[0044] The following introduces a specific embodiment:

[0045] As Figure 1 shown in the schematic diagram of the drill string structure composition, the whole set of drill strings includes a drill pipe 1, a downhole hose pusher 2, a hose propulsion ground control instrument 3, and a drag reduction steering device 4.

[0046] The drill pipe 1 is a tubing with a diameter of 73 mm, and the single root length is 1 m to 1.5 m. The two ends are standard screw threads, which can be quickly connected according to the depth of the horizontal radial hole. The lower part is connected to the downhole hose pusher 2 through screw threads. It is used to lower the whole set of drill strings to the designed horizontal radial hole position, and the high-pressure hose for drilling passes through the middle.

[0047] The downhole hose pusher 2 is a steel shell cylinder with a diameter of 150 mm and a length of 1 m. The shell is composed of two semi-circular steel plates. The specific structure is as Figure 2 shown, including a standard thread joint 21, a high-pressure hose inlet pipe 22, a DC double-motor synchronous system 23, an underwater propulsion speed sensor 24, a variable shaft diameter U-shaped wheel propulsion system 25, a universal joint coupling 26, a synchronous mechanical load sharing system 27, and a high-pressure hose outlet pipe 28. The downhole hose pusher 2 is connected to the hose propulsion ground control instrument 3 through a waterproof cable. It is used to provide additional thrust to the high-pressure hose during drilling and increase the horizontal drilling length.

[0048] Further, the high-pressure hose inlet pipe 22 is a seamless steel pipe with a diameter of 40 mm, extending from the front end of the downhole hose thruster 2 to the DC double-motor synchronous system 23. The high-pressure hose inlet pipe 22 can guide the high-pressure hose with a nozzle from the drill pipe to the front end of the downhole hose thruster 2, and the high-pressure hose outlet pipe 28 can guide the high-pressure hose with a nozzle from the tail of the downhole hose thruster 2 to the connected drag reduction and steering device 4.

[0049] Further, the DC double-motor synchronous system 23 consists of two submersible motors.

[0050] Further, the underwater propulsion speed sensor 24 is connected to the counting wheel, and the propulsion distance and speed are indirectly calculated by recording the number of turns of the hose passing through the counting wheel.

[0051] Further, the variable shaft diameter U-shaped wheel propulsion system 25 is composed of a first main drive rubber wheel 251, a first driven drive rubber wheel 252, and a first worm and worm gear drive 253, which can adapt to the passage of high-pressure hoses or nozzles with diameters of 17 - 28 mm and achieve automatic clamping.

[0052] Further, the synchronous mechanical load sharing system 27 consists of 6 drive unit modules, which are fixed on the external steel shell at a certain axial distance. Each drive unit module includes a second main drive rubber wheel 271, a second driven drive rubber wheel 272, a second worm and worm gear drive 273, a first pressure regulating spring 274, and a second pressure regulating spring 275; springs are installed outside each rubber wheel, and the other ends of the springs support on the cylinder of the steel shell. During feeding, the 6 drive unit modules work synchronously.

[0053] Further, the universal joint coupling 26 connects each drive unit module of the synchronous mechanical load sharing system 27 in series.

[0054] The hose propulsion ground control instrument 3 is the ground control system of the downhole hose thruster 2, specifically a control box, which can operate independently or be used in connection with a computer. The built-in executable control software can adjust the feeding speed and pulling speed of the high-pressure hose, and can output the total feeding length, real-time torque, and speed.

[0055] The drag reduction and steering device 4 has a cylindrical appearance with a diameter of 150 mm, and is connected to the downhole hose thruster 2 through a standard thread at the top. Inside, there is an arc-shaped channel for realizing a 90° turn of the high-pressure nozzle from vertical to horizontal. Roller bearings are arranged on the inner side of the arc-shaped channel to reduce the frictional resistance between the high-pressure hose and the side wall of the channel.

[0056] The specific application process is as follows:

[0057] (1) Use a geological drill to drill a vertical hole with a diameter of 168 mm, and determine the depth and orientation of the horizontal drilling through a borehole TV.

[0058] (2) Connect the drill pipe 1, the down-hole hose thruster 2, and the drag reduction and steering device 4 in sequence.

[0059] (3) Place the hose with nozzle into the drill pipe 1, introduce it through the high-pressure hose inlet pipe 22 until it reaches the inlet of the down-hole hose thruster 2. Turn on the ground control instrument 3 for the hose thruster. The DC dual-motor synchronous system 23 starts. The main drive rubber wheel and the slave drive rubber wheel of the variable shaft diameter U-shaped wheel propulsion system 25 rotate, clamp the high-pressure hose, and push the high-pressure hose through each drive unit module of the synchronous mechanical load sharing system 27 in sequence until it reaches the high-pressure hose outlet pipe 28 and enters the drag reduction and steering device 4. Under the feeding of the down-hole hose thruster 2, the hose reaches the outlet of the drag reduction and steering device 4, and then turn off the switch of the ground control instrument 3 for the hose thruster.

[0060] (4) Start the high-pressure nozzle and begin horizontal hole drilling. Simultaneously turn on the down-hole hose thruster 2. The underwater propulsion speed sensor 24 measures the hose feeding speed in real time and feeds back and displays it on the ground control instrument 3 for the hose thruster. The hose feeding speed can be controlled through the ground control instrument 3 for the hose thruster.

[0061] (5) After the horizontal hole is drilled to the designed length, turn off the high-pressure nozzle. The down-hole hose thruster 2 propels in the reverse direction to pull out the hose from the drag reduction and steering device 4, realizing the recovery of the hose.
