Problems solved by technology
[0002] In the process of oil extraction, due to the different methods of oil extraction, various oil extraction equipment are required. Among them, oil well pressurization is used to prevent oil production, and blowout prevention devices are required. Because most of the oil well blowout prevention devices require higher Strength is used to resist the high pressure in the oil well. Therefore, the structure and material strength requirements of the blowout device are relatively high. In the process of resisting the pressure, a certain amount of energy consumption is often required, and every time the oil production equipment is replaced, it will cause a lot of damage. inconvenience, so we need to innovate the existing technology

The invention discloses a self-pressure blowout preventer which comprises a housing, a fixing seat, a top cover, a working bin, air bags, air cylinders, oil inlet pipes, pressure relief pipes, oil plugs, pistons, sliding racks, a plug, a small air cylinder and a high-pressure air pipe; the fixing seat is arranged on the lower side of the housing; the top cover is arranged on the upper side of the housing; the working bin is arranged in the housing; the air bags are arranged on the left side and the right side of the working bin; the air cylinders are arranged on the lower sides of the air bags; the oil inlet pipes are arranged on the lower sides of the air cylinders; the pressure relief pipes are arranged on the oil inlet pipes; and the oil plugs are arranged on the pressure relief pipes. The self-pressure blowout preventer is provided with the air cylinders capable of switching pressure, pressure in an oil well pushes gas in the air cylinders, and the gas is supplied into the reversely fixed air cylinders, so that the effect of balancing pressure of the two sides of the self-pressure blowout preventer is achieved, the function of fixing an oil extraction device is achieved by inflating the air bags with the gas, and blowout caused by falling-off is avoided.
