X-TREE CONTROL METHOD AND DEVICE FOR ITS IMPLEMENTATION

摘要

FIELD: oil and gas industry. ^ SUBSTANCE: control method of X-tree consists in opening/closing of shutoff-control valves by supplying the working medium to mechanisms of actuators of underground cutout valve, side and master gate valves by means of control station. Control station includes pneumatic hydraulic system connected through monitoring sensors of station operation parameters to control unit of the station. As control unit there used is software-and-hardware system with local control panel containing a display with sensor control to enter commands in on-line mode and local keyboard. ^ EFFECT: improved operating reliability of the control station and simpler design of the latter. ^ 18 cl, 3 dwg
