Description

technical field [0001] The invention relates to a ram blowout preventer used in the oil and gas development process. Background technique [0002] Petroleum resources are a non-renewable resource. In the process of oil and gas development, high-temperature and high-pressure wells, ultra-deep wells, wells containing acid and alkali, and wells containing hydrogen sulfide and other toxic gases continue to appear. sprayer. During the use of the existing blowout preventer, the sucker rod cannot be centered inside the blowout preventer, and when the sucker rod extends into and out of the blowout preventer, it will damage the internal ram of the blowout preventer, causing the blowout preventer to damage, thereby causing a blowout accident, while the existing blowout preventer is provided with a rated pressure, once the pressure in the well exceeds the rated pressure, it will be very dangerous, and the blowout preventer is prone to explosion and has poor safety performance.

Problems solved by technology

During the use of the existing blowout preventer, the sucker rod cannot be centered inside the blowout preventer, and when the sucker rod extends into and out of the blowout preventer, it will damage the internal ram of the blowout preventer, causing the blowout preventer to damage, thus causing blowout accidents. At the same time, the existing blowout preventers are equipped with rated pressure. Once the pressure in the well exceeds the rated pressure, it will be very dangerous. The blowout preventer is prone to explosion and has poor safety performance.
