Abstract
The utility model discloses a coiled tubing fisher used for workover in the petroleum industry, which can successfully fish out a coiled tubing falling down in a well. The fisher comprises a cylinder, wherein the two ends of the cylinder are connected with an upper connector and a guide shoe; a fishing mechanism mounted in the cylinder comprises a slip sliding rail and a fishing slip, the fishing clip is mounted on the slip sliding rail, and an upper chock block and a lower chock block are fixed at the upper end and the lower end of the slip sliding rail respectively. During use, the tool and a drilling tool are connected and are put into the well, through the dialing guide of the guide shoe, a fish is led to enter the cylinder, and the fish can be fished by lifting the cylinder. According to the utility model, the problem about the fishing of a coiled tubing, with a bent fish top and serious deformation, in a deep well or a big hole is solved. The fisher is quite effective for fishing irregular small-diameter pipes and rods, with bent fish tops, deformation and other defects. Through the adoption of the fisher, the working efficiency is greatly improved under construction, and the operating cost of workover is reduced.
Description
Technical field
The utility model relates to petroleum industry well workover fishing tool, particularly well workover coiled tubing fisher, can successfully salvage the coiled tubing of well.
Background technology
Along with coiled tubing technology is in the extensive use in each oil field, bury the disconnected coiled tubing taking off in well of the reasons such as sand card, trouble of lost tool in hole or dirt card, viscous crude or high content of wax card, casing damage card due to sand, in major diameter sleeve pipe to its salvaging, when running into top of fish and being bending, conventional slip socket and female coupling tap cannot be salvaged it, bring very large difficulty to salvaging construction, therefore the on-the-spot a kind of instrument that can salvage irregular coiled tubing of development of being badly in need of.
Summary of the invention
The purpose of this utility model is to provide well workover coiled tubing fisher, can successfully salvage the coiled tubing of well, reduces the difficulty of salvaging construction, improves operating efficiency.
Technical solution of the present utility model is: well workover comprises cylindrical shell with coiled tubing fisher, the two ends of cylindrical shell connect top connection and guide shoe, the salvaging mechanism being arranged in cylindrical shell comprises slips slide rail and fishing slip, fishing slip is arranged on slips slide rail, fixes block and lower block at the two ends up and down of slips slide rail.When use, this instrument is connected to G.I.H with drilling tool, draws by dialling of guide shoe, thereby make fish enter cylindrical shell, above carry and can realize salvaging.
The utility model compared with prior art has following useful effect: the utility model has solved in deep-well, the bending of big hole top of fish, has been out of shape the salvaging problem of serious coiled tubing, and also very effective to the salvaging of the irregular minor diameter tubings such as top of fish bending, distortion, bar class, in construction, greatly improve operating efficiency, reduced workover treatment cost.Be embodied in:
1, in the utility model cylindrical shell, be provided with slips slide rail, salvaging scope is larger;
2, slip insert is row's shape tooth, and horizontal space is larger, can the larger coiled tubing of top of fish bending be salvaged;
3, the slips slide rail in this instrument cylindrical shell, belongs to side direction during to fishing junk and exerts pressure, so can salvage tubing, bar class junk without box cupling.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is upward view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing in detail the utility model is described in detail, referring to Fig. 1 and Fig. 2, well workover comprises cylindrical shell 2 with coiled tubing fisher, the two ends of cylindrical shell 2 connect top connection 1 and guide shoe 7, the salvaging mechanism being arranged in cylindrical shell 2 comprises slips slide rail 5 and fishing slip 4, fishing slip 4 is arranged on slips slide rail 5, fixes block 3 and lower block 6 at the two ends up and down of slips slide rail 5.The front end end face of slips slide rail 5 is lower inclined planes, is provided with swallowtail track, is bolted on the inwall of cylindrical shell 2, and fishing slip 4 can slide up and down on slips slide rail 5.Fishing slip 4 is the block bodies of rectangle, and rear end end face is that lower inclined plane is provided with dovetail groove and coordinates with slips slide rail 5, and slip insert is longitudinally arranged, arranges and be welded on front end end face, and slip insert is for arranging shape tooth, and horizontal space is larger, sees Fig. 2.Upper block 3 is bolted on the inwall of cylindrical shell 2, and its thickness is greater than the thickness of slips slide rail 5 upper ends.Lower block 6 is up-small and down-big inner conical pieces, is welded on the inwall of cylindrical shell 2, is positioned at the end, lower end of slips slide rail 5, is convenient in junk entering tool.The interior two cover salvaging mechanisms that arrange of cylindrical shell 2.After junk is salvaged, be held between two fishing slips 4, carry hold tighter on more.
concrete use as following:with time the coiled tubing salvaged as required external diameter select suitable fishing slip 4.When installation, by dismantling top connection 1, block 3 in taking-up, changes fishing slip 4.While salvaging construction, this instrument is connected G.I.H by top connection 1 with drilling tool, presses gently behind fish finding top, above carries 0.5m, rotates this instrument and introduces junk, above carries and can realize salvaging.
