Abstract
The utility model relates to a pipe column for a blowout preventer in an oil field, in particular to a pressure testing pipe column for the blowout preventer. The pipe column adopts the technical scheme that the pipe column mainly comprises a hanging ring, a pipe column body, a flying prevention plate and pressure testing blind plate connecting threads; the hanging ring is arranged at the top part of the pipe column body; the projecting flying prevention plate is arranged at the bottom part of the pipe column body; and the pressure testing blind plate connecting threads are arranged under the flying prevention plate. The utility model has the advantages that a novel pressure testing pipe column with an improved structure can effectively prevent the pressure testing pipe column from flying off due to ineffectiveness of the pressure test blind plate connecting threads, and avoid pressure testing accidents of the blowout preventer.
Description
One, technical field:
The utility model relates to a kind of oil field blowout preventer tubing string, particularly a kind of preventer pressure testing tubing string.
Two, background technology:
At present in oil drilling, well head must be installed preventer, according to related standards, situation under must simulation well after the preventer maintenance is carried out pressure testing, when the pressure testing of preventer, need the pressure testing tubing string with the simulation downhole tool, pressure testing tubing string commonly used now forms with one section drilling rod and certain thickness steel plate welding production.In the process of pressure testing, the pressure that the pressure testing tubing string is born acts on the flashboard of preventer, and what increased flashboard helps envelope power, and this does not conform to the actual conditions of down-hole; Be to ftracture easily on the other hand, drilling rod is flown out, cause the accident with the pressure testing tubing string that one section drilling rod and certain thickness steel plate welding production form.
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 preventer pressure testing tubing string is provided, and the pressure testing tubing string flies out when effectively avoiding the PRESSURE TESTING BLIND FLANGE connecting thread to lose efficacy, and avoids the generation of preventer pressure testing accident.
Its technical scheme is: mainly by suspension ring, tubing string body, anti-ly fly plate and the PRESSURE TESTING BLIND FLANGE connecting thread is formed, the top of described tubing string body is provided with suspension ring, the bottom is provided with the outstanding anti-plate that flies, and prevents that flying plate has the PRESSURE TESTING BLIND FLANGE connecting thread.
By the PRESSURE TESTING BLIND FLANGE connecting thread PRESSURE TESTING BLIND FLANGE and pressure testing tubing string are coupled together, the anti-plate that flies mainly is that the pressure testing tubing string flies out when preventing the inefficacy of PRESSURE TESTING BLIND FLANGE connecting thread, prevent that flying plate stops by the flashboard of ram preventer or by annular preventer glue core, body is consistent with the size of the flashboard of preventer, and suspension ring play lifting pressure testing tubing string.
The beneficial effects of the utility model are: the pressure testing tubing string flew out when the novel pressure testing tubing string after the architecture advances can effectively avoid the PRESSURE TESTING BLIND FLANGE connecting thread to lose efficacy, and avoided the generation of preventer pressure testing accident.
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: mainly by suspension ring 1, tubing string body 2, anti-ly fly plate 3 and PRESSURE TESTING BLIND FLANGE connecting thread 4 is formed, the top of described tubing string body 2 is provided with suspension ring 1, the bottom is provided with the outstanding anti-plate 3 that flies, and prevents that flying plate 3 has PRESSURE TESTING BLIND FLANGE connecting thread 4.
By the PRESSURE TESTING BLIND FLANGE connecting thread PRESSURE TESTING BLIND FLANGE and pressure testing tubing string are coupled together, the anti-plate that flies mainly is that the pressure testing tubing string flies out when preventing the inefficacy of PRESSURE TESTING BLIND FLANGE connecting thread, prevent that flying plate stops by the flashboard of ram preventer or by annular preventer glue core, body is consistent with the size of the flashboard of preventer, and suspension ring play lifting pressure testing tubing string.
The beneficial effects of the utility model are: the novel pressure testing tubing string after the architecture advances can effectively avoid PRESSURE TESTING BLIND FLANGE to connect The pressure testing tubing string flies out during thread failure, avoids the generation of blowout preventer pressure-testing accident.
