1results about How to "Large pressure adjustment range" patented technology

This invention belongs to the field of blowout preventer (BOP) control technology, and specifically relates to a BOP control system and method. A wellhead pressure monitoring module monitors the wellhead pressure in real time using a wellhead pressure sensor. A BOP control module monitors and adjusts the BOP pressure in real time. The controller outputs corresponding pressure control signals based on the real-time received wellhead and BOP pressures. A hydraulic power module provides low-pressure adjustment power to the BOP pressure via hydraulic pressure. A pneumatic power module provides high-pressure adjustment power to the BOP pressure via pneumatic pressure. Power is provided to the BOP through the hydraulic and pneumatic power modules. The hydraulic pump enables low-pressure adjustment, and the pneumatic pump enables high-pressure adjustment, thus expanding the pressure adjustment range of the BOP.
