BYJ18-21/35 oil and water well with pressure operation device belongs to the light hydraulic auxiliary type with pressure operation device, can work with regular XJ250 workover rig or wheel type workover rig. The device including power part and wellhead operation part, and the power part is skid structure. It is main including power system, hydraulic station and long distance control system.; Wellhead operation part consists of string sealing system, lifting hydraulic cylinder, clamping system, balance pressure relief system, work platform, connecting plate and the driller's control platform, and ladder, escaping slide, tubing ramps, level adjuster device and other ancillary components; Power part and wellhead operation part are designed separately easy to achieve installation and transportation .

1, The wellhead BOP combination can reach the requirements of with pressure operation, after take out all the tubing pipes in the well, can use blind ram to sealing the wellhead. 2, Equipped with triplex ram BOP, when the pressure in the well rising or the with pressure operation device need to repair, can use half sealing ram of triplex ram BOP closed the annular space between casing and tubing; in the process of operation, the well's mouth out of control, can cut tubing to seal the well. 3, In the process of operation can with pressure on the downhole tools and force through tubing coupling; 4. In the situation of sealing the well, can through wellhead cross to do simple choke and blowout preventing, kill, flushing and other special operations.
