Well control blowout preventer locking shaft stroke position measuring system

Abstract

The invention aims to provide a well control blowout preventer locking shaft stroke position measuring system which comprises a driller station monitoring center host, well control blowout preventer slaves and a host ZigBee wireless sensor data transmission module, the well control blowout preventer slaves correspond to different positions, the host ZigBee wireless sensor data transmission module comprises a host transmitting module and a host receiving module, the host transmitting module is used for transmitting shut-in signals, the host receiving module is used for receiving locking shaft stroke position information, and each well control blowout preventer slave comprises a main controller, a slave ZigBee wireless sensor data transmission module and a locking shaft stroke position detection module, monitors locking shaft stroke positions in real time and returns data to the driller station monitoring center host. The well control blowout preventer locking shaft stroke positions can be automatically monitored, and the acquired data are transmitted to a computer display interface of a driller operation console in real time, so that well control management of a drilling well site is more intelligent and humanized.

Description

technical field [0001] The invention relates to the technical field of electronic information wireless transmission measurement, in particular to a system for measuring the stroke position of a locking shaft of a well control blowout preventer. Background technique [0002] Blowout is a phenomenon in which fluid in the formation is ejected from the ground or flows into other formations in the well, and it mostly occurs at the site of oil and gas exploitation. At present, when a blowout accident occurs in a drilling well site, only the on-site technicians can only rely on the manual opening of the valve, which is likely to cause lag and slowness in the shut-in action and affect the speed. In rainy, snowy, foggy or dark days, because the environment affects the line of sight, auxiliary tools such as a flashlight are needed at this time, but it is easy to cause misjudgment and it is impossible to determine whether the locking shaft travels reliably by viewing the travel positio...

Problems solved by technology

At present, when a blowout accident occurs in a drilling well site, only the on-site technicians can only rely on the manual opening of the valve, which will easily cause the lag and slowness of the shut-in action and affect the speed

In rainy, snowy, foggy or dark days, because the environment affects the line of sight, auxiliary tools such as a flashlight are needed at this time, but it is easy to cause misjudgment and it is impossible to determine whether the locking shaft travels reliably by viewing the travel position of the locking shaft through the observation window with the naked eye. to the designated area, resulting in incomplete shut-in, affecting the correct execution of the shut-in action, and completely relying on manpower to supervise the travel position of the locking shaft, which is likely to cause personnel fatigue, resulting in a slowdown in the shut-in speed or even failure

At present, there is no automatic control device at home and abroad to accurately measure the stroke position of the locking shaft of the well control blowout preventer
