Abstract
The utility model relates to a fishing tool for well drilling in an oil field, in particular to a novel die tap fisher. The novel die tap fisher adopts the technical scheme that the novel die tap fisher comprises a connector, a die tap, a short joint and a milling shoe or a guide shoe; one end of the connector is connected with the short joint in a movable manner and with the milling shoe or the guide shoe through the short joint; the die tap is arranged in the short joint; a guide body is arranged at the tail end of the short joint; and the maximal internal diameter of the guide body is larger than the external diameter of objects to be finished. The utility model has the benefits that when underground fishes are fished, the die tap can enter into water eyes of the fishes to be fished more easily under the guiding and the righting effects of the guide body, so as to improve the fishing effect and the finishing success ratio while fishing with the die tap, save a plenty of precious time for dealing with accidents, and improve economic benefit of well drilling.
Description
One, technical field:
The utility model relates to a kind of oil drilling fishing tool, particularly a kind of novel die nipple fisher.
Two, background technology:
Drilling tool or other tubing string well accident that ruptures takes place in oil drilling production at present often, accident often needs fish is salvaged after taking place, die nipple is a kind of fishing tool commonly used, die nipple drags in the process of fish going into the well, because condition effect such as size, the borehole wall of well are irregular, hole deviation, die nipple is difficult to enter the hydrophthalmia of fish, the one, delayed a large amount of valuable accident processing times, the 2nd, may make to salvage and lose efficacy, waste brill one time, really do not given play to the salvaging effect of die nipple.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of novel die nipple fisher of salvaging effect that improves is provided.
Its technical scheme is: be made of joint, die nipple, pipe nipple and milling shoe or guide shoe, one end of joint flexibly connects pipe nipple, connect milling shoe or guide shoe by pipe nipple, be provided with die nipple in the described pipe nipple, be provided with guide body in the end of described pipe nipple, the maximum inner diameter of guide body is bigger than the external diameter of object to be salvaged.
Above-mentioned guide body maximum inner diameter than the big 10mm of external diameter of object to be salvaged.
One end of above-mentioned joint is by the pipe nipple that is threaded, by the die nipple that is threaded.
The beneficial effects of the utility model are: when salvaging the down-hole fish, guiding and centralizing function by guide body, die nipple is than the hydrophthalmia that is easier to enter fish to be salvaged, salvaging effect and the fishing success ratio of die nipple salvaging fish have been improved, save a large amount of valuable accident processing times, improved the economic benefit of drilling well.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Five, the specific embodiment:
In conjunction with the accompanying drawings 1, the utility model will be further described:
Its technical scheme is: be made of joint 1, die nipple 2, pipe nipple 3 and milling shoe or guide shoe 4, one end of joint 1 connects pipe nipple 3 by screw thread 5, connect die nipple 2 by screw thread 6, connect milling shoe or guide shoe 4 by pipe nipple, be provided with die nipple 2 in the described pipe nipple 3, be provided with guide body 7 in the end of described pipe nipple 3, the maximum inner diameter of guide body 7 is than the big 10mm of external diameter of object to be salvaged.
The effect of guide body is that guiding is just relative with the hydrophthalmia of setting upright fish and die nipple, and the success rate of assurance salvaging can install extension nipple additional according to the salvaging length of fish; Die nipple works to salvage fish; Joint can be connected with drilling tool or other tubing string.
