, tubing coupling through hole described in from connection dish is through being under impact body, and impact body alignment is oily
Pipe box cupling.
The invention has the beneficial effects as follows: the piston of two hydraulic means supports impact body, impact body is directed at tubing coupling,
Impact body can be made to pump from the top of tubing coupling by operation hydraulic means to clash into tubing coupling, make oil pipe connect
Hoop produces loosening, such that it is able to dismantle connection screw thread with general tool with the connection screw thread of oil pipe.Therefore, instant invention overcomes now
There is problem present in technology, have employed mechanization and loosen the connection screw thread of oil pipe and tubing coupling, it is possible to reduce difficulty of construction,
Avoid violation operation, it is ensured that safe construction, it is to avoid accident occurs, and does not damage oil pipe, has significant economic benefit and society
Benefit.
Accompanying drawing explanation
Fig. 1 is the structure chart of the present invention.
Detailed description of the invention
1 pair of embodiments of the invention illustrates below in conjunction with the accompanying drawings.
As it is shown in figure 1, embodiments of the invention include suspension hook 1, connecting cross beam 2, impact body 3, hanger bar 4, hydraulic means
5, connection dish 6, tubing coupling 7, pipe elevator 8, oil pipe 9, tubing coupling 7 threadeds with oil pipe 9, and pipe elevator 8 blocks oil
Pipe box cupling 7, oil pipe 9 are hung on well head (tubing coupling 7 is seated on pipe elevator 8) by working rig, the limit, upper surface of connection dish 6
Edge be left and right symmetrically arranged two hydraulic means 5, the piston upper end of two hydraulic means 5 is linked into an integrated entity by connecting cross beam 2, even
Connect lifting impact body 3 on crossbeam 2, connection dish 6 has through hole, impact body 3 are directed at described through hole, the limit, upper surface of connection dish 6
Being symmetrically installed two hanger bar 4 before and after edge, two hanger bar 4 and two hydraulic means 5 are evenly distributed on the upper end of connection dish 6
On edge, face (hanger bar 4 and hydraulic means 5 are not necessarily on same circumference, it is simply that excentric far and near different), at impact body 3
Between two hydraulic means 5 and two hanger bar 4, the upper end of two hanger bar 4 respectively connects a suspension hook 1, and two suspension hooks 1 can
To be suspended on the hook of working rig, after two suspension hooks 1 are suspended on the hook of working rig, tubing coupling 7 is institute from connection dish 6
The through hole stated is through being under impact body 3, and impact body 3 is directed at tubing coupling 7.
In Fig. 1, two hanger bar 4 are overlapping, and visual hanger bar 4 is front overhang peg, and rear suspension rods is lived by forward mounting pole spacing,
Two hanger bar are in the outside of impact body 3.Two suspension hooks 1 are also overlapping, in order to adapt to the structure of working rig hook, need
Design two suspension hooks 1, if working rig hook improves from now on, can be only with a suspension hook.
Hydraulic means 5 is connected with hydraulic power source, hydraulic power source provide power, and hydraulic power source is controlled to make hydraulic means by operator
5 can move back and forth.Hydraulic means 5 can also be pneumatic.
