Patent number: 11946349Abstract: A downhole throttling device based on wireless control includes an inlet nozzle, a throttling assembly, an electrical sealing cylinder, a gas guide cylinder, a lower adapter sleeve, an end socket, a female sleeve, and electrical components. The inlet nozzle is connected to the throttling assembly, the throttling assembly is connected to the electrical sealing cylinder and the gas guide cylinder, the electrical sealing cylinder and the gas guide cylinder are both connected to the lower adapter sleeve, the lower adapter sleeve is respectively connected to the end socket and the female sleeve, and the electrical components are arranged in the electrical sealing cylinder. A throttling effect is achieved by detecting the temperature and pressure in a tube by a temperature/pressure sensor in the electrical components and controlling a motor to rotate a movable valve in the throttling assembly by a circuit control assembly, thereby achieving wireless control over downhole throttling.Type: GrantFiled: September 15, 2020Date of Patent: April 2, 2024Assignees: PetroChina Company Limited, Sichuan Shengnuo Oil. And Gas Engineering Technology Service Co., LtdInventors: Jun Xie, Huiyun Ma, Jian Yang, Chenggang Yu, Yukun Fu, Qiang Yin, Kui Li, Yuan Jiang, Dezheng Yi, Yanyan Liu, Haifeng Zhong, Xiaodong Liu
