Description
Technical field
The utility model relates to a kind of combined type top of fish finishing fisher, belongs to fish fisher technical field.
Background technology
Present stage, oil field first repaired fish often in well workover fishing, and then salvaged with fishing tool.So both time-consuming, effort and success rate were very low.This instrument that just need to develop a kind of new structure can disposablely complete finishing top of fish and salvage fish, thereby reduces cost, raises the efficiency.
Summary of the invention
The purpose of this utility model is the problem existing in order to solve above-mentioned prior art, and first repair fish often in well workover fishing in oil field present stage, and then salvages with fishing tool.So both time-consuming, effort and success rate were very low.And then provide a kind of combined type top of fish to repair fisher.
The purpose of this utility model is achieved through the following technical solutions:
A kind of combined type top of fish finishing fisher, comprise: mandrel, slips, release ring, leading cone, horn mouth and guide shoe, described bell-mouthed rear end is connected with the stage casing of mandrel, bell-mouthed front end is connected with guide shoe, the leading portion of the mandrel in horn mouth is provided with slips, discharges ring set on the mandrel of horn mouth internal slip front side, and the rear end of leading cone is threaded with the front end of mandrel, the front portion of release ring is provided with corrugated, corrugated the matching of afterbody of the corrugated and leading cone of described release ring.
Operating principle
According to steel theory of plastic deformation, utilize drilling tool deadweight and apply certain the pressure of the drill to force fish short-axis direction outwards to expand from internal diameter, long axis direction inwardly shrinks and top of fish is recovered or substantially return to former tubing string shape.In when work, leading cone rushes swollen internal diameter, and horn mouth contacts fish external diameter simultaneously and produces inside power, along with the increase top of fish that rushes swollen number of times produces plastic strain again, makes the tubing string shape that resiles, and then catches from fish inside, pulls fish out.While exiting instrument, to hit axle under drill string hammer, forward 2-3 circle, above carries drill string and can exit instrument.
The utlity model has following beneficial effect: the utility model is compared with fishing tool with single dressing tool, make finishing and salvage disposable completing, there is the remarkable advantage that operation is simple, the processing time is short, success rate is high.The utility model is simple in structure, and installation and removal are convenient, and cost of production and maintenance cost are all very low.The utility model is as long as removable parts part can adapt to the fish of plurality of specifications.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model combined type top of fish finishing fisher.
Reference numeral 1 in figure is that mandrel, 2 is that slips, 3 is that leading cone, 5 is that horn mouth, 6 is guide shoe for discharging ring, 4.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail: the present embodiment is implemented under taking technical solutions of the utility model as prerequisite, has provided detailed embodiment, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, a kind of combined type top of fish finishing fisher that the present embodiment is related, comprise: mandrel 1, slips 2, discharge ring 3, leading cone 4, horn mouth 5 and guide shoe 6, the rear end of described horn mouth 5 is connected with the stage casing of mandrel 1, the front end of horn mouth 5 is connected with guide shoe 6, the leading portion of the mandrel 1 in horn mouth 5 is provided with slips 2, discharging ring 3 is enclosed within on the mandrel 1 of horn mouth 5 internal slip 2 front sides, the rear end of leading cone 4 is threaded with the front end of mandrel 1, the front portion that discharges ring 3 is provided with corrugated 7, described release ring 3 corrugated 7 with corrugated the matching of afterbody of leading cone 4.
Described horn mouth 5 is threaded with the stage casing of mandrel 1.
Described horn mouth 5 is threaded with guide shoe 6.
It is 1.5～2mm with the end play that discharges ring 3 that described leading cone 4 tightens to its leading cone 4 of extreme position with mandrel 1.
The present embodiment has jointly formed finishing by mandrel, slips, release ring and leading cone and has salvaged the main part of fish, horn mouth and guide shoe have formed external shell, play the effect of introducing fish and auxiliary finishing fish, utilize steel theory of plastic deformation, in the situation that drilling tool is conducted oneself with dignity and applied certain the pressure of the drill, repeatedly repair the top of fish of fish, finally realized the salvaging of fish.
The above; it is only preferably detailed description of the invention of the utility model; these detailed description of the invention are all the different implementations based under the utility model general idea; and protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
