Abstract
The utility model relates to a fisher used underground, which comprises a tubular box bell. External threads are arranged at two ends of the tubular box bell, and thread-making threads are arranged on the inner wall of the tubular box bell. A guide shoe is connected with the lower end of the tubular box bell through the external threads, and a stable balancing weight is arranged inside the guide shoe. The fisher used underground has the advantages of having compact and ingenious structure and practical functions, greatly improving success rate of thread making, reducing fishing cost and improving production efficiency.
Description
Technical field:
The utility model relates to a kind of fisher, particularly a kind of fisher that is used for field produces well trouble of lost tool in hole.
Background technology:
At present, in Petroleum Production, the foreign material of down-hole, oil field are salvaged the qualification because of environment and condition, and the salvaging process is difficulty relatively, existing fisher, centering process be difficulty relatively, and junk is not easy to enter female coupling tap, be easy to produce inclined to one side button, salvage failure, bring about great losses for the production in oil field thereby make.
Summary of the invention:
The purpose of this utility model is in order to overcome above deficiency, to provide a kind of success rate higher, the fisher that is used for the down-hole, oil field of easy centering.
The purpose of this utility model is achieved through the following technical solutions: a kind of fisher that is used for the down-hole, comprise the tubulose female coupling tap, be provided with external screw thread at tubulose female coupling tap two ends, on tubulose female coupling tap inwall, be provided with the thread making screw thread, be connected with guide shoe by external screw thread, in guide shoe, be provided with stable equilibrium's piece in tubulose female coupling tap lower end, when trouble of lost tool in hole is carried out in salvaging, fisher is put into, and junk imports making in mouthful screw thread of tubulose female coupling tap bottom by guide shoe, is centralized by the stable equilibrium again.
The utility model compared with prior art has the following advantages:
Its compact conformation, ingenious, the function practicality has improved the success rate of making mouth greatly, has reduced the salvaging cost, has improved production efficiency.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Number in the figure: 1-tubulose female coupling tap, 2-external screw thread, 3-thread making screw thread, 4-guide shoe, 5-stable equilibrium piece.
The specific embodiment:
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
Show a kind of embodiment that the utility model is used for the fisher of down-hole as Fig. 1, comprise tubulose female coupling tap 1, be provided with external screw thread 2 at tubulose female coupling tap 1 two ends, on tubulose female coupling tap 1 inwall, be provided with thread making screw thread 3, be connected with guide shoe 4 in tubulose female coupling tap 1 lower end by external screw thread 2, in guide shoe 4, be provided with stable equilibrium's piece 5.
When trouble of lost tool in hole is carried out in salvaging, fisher to be put into, junk imports making in mouthful screw thread 3 of tubulose female coupling tap 1 bottom by guide shoe 4, centralize by stable equilibrium's piece 5 again, thereby guaranteed the success rate of salvaging, reduced the salvaging cost, save the salvaging time, improved production efficiency.
