Oil drilling, installed at thewellhead casing head, used to control the high pressure oil, gas, water blowout.Wells of oil and gas pressure is high, the BOP can be the wellhead closed(shut). The shutter has four, alternatively bullied invaded mud, increasing thepressure of the borehole fluid column, so as to suppress the high-pressure oiland gas discharged from the drill pipe is pressed into the heavy mud.
Itstype sub-ordinary blowout preventer, of universal blowout preventers androtating blowout preventer. Ordinary BOP ram with full-and semi-closure, fullclosure type blowout preventer can seal the entire wellhead; semi-sealed shutwellhead annular cross-section of drill pipe exists. Universal BOP can start incase of emergency to cope with any size drill and empty wells; the rotating BOPside spray edge drilling operations. In addition to the outside two ordinaryBOP, plus Universal BOP, rotating BOP, so three or four combinations installedat the wellhead deep drilling often. [1] annular BOP
