The control device of the choke manifold is the hydraulic choke manifold control panel, capable of remotely adjusting the opening and closing states of the throttling device. It monitors and feeds back the internal pressure of the drill pipe, external casing pressure values, and positional parameters of the throttling components in real time. Through precise regulation of hydraulic flow, it achieves dynamic equilibrium in the downhole pressure system. This device integrates pressure monitoring and valve positioning functions, providing critical pressure management and control support for drilling operations.
This product employs an air-driven power system to acquire and present key operational metrics, including riser pressure, casing pressure, throttle valve position, mud pump stroke count, and operating frequency. Featuring a self-contained emergency hydraulic supply, the system supports modular functional expansion while delivering reliable performance, intuitive operation, and minimal maintenance requirements. The riser and casing pressure monitoring units utilize a fluid-based pressure sensing mechanism, distinguished by precision data acquisition, stable signal transmission, robust vibration resistance, factory-calibrated design, and intrinsic explosion protection. This technology applies aerospace-grade hydraulic system principles-specifically the vertical fluid retention methodology used in aviation hydraulic systems-to ensure continuous pressure monitoring accuracy. By integrating these mechanical principles, the system maintains data integrity under challenging operational scenarios, aligning with industrial standards for reliable downhole pressure management.
