FIELD: oil and gas production. ^ SUBSTANCE: group of inventions refers to gas producing industry and can be implemented for automatic control over processes at gas producing well operation. The method includes control over Christmas tress of a well cluster and consists in opening and shutting off Christmas tress of a well cluster by means of independent supply of working agent into actuators of side and borehole gates, underground shut-off valves and valves regulating yield of each well. Also liquid is used as working agent. Operational pressure of liquid is preliminary created in pneumatic hydro-accumulators of pressure united with a tank of working agent, with pumps, pressure regulators and multipliers into a hydraulic system. To implement the method there is disclosed a station containing a control cabinet, wherein the hydraulic system for control over the Christmas tree and the underground shut-off valve of wells is assembled; the system contains instruments of control equipment and automation, actuators, and distributors with a drive and with cavities of inlet, outlet and drainage installed as in the line of control over borehole and side gates, so in the line of control over the underground shut-off valve. ^ EFFECT: increased reliability of operation by means of functioning of station regardless of source voltage; also simplification of requirements to operation. ^ 19 cl, 2 dwg |
