Description
Technical field
The invention belongs to the equipment of oil well repairing operation, it is mounted on the working rig hook on well head suspension oil pipe,
For hitting tubing coupling, the connection screw thread of tubing coupling is set to loosen, specifically a kind of impact for unclamping tubing coupling screw thread
Device.
Background technology
The depth of most of oil-water wells is more than 2000m, in well tripping in and the mating length of depth oil pipe, the length of oil pipe
Degree is generally 9.5m, and the oil pipe of 2000m is formed by connecting with tubing coupling by the oil pipe of many 9.5m long.It will in well workover
These oil pipes rise out one by one, and dismantling the connection screw thread of oil pipe lower part and tubing coupling when playing flowline could realize one
Root root oil pipe acts the operation of going out.Since the oil pipe having has used certain time, the connection screw thread of oil pipe and tubing coupling in well
There are problems that corrosion, the connection screw thread of oil pipe and tubing coupling can not be unclamped with the method for the tool of common dismounting screw thread.At present
The method of this problem of Solve on site is to change powerful hydraulic screw-on machine, and this method is time-consuming and laborious, is changed powerful
Hydraulic screw-on machine can also damage oil pipe, reduce the service life of oil pipe.Sometimes scene reduces to construct bothering to save the time,
Connection screw thread is loosened using the method for manually laterally hitting tubing coupling with sledgehammer, this method labor intensity is big, belongs in violation of rules and regulations
Operation, is prone to accidents, while can also damage oil pipe.
Invention content
The purpose of the present invention is design it is a kind of unclamp tubing coupling screw thread impactor, overcome the problems, such as it is above-mentioned,
The connection screw thread of oil pipe and tubing coupling is loosened using mechanization, reduces difficulty of construction, avoids violation operation, ensures that safety is applied
Work.
The object of the present invention is achieved like this：Including suspension hook, connecting cross beam, impact body, hanger bar, hydraulic device, company
Disk, tubing coupling, pipe elevator, oil pipe are connect, tubing coupling is connect with tubing round thread, and pipe elevator blocks tubing coupling, oil pipe
It is hung on well head by working rig, the upper surface edge of terminal pad is left and right symmetrically arranged two hydraulic devices, two hydraulic pressure dresses
The piston upper end set is linked into an integrated entity by connecting cross beam, and impact body is lifted on connecting cross beam, there is through-hole, impact body pair in terminal pad
Through-hole described in standard, the front and back of the upper surface edge of terminal pad are symmetrically installed two hanger bars, two hanger bars and two hydraulic pressure
Device is evenly distributed on the upper surface edge of terminal pad, and impact body is between two hydraulic devices and two hanger bars, and two
Respectively one suspension hook of connection, two suspension hooks can be suspended on the hook of working rig for the upper end of a hanger bar, and two suspension hooks are suspended on
After on the hook of working rig, tubing coupling through-hole described from terminal pad passes through under impact body, impact body alignment oil
Pipe box cupling.
The beneficial effects of the invention are as follows：The piston of two hydraulic devices supports impact body, and impact body is directed at tubing coupling,
Impact body can be made to pump from the shock tubing coupling of the top of tubing coupling by operating hydraulic device, oil pipe is made to connect
The connection screw thread of hoop and oil pipe generates loosening, so as to dismantle connection screw thread with general tool.Therefore, the present invention overcomes existing
There is the problem of technology, uses the connection screw thread that mechanization loosens oil pipe and tubing coupling, it is possible to reduce difficulty of construction,
Violation operation is avoided, ensure that safe construction, accident is avoided, does not damage oil pipe, there is significant economic benefit and society
Benefit.
Description of the drawings
Fig. 1 is the structure chart of the present invention.
Specific implementation mode
1 pair of the embodiment of the present invention illustrates below in conjunction with the accompanying drawings.
As shown in Figure 1, the embodiment of the present invention includes suspension hook 1, connecting cross beam 2, impact body 3, hanger bar 4, hydraulic device
5, terminal pad 6, tubing coupling 7, pipe elevator 8, oil pipe 9, tubing coupling 7 are threadedly coupled with oil pipe 9, and pipe elevator 8 blocks oil
Pipe box cupling 7, oil pipe 9 are hung by working rig on well head（Tubing coupling 7 is seated on pipe elevator 8）, the upper surface side of terminal pad 6
Edge is left and right symmetrically arranged two hydraulic devices 5, and the piston upper end of two hydraulic devices 5 is linked into an integrated entity by connecting cross beam 2, even
Lifting impact body 3 on crossbeam 2 is connect, has through-hole, impact body 3 to be directed at the through-hole, the upper surface side of terminal pad 6 in terminal pad 6
The front and back of edge is symmetrically installed two hanger bars 4, and two hanger bars 4 and two hydraulic devices 5 are evenly distributed on the upper end of terminal pad 6
On the edge of face (hanger bar 4 and hydraulic device 5 are exactly not necessarily excentric far and near different on the same circumference), at impact body 3
Between two hydraulic devices 5 and two hanger bars 4, the upper end of two hanger bars 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, the institute from terminal pad 6 of tubing coupling 7
The through-hole stated passes through under impact body 3, and impact body 3 is directed at tubing coupling 7.
In Fig. 1, two hanger bars 4 are overlapped, and visual hanger bar 4 is front overhang hanging rod, and rear suspension rods are lived by forward mounting pole spacing,
Two hanger bars 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, are needed
Two suspension hooks 1 are designed, it, can be only with a suspension hook from now on if working rig hook improves.
Hydraulic device 5 is connect with hydraulic power source, provides power by hydraulic power source, hydraulic power source makes hydraulic device by operator's control
5 can move back and forth.Hydraulic device 5 can also be pneumatic.
