METHOD OF CONTROLLING SHUTOFF AND CONTROL VALVES OF WELL CLUSTER AND DEVICE THEREFOR Russian patent published in 2018 - IPC E21B34/16 E21B43/12 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the oil and gas industry and can be used for automatic control of technological processes. Method comprises opening and closing shut-off and control valves of a well cluster by independently supplying working fluid or electric current to the actuators of the shut-off and control valves and underground shutoff valves in a predetermined sequence. Method is carried out by means of a control system mounted in a cabinet, including instrumentation and controls, as well as a hydraulic system. Hydraulic system is designed to control the actuators of the shut-off and control valves with time delay and in a certain sequence. Cabinet is additionally fitted with equipment for controlling the electrical drives of the shut-off and control valve, which is installed on a Christmas tree, as well as pipelines in the immediate vicinity of the control cabinet on one common frame.

EFFECT: technical result is to simplify the process of managing the extraction of minerals, as well as to improve the reliability of wells in a hydrocarbon field.
