[0034] The positioning sensing device includes: a drilling length sensor and an inertial sensor, which jointly determine the position of the drill tool 2.

[0035] The power mechanism includes: a main hydraulic station 10, a secondary hydraulic station 11, a compensator 12, a fuel tank 13, a mud pump, and a mud motor, wherein: the main hydraulic station 10, the secondary hydraulic station 11, the compensator 12, and the fuel tank 13 are all located on the carrier platform of the main frame 1, the mud pump is connected to the coiled tubing 5 to transport mud to the drill tool 2, and the mud motor is located between the drill tool 2 and the positioning sensing device.

[0036] The power mechanism is further provided with more than two underwater thrusters to assist the mud penetrator in positioning.

[0037] The umbilical cable is a double-layer torque spiral stainless steel wire, which includes, from the inside to the outside: a ground wire, a twisted pair, an optical fiber, a high-voltage cable, an inner sheath, an inner steel wire, an outer sheath, and an outer steel wire.

[0038] The described central monitoring unit includes: a central controller, a navigation controller, a signal acquisition module, an information transmission module, and an isolation module, where: the central controller, the navigation controller are connected to the information transmission module and transmit control information to the water surface monitoring power device; the signal acquisition module is respectively connected to the central controller, the navigation controller, and the positioning sensing device, converts the sensor information of the positioning sensing device into communication data and transmits it to the central controller and the navigation controller; the isolation module is arranged between the positioning sensing device and the signal acquisition module and disconnects the connection relationship between the two in the debugging state or the emergency state.
