Abstract
The utility model relates to a wall-contact sucker rod overshot with guide shoes, which is used for the operation in an oil field. The utility model is composed of a righting guide mechanism which is composed of mushroom-shaped front guide shoes, T-shaped back guide shoes, a pressing spring and pressing blocks, wherein the top of each front guide shoe is provided with a guide needle, the four front and back guide shoes form a barrel shape in an interstice mode, the pressing blocks respectively clamp the clamp edges of the front and the back guide shoes, and the pressing blocks are fixed on the outer external surface of a sleeve barrel by screws. The pressing spring is arranged in a groove which is arranged at a rod part, and the tops of the front and the back guide shoes are all in inward chamfers. The utility model can conveniently and accurately salvage broken (dropped) sucker rods and increase the salvage success rate, and the utility model has the advantages of simple structure and convenient use.
Description
The utility model relates to sucker rod fishing device in a kind of oil field operation, particularly salvages the fishing socket of disconnected (taking off) sucker rod.
The present sucker rod fishing tool that uses, complex structure, nothing are set upright guide, waste time and energy during salvaging, and success rate is low; And because manually-operated is improper, fragile fish makes the accident complexity.
The purpose of this utility model be to provide a kind of simple in structure, contain the adherent guide shoe formula sucker rod socket of setting upright guide, it can salvage disconnected (taking off) beam hanger easily and accurately, improve fishing success ratio effectively, overcome the existing in prior technology weak point.
Technical solution of the present utility model is: mainly by top connection, clamping bar mechanism, sleeve, set upright guide and form; The shrinkage pool inner surface of top connection upper end is provided with tubing thread, be provided with clamping bar mechanism in its lower end shrinkage pool, and the lower end of top connection links to each other with sleeve; Above-mentioned set upright guide by forward and backward guide shoe, draw pin and stage clip, briquetting is formed, preceding guide shoe is the mushroom-shaped of circular arc and rectangle composition, back guide shoe is the T shape that trapezoidal and rectangle is formed, and the bar of preceding guide shoe grows up longly in the bar of back guide shoe, and the arc top of preceding guide shoe is provided with the shaft-like pin that draws; Four forward and backward guide shoes that are symmetry, terminal alignment setting are in twos formed a tubular with gap, the bar portion appearance both sides of the edge of forward and backward guide shoe are equipped with edge, four briquettings block the edge of forward and backward guide shoe bar portion outer ledge respectively, and with screw briquetting are fixed on the sleeve outer surface; The bar portion inboard of forward and backward guide shoe is equipped with several grooves, and stage clip is loaded between the external surface that reaches sleeve in the groove; The trapezoidal edge at the curved edge at preceding guide shoe top and guide shoe top, back all is inside chamfering.During use, earlier the tubing thread of the utility model by top connection is connected with oil pipe.When the sucker rod that salvaging comes off, adopt the loose-leaf clamp mechanism, fishing socket enters in the sleeve pipe with oil pipe, because the effect of stage clip makes forward and backward guide shoe be close to internal surface of sleeve pipe, is lowered to the precalculated position, the sucker rod that comes off is set upright, is incorporated in the sleeve by drawing the guide of setting upright that pin, forward and backward guide shoe and stage clip, briquetting form, and enter clamping in the loose-leaf clamp mechanism, and upwards promote the utility model then, can salvage the sucker rod that comes off; When salvaging the sucker rod of fracture, adopt the slip-type clamp mechanism, fishing socket enters in the sleeve pipe with oil pipe, be lowered to the precalculated position, the sucker rod of fracture is set upright, is incorporated in the sleeve by setting upright guide, and enter clamping in the slip-type clamp mechanism, and upwards promote the utility model then, can salvage the sucker rod of fracture.
The utility model is set upright guide owing to having adopted, thereby can it can salvage disconnected (taking off) beam hanger easily and accurately, improves fishing success ratio effectively, and the utlity model has advantage simple in structure, easy to use.
