| description | The invention discloses a liquid-driven coiled tubing jar, and relates to the technical field of drilling equipment. The jarring piston rod is compressed through liquid pressure, medium connection and disconnection of the cavity at the rear end of the jarring piston rod are achieved through the rotation control assembly, and therefore control over the pressure difference of the front end and the rear end of the jarring piston rod is achieved. The rotation control assembly is driven by liquid to rotate, and the rotation speed of the rotation control assembly can be adjusted by adjusting the flow speed of the liquid; therefore, the purpose of controlling the jarring frequency of the jarring piston rod is achieved. A movable drilling tool is not needed, fluid is used for driving jarring, the jarring frequency is high, the frequency can be adjusted, and meanwhile continuous jarring can be achieved.
