Abstract
The invention relates to a pressure balanced static sealing pressure workover operation device. On the device comprising expansion tube jacket (1), lifting hydraulic cylinder (2), upper beam (3), lower beam (4), upper blowout preventer (5) and lower blowout preventer (6) a pressure balanced hydraulic cylinder (7) is set. One end of cylinder of the pressure balanced hydraulic cylinder (7) is connected with the tube cavity at the lower end of expansion tube jacket (1). It is y provided with low energy consumption, rapid loading and unloading pressure, static process and no discharge outside of liquid in well completely.
Description
Technical field
The present invention relates to the oil well repairing operation device, particularly the static seal band is pressed the workover treatment device.
Background technology
In oil well repairing operation, it is a kind ofly can play the device of lower tubular column and downhole tool at well head under oil well and well band press strip spare that band is pressed the workover treatment device.Can be divided into two types of movable sealing and static seals by the sealing means between its wellhead assembly and tubing string, the former exists seal easy to wear, the use cost height, and the high and big shortcoming of environment pollution of fault rate, the latter has solved the former above-mentioned defective effectively.But existing static seal band presses the workover treatment device in operation process, except that overcoming the tubing string self gravitation, also need overcome the pressure effect of well liquid in the stratum, has the high shortcoming of energy consumption.
Summary of the invention
The objective of the invention is: provide a kind of energy consumption low pressure equalization type static sealed pressurized well-repairing working device.
Technical solution of the present invention is: it be include flexible pipe box, lifting hydraulic cylinder, top rail, lower transverse beam, on preventer, the static seal band of preventer is pressed on the workover treatment device pressure balance hydraulic cylinder is set down, an end of the cylinder barrel of pressure balance hydraulic cylinder is connected with the lower end tube chamber of flexible pipe box by pipeline.
Technique effect of the present invention is: it except that having advantage of low energy consumption, also have add, release speed is fast and process is steady, the liquid outside advantage of discharging not fully in the well.
