FIELD: oil and gas industry. ^ SUBSTANCE: single wells or wells forming clusters are drilled; production wells are equipped with wellhead equipment with X-tree including at least one side gate valve and one master gate valve, as well as underground cutout valve and throttle valve and monitoring and control members, which are installed on the loop, for example, fuse strip and gas line pressure monitoring valve. Operation of the well is performed at simultaneous control of production processes of hydrocarbons by means of the station. Control processes involve opening and closing of shutoff-control valves of well cluster by independent supply of working medium to actuators of shutoff-control valves, as well as flare and loop gate valves, which are arranged on pipelines in close proximity to control cabinet, for example on one common frame with control cabinet. Opening of shutoff-control valves of each well is performed in the following way: underground cutout valve, master gate valve, loop gate valve, side gate valve; closing is performed in the reverse order. ^ EFFECT: improving operating reliability of shutoff-control valves. ^ 3 cl, 5 dwg |
