Abstract
The utility model relates to a sealing and suppressing device of a well sealing device for an oil field. The device comprises a pressure testing pump, a pressure meter, a high-pressure rubber pipe and a special joint, an oil pipe hanger, an oil pipe hanger plugging head, a well sealing device totally-sealed gate plate, a well sealing device semi-sealed gate plate, an oil pipe short connecting piece and the like, which are arranged on the mouth of a well. The special joint is in thread connection with the high-pressure rubber pipe by a sealing piece; the special joint is in the shape of a hollow pipe; the special joint is provided with an external thread; the oil pipe hanger plugging head is fixedly connected with the lower end of the oil pipe short connecting piece; the oil pipe short connecting piece is a tubular material; the upper end of the oil pipe hanger plugging head is in thread connection with the oil pipe short connecting piece; and the lower end of the oil pipe hanger plugging head is shaped like a circular cone with the external thread. The sealing and suppressing device of the well sealing device not only can simulate the practical working condition of the well sealing device to perform the sealing and suppressing test of the semi-sealed working condition and the totally-sealed working condition, but also can perform the sealing and suppressing test to each sealed part of the mouth of the well, thereby having the advantages of being small in volume, light in weight, simple in structure, convenient to use, low in manufacturing cost, reliable in work, low in failure rate, environment-friendly and the like.
Description
Technical field
The utility model relates to a kind of oil field and seals pressure device with blowout preventer.
Background technology
In the oil field operation process,, must all kinds of blowout preventers be installed at well head and provide safety guarantee well head prevention generation blowout for preventing blowout.Because well of every drilling well or well workover time all must do installation again blowout preventer, reinstall at every turn and finish, all must carry out bulge test to the sealing situation that blowout preventer and well head are installed.At present, in the oil field operation process, the seal and bulge test that blowout preventer and well head are installed all is to adopt special-purpose pump truck to the well site blowout preventer and well head to be carried out seal and bulge test.Because special-purpose pump truck involves great expense, quantity is few, can not each well workover team or drilling crew all be equipped with a cover, can only adopt which well workover team or drilling crew need carry out blowout preventer or well head seal and bulge test, make the plan again and call special-purpose pump truck by other department and carry out seal and bulge test to own operation team.This working condition required time is long, efficient is low, cost is high.The situation that the staff waits special-purpose pump truck for a long time often appears.
Summary of the invention
The purpose of this utility model provide a kind ofly have that volume is little, in light weight, simple in structure, easy to use, low cost of manufacture, reliable operation, fault rate be low, can seal pressure device with blowout preventer in antipollution oil field.
For achieving the above object, the utility model adopts following technical scheme:
A kind of oil field described in the utility model comprises hydraulic test pump, pressure meter, high-pressure rubber pipe with blowout preventer sealing pressure device and is installed in special joint on the well head, it is characterized in that: between described special joint and the high-pressure rubber pipe by seal with being threaded, special joint is a hollow tubular, have external screw thread on the special joint, other has the tubing hanger plug to be fixedly connected on the lower end of oil pipe short circuit, described oil pipe short circuit is a tube, the upper end of tubing hanger plug is connected with the oil pipe short circuit by screw thread, and the lower end of tubing hanger plug has externally threaded coniform.。
After adopting technique scheme, advantage of the present utility model is: described blowout preventer sealing pressure device can not only be simulated the seal and bulge test that the blowout preventer actual working state carries out half envelope operating mode and full envelope operating mode, can respectively seal the position to well head simultaneously and carry out seal and bulge test.This form of structure has can both be general with all size model blowout preventer with well workover and drilling well to the oil field, can accurately test the seal and bulge test of various blowout preventers and well head, and have that volume is little, in light weight, simple in structure, easy to use, low cost of manufacture, reliable operation, fault rate be low, advantage such as prevent the pollution of the environment.
Description of drawings
Fig. 1 is the user mode schematic diagram of an embodiment of the utility model.
Fig. 2 is the user mode schematic diagram of another embodiment of the utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of oil field described in the utility model seals pressure device with blowout preventer, comprises hydraulic test pump 1, pressure meter 2, high-pressure rubber pipe 3 and be installed in special joint 4, tubing hanger 5, tubing hanger plug 6, blowout preventer blind rams 7, blowout preventer on the well head partly sealing parts such as flashboard 8, oil pipe short circuit 9 and forming.Between described special joint 4 and the high-pressure rubber pipe 3 by seal with being threaded, special joint 4 is a hollow tubular, have external screw thread on the special joint 4, other has tubing hanger plug 6 to be fixedly connected on the lower end of oil pipe short circuit 9, described oil pipe short circuit 9 is a tube, the upper end of tubing hanger plug 6 is connected with oil pipe short circuit 9 by screw thread, and the lower end of tubing hanger plug 6 has externally threaded coniform.
Special joint 4 is installed in wellhead flange top wire hole position, between special joint 4 and the high-pressure rubber pipe 3 by seal with being threaded.
As shown in Figure 2, blowout preventer 10 is when sealing seal and bulge test entirely, seal by rubber seal and copper band between tubing hanger 5 and the wellhead flange, by the sealing of special oil pipe thread, seal by ring gasket between wellhead flange and the blowout preventer, after the blowout preventer inner chamber is filled it up with test(ing) medium between tubing hanger plug 6 and the tubing hanger 5, close blowout preventer blind rams 7, by the handle of continued operation hydraulic test pump 1, blowout preventer annular seal space internal pressure raises gradually, until arriving necessary requirement.
As shown in Figure 1, blowout preventer 10 is when carrying out half envelope seal and bulge test, seal by rubber seal and copper band between tubing hanger 5 and the wellhead flange, seal by the special oil pipe thread between tubing hanger plug 6 and the tubing hanger 5 and between oil pipe short circuit 9 and the tubing hanger plug 6, seal by ring gasket between wellhead flange and the blowout preventer, after the blowout preventer inner chamber is filled it up with test(ing) medium, close blowout preventer and partly seal flashboard 7, handle by continued operation hydraulic test pump 1, blowout preventer annular seal space internal pressure raises gradually, until arriving necessary requirement.Blowout preventer annular seal space pressure shows by pressure meter 2.
