DOWNHOLE THROTTLING DEVICE BASED ON WIRELESS CONTROL

摘要

Disclosed is a downhole throttling device based on wireless control. The downhole throttling device comprises an air inlet nozzle (1), a throttling assembly (2), an electrical sealing cylinder (3), an air guide cylinder (4), a lower adaptor sleeve (5), an end socket (6), a female sleeve (7), and an electrical assembly (8), wherein the air inlet nozzle (1) is connected to the throttling assembly (2), the throttling assembly (2) is connected to the electrical sealing cylinder (3) and the air guide cylinder (4), the electrical sealing cylinder (3) and the air guide cylinder (4) are both connected to the lower adaptor sleeve (5), the lower adaptor sleeve (5) is respectively connected to the end socket (6) and the female sleeve (7), and the electrical assembly (8) is arranged in the electrical sealing cylinder (3). In the downhole throttling device, a temperature and pressure integrated sensor in the electrical assembly (8) is used for detecting the temperature and pressure in a pipe, and a circuit control assembly (802) controls an electric motor (801) to rotate a movable flap (204) in the throttling assembly (2) to achieve a throttling effect, thereby achieving wireless control over downhole throttling.
