  • Patent number: 11732551
    Abstract: A fully electrically controlled intelligent subsurface safety valve is provided, including an upper joint, a lower joint, a magnetic switch, an upper electromagnetic suction module, a central flow pipe, a magnetic piston ring, a lower electromagnetic suction module, a rebound flap valve mechanism, a displacement sensor, a temperature and pressure sensor, a flow sensor, and a power communication composite cable connector. With the magnetic assisted reset of the two electromagnetic suction modules, the safety valve closes more quickly in emergency situations, improving the reliability of the safety valve. By using a magnetic excitation switch, the safety valve can be quickly opened and closed, and the open or close state can be maintained independently, saving energy consumption in the control system. The present disclosure can better meet the needs of onshore and offshore oil and gas production operations and gas storage operations.
