Abstract

Disclosed is a continuous conduit operation apparatus, which comprises a folding frame and a guiding and injecting integrated mechanism configured to pull the conduit to go downwards a well or upwards a lifting direction. The folding frame comprises a base, a mounting frame connected to the base in a movable connection, and a telescopic mechanism configured to rotate the mounting frame in a vertical plane around a position of the movable connection. One end of the telescopic mechanism is movably connected to the base, another end of the telescopic mechanism is movably connected to the mounting frame. The guiding and injecting integrated mechanism is arranged on the mounting frame. The present disclosure integrates the guiding function and the injection function to reduce the height of the apparatus and is suitable for operation environment with limited space and height.
