Well contorl system are mainly consisted of BOP, control platform, manifold, valves and other related equipments. It is mainly used to shut the wellhead in oil testing, workover, well completion operations to prevent the blowout. It combined two fuctions of full shut and half shut,which enabled it easy to control and high pressure resistance.
It is used in oil well drilling to control the high pressure oil, gas and water, when the pressure of the well is too high, the BOP could shut off the well head. When inject the mud into the drill pipe, it has spool under the ram, which could replace the mud and increase the pressure of the hydraulic cylinder in the well, so it could control the blowout of the high pressure oil and gas.
