Overview Of Bop

During oil drilling, it is installed on the wellhead casing head to control the blowout device of high-pressure oil, gas, and water. When the oil and gas pressure in the well is high, the blowout preventer can close the wellhead (shut down). When the heavy mud is pressed into the drill pipe, there is a four-way under the ram, which can replace the mud invaded by gas, increase the pressure of the liquid column in the well, and suppress the ejection of high-pressure oil and gas.

Its types are divided into ordinary blowout preventer, blowout preventer and rotary blowout preventer. The blowout preventer can be activated in emergency situations to deal with any size of drilling tools and empty wells; the rotating blowout preventer can realize the blowout and drilling operation. In deep well drilling, in addition to two ordinary blowout preventers, blowout preventers and rotary blowout preventers are often added to make three or four combinations installed at the wellhead.

Annular Blow-out Preventer Annular Blow-out Preventer is usually equipped with a large gate with a ram-type blowout preventer, which forms a sealed annular space between the pipe string and the wellbore during operation. It can also be used independently when there is a pipe string in the well. The well is closed, but it will not work after a few times of use, and long-term shut-in use is not allowed.
