Abstract
The present invention relates to coiled tubing underground releasing tool used during underground work in petroleum gas oil producing operation field, belong to a kind of underground releasing tool.Including opening locking cap, opening sleeve.Opening locking cap and opening sleeve are attached separately on coiled tubing, then opening locking cap and opening sleeve are connected together；Make to meet card position to coiled tubing downhole tool under releasing tool by the deadweight of releasing tool, and continuing to be fed into coiled tubing makes releasing tool in place, then above carries coiled tubing, makes coiled tubing and meets card instrument between two parties, then unfreezing.The instrument is reliable and stable, can realize quick unfreezing in the case of coiled tubing meets card.
Description
Technical field
The present invention relates to underground operation tool, especially a kind of coiled tubing underground releasing tool in petroleum gas oil producing operation field.
Background technology
During continuous oil pipe operation, because technical measures are improper and the aspect reason such as tubing string, there is drilling tool by card accident.Traditional unfreezing mode be by coiled tubing repeatedly on put put unfreezing or use bumper jar unfreezing；Due to coiled tubing own characteristic, above put to put often also be not easy and stuck pipe post；Upper lifting power is excessive also to easily cause coiled tubing fracture.Bumper jar unfreezing is to, up or down with strong jarring force, loosening stuck point at stuck point, so as to reach the purpose of rapid unfreezing by bumper jar.But because bumper jar self seal material and machining accuracy influence, unfreezing effect is also undesirable sometimes, and more long the time required to unfreezing.
The content of the invention
The purpose of the present invention is directed to the problem of prior art presence, provides a kind of simple and reliable coiled tubing underground releasing tool.
To achieve these goals, the present invention takes following technical scheme：Coiled tubing underground releasing tool, including opening locking cap and opening sleeve, opening locking cap and opening sleeve in a tubular form and are axially arranged with opening, can be enclosed within coiled tubing.Opening locking cap one end and opening sleeve are connected through a screw thread, and the other end has certain taper.
The opening of opening locking cap and opening sleeve is mutually staggered certain angle, each one opening locking cap of connection in the two ends of opening sleeve, and opening locking cap and opening sleeve are the metal material with certain deadweight.Both openings are preferably mutually in 90-180 ° after opening locking cap and opening sleeve connection.
The advantage of the invention is that：Coiled tubing underground releasing tool simple structure, is made up of opening locking cap and opening sleeve two parts, and opening locking cap is tapered, is easy to releasing tool to transfer and proposes unfreezing in place and above.By opening locking cap and opening sleeve on coiled tubing, then opening locking cap and opening sleeve are connected together；Deadweight by releasing tool will meet card position under releasing tool to coiled tubing, and continue to be fed into coiled tubing and make releasing tool in place, then above carry coiled tubing, make chance card instrument unfreezing, both without worried to carry make coiled tubing be broken without worry machining accuracy problem cause solve card crash.Coiled tubing underground releasing tool is easy to operate simultaneously, and the unfreezing time is short.

Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings.
As Figure 1-Figure 5, the present invention provides a kind of coiled tubing underground releasing tool, including opening locking cap 1, opening sleeve 2, and opening locking cap 1 and opening sleeve 2 in a tubular form and are axially arranged with opening；Opening one end of locking cap 1 and opening sleeve 2 are connected through a screw thread, and the other end has certain taper.
Mutually stagger certain angle the opening of the opening locking cap 1 and opening sleeve 2.
The two ends of the opening sleeve 2 respectively connect an opening locking cap 1.
Both openings are mutually in 90-180 ° after the opening locking cap 1 and opening sleeve 2 are connected.
Coiled tubing downhole tool 5 meets card at downhole tool step 4 in Fig. 6, repeatedly on put that put cannot unfreezing；With reference to Fig. 7, opening locking cap 1 and opening sleeve 2 are first enclosed within coiled tubing 3 and connection screw thread is completed, opening is staggered in case being come off from coiled tubing 3.By the deadweight of releasing tool, under fall at tool stage for well rank 4, because opening locking cap 1 is tapered, releasing tool easily pass through downhole tool step 4；With reference to Fig. 8, coiled tubing 3 is continued to be fed into, make under the complete lower going-into-well of releasing tool after instrument step 4, above to carry coiled tubing 3, due to the effect of opening locking cap 1 and opening sleeve 2, made coiled tubing 3 and to meet card instrument 5 placed in the middle, reach unfreezing purpose.
