  • Patent number: 11091976
    Abstract: A cable-type bridge plug setting and sealing tool, including a series of sequentially connected components provided in the following order: an upper connector, a driver, a control valve, a hydraulic actuator, and a piston adapter. When the control valve is in a first state, the driver sends, according to a first direction, a hydraulic fluid to the hydraulic actuator, thereby causing the hydraulic actuator to actuate a downward extension of the piston adapter. When the control valve is in a second state, the driver sends, according to a second direction, a hydraulic fluid to the hydraulic actuator, thereby causing the hydraulic actuator to actuate an upward retraction of the piston adapter. The cable-type bridge plug setting and sealing tool uses hydraulic control to achieve setting and sealing of a bridge plug, greatly reducing an operational risk coefficient and ensuring a degree of operational safety.
