Abstract
The utility model discloses a kind of eccentric plugging fishing devices, it is made of connector on fishing socket, U-shaped card watt, mandril, spring and fishing head, connector is arranged on fishing socket on fishing head, U-shaped card watt, mandril and spring are separately positioned on fishing socket and fishing head in connector, U-shaped card watt is arranged on mandril, mandril is inserted in spring, and connector lower end has screw thread on fishing head；When use, connector on fishing head is arranged in head dipper lower end, then the utility model is transferred, after eccentric plugging fishing rod bending deformation, fishing socket can left-right rotation, can smoothly enter into curved fishing rod in fishing socket by the opening on fishing socket, U-shaped card watt is integral, guarantee that U-shaped card watt does not drop out, pulls eccentric plugging out under the action of U-shaped card watt；Present apparatus structure novel, it is easy to operate, it can shorten and salvage the time, improve working efficiency, reduce and salvage cost, avoid not coming out because of eccentric plugging fishing rod bending deformation, fishing, suitable oil field is widely popularized and applies.
Description
Technical field
The utility model relates to oilfield technology field, specially a kind of eccentric plugging fishing device.
Background technique
During injection well testing pulling, due to employee's misoperation or other reasons, eccentric plugging is caused to be salvaged
Situations such as rod bending deforms, after eccentric plugging fishing rod bending deformation, existing fishing head can not be pulled out, and work is increased
Difficulty and labor intensity increase maintenance maintenance expense, increase cost, the salvaging time is long, and working efficiency is low.
Utility model content
Utility model aims to solve in above-mentioned background technique, after eccentric plugging fishing rod bending deformation, show
There is fishing head that can not be pulled out, increase work difficulty and labor intensity, increases maintenance maintenance expense, increase cost,
The salvaging time is long, and ineffective problem provides a kind of eccentric plugging fishing device.
A kind of eccentric plugging fishing device, is made of fishing socket, U-shaped card watt, mandril, spring and connecting cylinder, connection
Cylinder is arranged on fishing socket, and U-shaped card watt, mandril and spring are separately positioned in fishing socket and connecting cylinder, and U-shaped card watt setting is being pushed up
On bar, mandril is inserted in spring, and connecting cylinder lower end has screw thread, and U-shaped card watt is overall structure；
There is opening on the fishing socket.
The working principle and use process of the utility model:
In use, being arranged connecting cylinder in head dipper lower end, the utility model is then transferred, eccentric plugging fishing rod is curved
After bent modification, fishing socket can left-right rotation, can smoothly enter into curved fishing rod in fishing socket by the opening on fishing socket, U
Type slips is integral, and is guaranteed that U-shaped card watt does not drop out, is pulled eccentric plugging out under the action of U-shaped card watt.
The beneficial effects of the utility model are:
The utility model structure novel, it is easy to operate, it is convenient and practical, it can shorten and salvage the time, improve working efficiency, drop
Low salvaging cost reliably effective, safety labor-saving can pull the curved eccentric plugging of fishing rod out, be avoided that because bias blocks
Device fishing rod bending deformation, fishing do not come out, and suitable oil field is widely popularized and applies.
Detailed description of the invention
Fig. 1 is the utility model overall structure diagram；
Fig. 2 is the decomposition texture schematic diagram of the utility model；
Specific embodiment
Please refer to shown in Fig. 1 and Fig. 2, a kind of eccentric plugging fishing device, be by fishing socket 1, U-shaped card watt 2, mandril 3,
Connector 5 forms on spring 4 and fishing head, and connector 5 is arranged on fishing socket 1 on fishing head, U-shaped card watt 2, mandril 3 and bullet
Spring 4 is separately positioned on fishing socket 1 and fishing head in connector 5, and U-shaped card watt 2 is arranged on mandril 3, and mandril 3 is inserted in spring 4
Interior, 5 lower end of connector has screw thread 51 on fishing head.
There is opening 11 on the fishing socket 1.
The working principle and process of the utility model:
It please refers to shown in Fig. 1 and Fig. 2, in use, being arranged connector 5 on fishing head in head dipper lower end, then transfers
The utility model, after eccentric plugging fishing rod bending deformation, fishing socket 1 can left-right rotation, pass through the opening 11 on fishing socket
It can smoothly enter into curved fishing rod in fishing socket 1, U-shaped card watt 2 is integral, and guarantees that U-shaped card watt 2 does not drop out, in U-shaped card
Eccentric plugging is pulled out under the action of watts 2.
