Background
In the oil field drilling operation, a blowout accident happens occasionally, and the blowout is a phenomenon that formation fluids (oil, gas and water) continuously flow out without control and are sprayed out of the ground or invaded into other low-pressure layers. Emergency measures should be taken immediately after well blowout occurs to carry out blowout control, otherwise, in case of out of control, the loss of property such as damage of drilling equipment, scrapping of oil and gas wells and the like can be caused, and even casualties of personnel can be caused.
At present, the common treatment method of various domestic oil fields is to manually install check valves by petroleum workers, but the following problems exist in manual blowout control operation: firstly, a large amount of mud, oil gas and various harmful gases are generally sprayed during blowout, fire and explosion can be caused if the natural gas content is high during blowout, and if hydrogen sulfide in a blowout stratum of a sulfur-containing gas well diffuses into the air, great harm is caused to human bodies, and the operation environment is very severe and dangerous. Once the blowout tool fails, the fluid sprayed from the water hole has high pressure and high speed, so that field operators cannot approach the blowout tool. The check valve of the drilling tool is difficult to be buckled and screwed quickly, and the success rate of the on-site drilling tool check valve is seriously influenced.
