Abstract
The utility model relates to a well repair operation device, in particular to a novel well repair seal device for an oil field. The technical scheme includes that the novel well repair seal device for the oil field comprises a double ram type preventer, a seal steel ring, a four-way pipe, a oil pipe hanger, a oil pipe pressure tester, a casing pipe, an oil pipe, a bolt and a plug valve. The oil pipe is fixed in the inner portion of the casing pipe, the oil pipe pressure tester is arranged between the oil pipe and the casing pipe, the upper portion of the oil pipe is connected with the oil pipe hanger, the oil pipe hanger is connected with the four-way pipe, the four-way pipe is connected with the double ram type preventer through the bolt, the seal steel ring is arranged between the four-way pipe and the double ram type preventer, and the plug valve is arranged on the top portion of the double ram type preventer. The novel well repair seal device for the oil field has the advantages of finishing totally sealing the well when abnormal conditions appear in the process of repairing the oil well. The double ram type preventer and the plug valve which is arranged at the top of the double ram type preventer can achieve seal of a well opening and is free from throwing tubular columns into the oil well. The novel well repair seal device for the oil field has the advantages of avoiding economical loss and polluting the environment.
Description
Technical field
The utility model relates to a kind of workover operation device, particularly the novel well workover sealing device in a kind of oil field.
Background technology
Existing pumpingh well maintenance with full seal apparatus when the workover, tubing string plays a part very important, in the situation that oil well abnormal, the method that can only take to throw away tubing string in the oil well or rob the dress hanger, and the method for robbing the dress hanger approximately needs operation 20-30 minute, like this, has both caused the wasting of resources, miss again the best spray opportunity of robbing, caused huge pollution.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of oil field novel well workover sealing device, avoids economic loss, prevents contaminated environment.
Its technical scheme is: comprise double ram type preventer, ring gasket, cross, boll-weevil hanger, oil pipe pressure test device, sleeve pipe, oil pipe, bolt, plug valve, oil pipe is fixed on inside pipe casing, be provided with the oil pipe pressure test device between oil pipe and the sleeve pipe, the top connected pipes hanger of oil pipe, boll-weevil hanger connects cross, cross and double ram type preventer are bolted, and are provided with ring gasket between described cross and the double ram type preventer, and the top of double ram type preventer is provided with plug valve.
The beneficial effects of the utility model are: can be when workover abnormal situation, just can finish thorough shut-in well, the plug valve at double ram type preventer and top can effectively be realized wellhead sealing, and do not need tubing string is thrown away in the oil well, economic loss can be avoided, contaminated environment can be prevented again.
