Abstract
The utility model discloses a compound cable fisher, including barrel 2 that top connection 1 and top connection 1 are connected, barrel 2 is provided with interior gullet 3, barrel 2 is provided with guide 7, and guide 7 front end is provided with and cuts blade 8, and this fisher simple structure can introduce the barrel smoothly with rope class junk, cuts rope class junk at any time, prevents the formation of "cable piston", practices thrift the operating cost, improves the efficiency that rope class junk was dragged for, and safe and reliable carries out rope class junk and salvages, obtains extensive application in the oil field.
Description
Technical field the utility model relates to a kind of well workover fishing tool of sleeve pipe inner rope class junk, especially a kind of composite cable fisher.
Background technology is present, in workover operation construction, the fishing tool commonly used of sleeve pipe inner rope, cable, steel wire class junk has interior hook, outer hook, inside and outside combination ditch, wall hook etc., every kind of instrument all has only single compliance, and it is very little once to drag for clean possibility, improper as tools selection, take place to salvage drilling tool probably and blocked, form in " cable piston ".Salvaging to comparatively complicated sleeve pipe inner rope class junk not only needs repeatedly to change instrument, also will be lowered to cutting class fishing tool, repeats to go into the well, and prolongs the fishing cycle, increases operating cost.
Summary of the invention a kind of composite cable fisher of the present utility model can be introduced cylindrical shell smoothly with rope class junk, and cutting rope class junk stops the formation of " cable piston " at any time, saves operating cost, improves rope class junk and drags for the efficient that obtains.
Composite cable fisher of the present utility model comprises top connection, the cylindrical shell that is connected with top connection, and cylindrical shell is provided with interior hook tooth, and cylindrical shell is provided with guide shoe, and the guide shoe front end is provided with cutting blade.
Appended drawings 1 is a structural representation of the present utility model, below in conjunction with accompanying drawing the utility model is described further.
The specific embodiment by accompanying drawing 1 as can be seen, this composite cable fisher comprises top connection 1, the cylindrical shell 2 that is connected with top connection 1, cylindrical shell 2 are provided with interior hook tooth 3, cylindrical shell 2 is not held and is provided with guide shoe 7, guide shoe 7 front ends are provided with cutting blade 8.In the present embodiment, cutting blade 8 is welded on guide shoe 7 front ends by carbide alloy, so cylindrical shell 2 possessed the structure and the performance of interior hook, has introducing and cutting function to rope class junk simultaneously.Cylindrical shell 2 inwalls are welded with interior hook tooth 3, and interior hook tooth 3 is round helical pattern on cylindrical shell 2 inwalls.Top connection 1 is provided with screw thread 2 and connects with shank 4, has movable outer hook tooth 5 on the shank 4, possesses the structure and the performance of outer hook, and in the present embodiment, the quantity of interior hook tooth 3 is 8.In rope class fishing junk operation process, lift motion by rotating the class junk introducing cylindrical shell 2 back shanks 4 do risings of to restrict, the class of will restricting junk further twines and lifts to cylindrical shell 2, when rope class junk is difficult for " giving up ", can stop the formation of " cable piston " again, can cut off rope class junk by rotation at any time again.
