Blowout incidents occurred from time to time during China's modern industrial backwardness period, and each blowout touched the hearts of countless people. After all, this is a very dangerous situation. Now there are blowout preventers used to promptly close the wellhead, prevent blowouts, and make oil extraction projects increasingly safe
The structure of the anti spray device is very simple and the operation is more convenient. It is worth noting that the blowout preventer is fully sealed and semi sealed, providing better safety The types of blowout preventers include: conventional gate blowout preventer, manual single gate cable blowout preventer, manual fully sealed single gate blowout preventer, manual multifunctional single gate blowout preventer (fully sealed, semi sealed, self sealing), etc When heavy mud is pushed out of the drill pipe, there are four-way valves under the gate, which can replace the mud invaded by gas, increase the pressure of the liquid column in the well, and suppress the high-pressure oil and gas ejection In oil drilling, a blowout preventer is assembled on the wellhead casing head to control high-pressure oil, gas, and water. When the oil and gas pressure inside the well is high, the blowout preventer can shut off the wellhead. Blowout preventer is an indispensable tool in well control for underground operations, playing a crucial role in preventing and controlling blowouts
