DOWNHOLE THROTTLE DEVICE BASED ON WIRELESS CONTROL Russian patent published in 2022 - IPC E21B43/12 E21B34/06 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to equipment for the extraction of oil and natural gas with wireless control. Downhole choke device based on wireless control contains an inlet pipe, a choke assembly containing the upper, middle and lower adapter sleeves. The fixed and movable valves are connected by a shaft to an electric sealing cylinder containing a motor. The circuit control assembly includes a signal transceiver and a control IC, and a battery assembly. The gas pipeline cylinder is a housing that, together with an electric sealing cylinder located inside it, forms a channel for the flow of oil and gas. The end socket contains a temperature and pressure sensor, a female sleeve. The inlet branch pipe is connected to the throttle assembly, the electric sealing cylinder and the gas pipeline cylinder are connected to the lower adapter sleeve, the end socket is located in the female sleeve. The schema control node is configured to communicate the detected data to a control host, configured to send instructions to the schema control node. The control IC chip of the circuit control unit is configured to output the opening degree instruction to the motor using the built-in opening degree calculation control module.

EFFECT: providing the ability to control the degree of opening of the throttle branch pipe via wireless communication, increasing the efficiency and safety of the development of wells with natural gas.
