Description
Technical field
The utility model relates to the power tool that the well workover of a kind of oil field is used, particularly a kind of fisher of salvaging sucker rod in the pit shaft, and it and the supporting use of hydraulic tongs of oil field sucker rod can directly salvage out with falling into the interior sucker rod of pit shaft.
Background technology
Get in the oily process in well-digging in the oil field, and the sucker rod in the pit shaft often comes off in pit shaft, at present, the sucker rod that salvaging comes off in pit shaft mainly is to adopt three ball pumping rod salvagers, this fisher is made up of connecting rod and three parts such as ball, and its weight is heavier, during work, block sucker rod by ball, not only salvage inaccurately, and be easy to destroy the top " top of fish " of sucker rod when salvaging, meet when blocking in the fisher salvaging process, be difficult to fisher is pulled out, so the life-span is also shorter.
Summary of the invention
The purpose of this utility model is to want to overcome above-mentioned the deficiencies in the prior art, and a kind of new pumping rod salvager is provided, and this fisher is simple in structure, and is easy to operate, long service life.
For realizing that the technical scheme that above-mentioned purpose of the present utility model adopts is: a kind of pumping rod salvager, comprise connecting rod, the connecting rod top is provided with nipple, and its design feature is to be provided with two decks on connecting rod, all is provided with a card on the deck.
When the utility model used, connecting rod top sub and sucker rod joined, and by the bar that is rotationally connected, drove two decks and rotated, and make " shoulder " that drop on the interior sucker rod of pit shaft securely in deck, thereby sucker rod can not come off in lifting process.When the sucker rod in dropping on pit shaft " top of fish " is joint hoop or screw thread, it is lowered into " top of fish " following 1-2 rice, success can be salvaged by carrying sucker rod on the operation hydraulic tongs after just changeing connecting rod three circles with pipe wrench in ground; Sucker rod in dropping on pit shaft is lowered into it at " top of fish " following second or the 3rd sucker rod place during for the disconnected sucker rod that takes off, after three circles are just being changeed with pipe wrench in ground, on carry sucker rod and can salvage success; Sucker rod in dropping on pit shaft is crooked when irregular, and it is lowered into the following depth capacity of sucker rod " top of fish ", and ground is with the positive revolution circle of pipe wrench, and sensation is rotated strength when increasing, on carry sucker rod, can salvage success.
This shows no matter fall into sucker rod " top of fish " shape why in the pit shaft, adopt the utility model all can disposable salvaging success, it be simple to operate, directly is lowered into can carry out fishing after salvaging the position.Compared with prior art, it is simple in structure, weight saving more than four times, thereby survivable in the salvaging process " top of fish ", the salvaging process is simple, meets card and pulls out when motionless, directly pour out fisher and get final product, thus fisher be difficult for impaired, long service life.
