BOREHOLE CONNECTION MODULE Russian patent published in 2020 - IPC E21B33/02 E21B34/16 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil and gas industry and can be used in development of devices for automatic control of technological processes of wells operation of hydrocarbon raw material deposits, mainly, gas or gas condensate ones. Disclosed is a module of tying a well, comprising a reinforcement unit and a control cabinet of a X-mas tree, connected to each other and installed on a common frame. Frame of reinforcement block is made in the form of spatial structure from profiled rolled stock, besides, on the frame there installed are gas pipelines, corrosion inhibitors and shutoff and control valves for the above well. At that, said reinforcement unit is located in protective ventilated cover, and housing of control cabinet of Christmas tree equipment is divided, preferably, into control compartment with operator panel and compartment of main hydraulic equipment. Inside the above cabinet there is a hydraulic system for control of the X-mas tree and the underground shutter valve of the said well, containing the KP and A devices, actuators, pilot distributors of low and high pressure with drive and cavities of inlet, outlet and drain, installed both along control line of root and side gate valves, and along control line of underground shutoff valve. Pressure accumulators are installed in hydraulic system and connected to hydraulic fluid tank, pumps, pressure regulators, multipliers and pipelines for supply of hydraulic fluid to actuators of side and ground root valves and underground cutoff valve. Hydraulic equipment of hydraulic fluid pressure control line in actuators of gate valves, underground cutoff valve, and hydraulic equipment of logical line of control cabinet, which contains mainly reduction valve, safety valve, locking needle valves of main lines and drainage, check valves are mounted on one hydraulic plate by means of butt and (or) cartridge-type assembly. At that, in the plate there are corresponding internal channels for supply, discharge of hydraulic fluid and drainage, as well as line for connection of instrumentation.

EFFECT: higher reliability of module operation as a whole and simplification of its design due to possibility to output information on condition of X-mas tree equipment and control cabinet to operator panel, control of X-mas tree in interactive mode and arrangement of equipment of valve unit in cover.
