In sum, the outer hook that the utility model provides, by top connection and shank are set to tubular body, in one end of leading cone, cavity is set, the other end arranges flushing eye, make flushing liquor can pass the inner chamber of top connection, the inner chamber of shank and the cavity of leading cone rinse from the flushing eye of leading cone junk, coupler body is adopted to hook junk, the utility model removes by adopting flushing liquor the reservoir sand or sediment that are buried on junk, solve existing outer hook and cannot remove the reservoir sand or sediment of burying junk, therefore, the problem of the salvaging to the junk of being buried by reservoir sand or sediment cannot be realized, reach the effect can salvaging the junk of being buried by reservoir sand or sediment.
Because existing outer hook cannot remove the reservoir sand or sediment of burying junk, usually the reservoir sand of burying junk is not removed or sediment is salvaged by force to junk, the coupler body of outer hook is caused easily to disconnect, the shank of outer hook is easily out of shape, even may be accidents caused, the cost salvaging construction increases and there is security risk, and the outer hook adopting the utility model embodiment to provide can remove the reservoir sand or sediment of burying junk, the reliability of the connection of coupler body and shank is higher, the salvaging intensity of coupler body is higher, coupler body can be avoided to disconnect, the problem of shank distortion, avoid the generation of accident, the cost that construction salvaged by the outer hook that the utility model embodiment provides is lower, safety is higher.
The outer hook structure that the utility model embodiment provides is simple, and dependable performance, is specially adapted to salvage the rope class junk fallen in well.
Pallet can be changed according to the internal diameter of sleeve pipe, and the outer hook that the utility model embodiment is provided can use in different sleeve pipe, expands the scope of application of outer hook.While the reservoir sand or sediment of burying junk being rinsed by the flushing liquor rinsing eye, the effect of well-flushing can also be reached.
Below in conjunction with Fig. 2, the operating principle of the outer hook 10 that the utility model embodiment provides is briefly described.
See Fig. 2, when oil-gas field downhole operation (as, during well workover), if desired the rope class junk in junk well is salvaged, the top connection 110 of outer hook 10 is connected with one end of oil pipe, outer hook 10 is made to be connected to form fishing string with oil pipe, by oil pipe by outer hook 10 G.I.H to junk top 2 ~ 3m (rice), the other end of oil pipe is connected with flushing pump by pipeline, open flushing pump, flushing liquor enters the inner chamber of oil pipe along the pipeline of the other end connecting flushing pump and oil pipe, and successively through the inner chamber of oil pipe, the inner chamber P of top connection 110, the inner chamber Q of the shank 120 and cavity O of leading cone 140, from flushing eye a ejection, junk is rinsed, slowly lower drain line, the coupler body 130 of outer hook 10 is made to hook junk, the scattered position of junk is piled up by pallet 150, and limit on junk and move, on carry fishing string, coupler body 130 hooks junk, fishing junk is gone out well.
In sum, the outer hook that the utility model provides, by top connection and shank are set to tubular body, in one end of leading cone, cavity is set, the other end arranges flushing eye, make flushing liquor can pass the inner chamber of top connection, the inner chamber of shank and the cavity of leading cone rinse from the flushing eye of leading cone junk, coupler body is adopted to hook junk, the utility model removes by adopting flushing liquor the reservoir sand or sediment that are buried on junk, solve existing outer hook and cannot remove the reservoir sand or sediment of burying junk, therefore, the problem of the salvaging to the junk of being buried by reservoir sand or sediment cannot be realized, reach the effect can salvaging the junk of being buried by reservoir sand or sediment.
Because existing outer hook cannot remove the reservoir sand or sediment of burying junk, usually the reservoir sand of burying junk is not removed or sediment is salvaged by force to junk, the coupler body of outer hook is caused easily to disconnect, the shank of outer hook is easily out of shape, even may be accidents caused, the cost salvaging construction increases and there is security risk, and the outer hook adopting the utility model embodiment to provide can remove the reservoir sand or sediment of burying junk, the reliability of the connection of coupler body and shank is higher, the salvaging intensity of coupler body is higher, coupler body can be avoided to disconnect, the problem of shank distortion, avoid the generation of accident, the cost that construction salvaged by the outer hook that the utility model embodiment provides is lower, safety is higher.
The outer hook structure that the utility model embodiment provides is simple, and dependable performance, is specially adapted to salvage the rope class junk fallen in well.
Pallet can be changed according to the internal diameter of sleeve pipe, and the outer hook that the utility model embodiment is provided can use in different sleeve pipe, expands the scope of application of outer hook.While the reservoir sand or sediment of burying junk being rinsed by the flushing liquor rinsing eye, the effect of well-flushing can also be reached.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
