Problems solved by technology

[0002] In oil and gas drilling operations, when the drilling liquid column pressure is lower than the formation pressure, there will be dangers of well kicks and blowouts, and even out-of-control blowout accidents will occur in severe cases, which not only threatens the safety of operators and equipment, but also Destroy underground oil and gas resources, and also cause serious damage to the environment; BOP groups and choke manifolds are key equipment for well control. At present, wellhead BOP groups and choke Box control, this technology is very mature; however, when there is an emergency shut-in due to abnormal drilling conditions such as well kick and overflow, it is necessary to closely cooperate with the personnel at all positions on site, and shut down the well in sequence according to the relevant requirements, which will cause It takes a long time to shut do

Abstract

A wireless remote centralized ground blowout preventer and choke manifold control system and a wireless remote centralized ground blowout preventer and choke manifold control method belong to the technical field of petroleum and natural gas well control. A choke manifold hydraulic throttle control device, a centralized control box, a driller control station and a wireless remote control station are added to an existing energy accumulator device. Integration of a ground blowout preventer and a choke manifold on a hydraulic control and electric control system structure is realized through the choke manifold hydraulic throttle control device and the centralized control box. The driller control station and the wireless remote control station respectively provide a unified ground blowout preventer and choke manifold control operation interface, and implement wired remote centralized control and wireless remote centralized control on the ground blowout preventer and the choke manifold in a wired connection mode and in a wireless connection mode. The risk of man-made misoperation is reduced, remote control is realized, and the emergency handling ability of the system is improved. Real-time data acquisition display and record on key parameters of the ground blowout preventer and the choke manifold is realized. The structure layout of the control system is optimized, and the size is reduced.
