Abstract
The utility model relates to a kind of circlip type tiny junk fishing collar.Circlip type tiny junk fishing collar comprises top connection (1), and described top connection (1) lower thread connects simplified (2); Cylindrical shell (2) lower thread connects guide shoe (4); The end face of guide shoe (4) circumferentially on be evenly distributed with moving tooth (7), moving tooth (7) tilts along a direction, spacing ring (3) is provided with in cylindrical shell (2) bottom, spacing ring (3) carries out spacing by the shoulder of cylindrical shell (2) inwall to it, spacing ring (3) outer wall is circumferentially gone up and is fixed with spring leaf (5) by screw (6), spring leaf (5) is uniformly distributed, and spring leaf (5) inwardly tightens up gradually.Use this instrument fishing success ratio and number of times far less than existing instrument, greatly reduce operating cost, decrease empty situation of running tubing string, reduce operating cost.
Description
Technical field
The utility model relates to the fishing tool, particularly a kind of circlip type tiny junk fishing collar that oilfield downhole operation salvages construction small falling object.
Background technology
At job execution oil well, particularly run into the disconnected de-situation of oil pipe and non-Timeliness coverage in inclined shaft process, when just easily having produced sucker rod, oil pumping rod centering device is scraped situation about falling in well.Instruments such as " overshots with slot ", " tackling all problems at once " of employing is in the past salvaged, and can not play good salvaging effect, extend the engineering time.
Summary of the invention
In order to solve the problem of the technology existed in background technology, and a kind of circlip type tiny junk fishing collar is provided, use this instrument fishing success ratio and number of times far less than existing instrument, greatly reduce operating cost, decrease empty situation of running tubing string, reduce operating cost.
The invention for solving the technical problem reaches by following technical scheme: this circlip type tiny junk fishing collar comprises top connection, described top connection lower thread connector drum; Cylindrical shell lower thread connects guide shoe; The end face of guide shoe circumferentially on be evenly distributed with moving tooth, moving tooth tilts along a direction, cylindrical shell is provided with spacing ring in bottom, spacing ring carries out spacing by the shoulder of cylinder inboard wall to it, spacing ring outer wall is circumferentially gone up and is fixed with spring leaf by screw, spring leaf is uniformly distributed, and spring leaf inwardly tightens up gradually.
The utility model can have following beneficial effect compared with above-mentioned background technology: this part circlip type tiny junk fishing collar, can salvage the smallclothes instrument of the centralizer dropped in well and so on.When fishing string is after desired depth, be delivered on the moving tooth of guide shoe by rotating tubing string by revolving force, moving tooth rotates can introduce inner barrel by centralizer and small falling object, and spring leaf can stop that centralizer and small falling object exit.Large because holding junk volumetric spaces in this instrument feature work tube length cylinder, use this instrument fishing success ratio and number of times far less than existing instrument, greatly reduce operating cost, decrease empty situation of running tubing string, reduce operating cost.Really achieve easy and simple to handle, safety, decrease the labour intensity of employee, decrease the job execution time, decrease operating cost to greatest extent, and operating cost.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is decomposing schematic representations of accompanying drawing 1.
In figure: 1, top connection; 2, cylindrical shell; 3, spacing ring; 4, guide shoe; 5, spring leaf; 6, hold-down screw; 7, moving tooth.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in accompanying drawing, this circlip type tiny junk fishing collar comprises top connection 1, described top connection 1 lower thread connector drum 2; Simplified 2 lower thread connect guide shoe 4; The end face of guide shoe 4 circumferentially on be evenly distributed with moving tooth 7, moving tooth 7 tilts along a direction, be conducive to guide shoe 4 is incorporated in guide shoe 4 by centralizer or small falling object in rotary course, be convenient to salvage, cylindrical shell 2 is provided with spacing ring 3 in bottom, and spacing ring 3 carries out spacing by the shoulder of cylindrical shell 2 inwall to it, and spacing ring 3 outer wall is circumferentially gone up and is fixed with spring leaf 5 by screw 6, spring leaf 5 is uniformly distributed, and spring leaf 5 inwardly tightens up the centralizer being conducive to salvaging gradually and can not deviate from simplified 2.
When salvaging small falling object in well, the top connection 1 of instrument is connected with tubing string with box part, under enter designated depth, transmission device is utilized to be rotated by overall tubing string after being hampered, top connection 1 drives cylindrical shell 2 and guide shoe 4, and the moving tooth 7 of guide shoe 4 bottom rotates centralizer and small falling object to be dialled and falls apart and introduce cylindrical shell 2 inside.Centralizer and small falling object are fixed in simplified 2 by the spring leaf 5 of cylindrical shell 2 inside, carry out this operation repeatedly, large because holding junk volumetric spaces in this instrument feature work tube length cylinder, just can a large amount of centralizer of disposable salvaging and small falling object, junk is stored in cylindrical shell 2 and can not comes off.Trip out fishing string after salvaging completes top connection 1 and cylindrical shell 2 are disassembled, just inner junk can be taken out, achieve can be recycled of instrument.
Claims (1)
1. a circlip type tiny junk fishing collar, comprises top connection (1), it is characterized in that: described top connection (1) lower thread connector drum (2); Cylindrical shell (2) lower thread connects guide shoe (4); The end face of guide shoe (4) circumferentially on be evenly distributed with moving tooth (7), moving tooth (7) tilts along a direction, spacing ring (3) is provided with in cylindrical shell (2) bottom, spacing ring (3) carries out spacing by the shoulder of cylindrical shell (2) inwall to it, spacing ring (3) outer wall is circumferentially gone up and is fixed with spring leaf (5) by screw (6), spring leaf (5) is uniformly distributed, and spring leaf (5) inwardly tightens up gradually.
