Optical fiber is an excellent carrier of monitoring data information in the fracturing hole. Its entry into the hole while drilling can be achieved by winding it around the spiral groove of the fracturing pipe. However, since the front end of the fracturing pipe is connected to the fracturing tool and monitoring instruments, it is not suitable for rotating the fracturing pipe.

A circle of follower disc teeth on the axis side of the rear gear plate meshes with the drive gear of the drive motor after installation, and can be driven by the drive motor to drive the optical fiber axis frame as a whole to rotate forward and reverse around the axis. A circle of rear gear disc teeth on the outer diameter side of the rear gear plate can mesh with the cable arranging follower gear of the cable arranging positioner after assembly, driving the cable arranging follower gear of the cable arranging positioner to rotate forward and reverse.

[0031] The cable arrangement wheel frame 1-7 includes a wheel frame, an optical fiber positioning sleeve 1-13 that can be sleeved on the fracturing pipe, a cable arrangement positioner 1-5 arranged on the wheel frame, a tension monitor 1-3, and a follower gear plate 3-10 arranged on the inner ring of the wheel frame; the follower gear plate 3-10 is engaged with the transmission gear 2-15; the cable arrangement follower gear 3-7 of the cable arrangement positioner 1-5 is engaged with the rear gear plate teeth 2-3.

[0035] The clamping follower device 1-12 includes two left and right roller frames 2-19, two left and right clamping follower rollers 2-18 installed on the two roller frames 2-19, a tensioning spring buckle cap 2-21, a transmission belt 2-22, and a belt drive pulley 2-20.

[0036] The follower rollers are symmetrically installed on the left and right roller frames, and the clamping follower roller 2-18 is made of rubber with high toughness and large friction; after the clamping follower roller 2-18 clamps the fracturing pipe, the fracturing pipe moves forward or backward and drives it to rotate, and at the same time provides the drive motor 1-10 with a forward and reverse signal, that is, a reel-in signal; an axis hole 2-17 is provided on the roller frame 2-19 for installation on the seat shaft 2-9 of the roller seat 2-8 of the support frame 1-8, and the left and right roller frames 2-19 are strongly contracted by tightening the spring buckle cap 2-21 to clamp the fracturing pipe; the belt driving wheel 2-20 is installed on the roller frame 2-19 and is driven by the follower roller, and a transmission belt 2-22 is sleeved between the belt driving wheel 2-20 and the belt follower wheel 2-16, so that the rotation of the follower roller drives the transmission belt 2-22 to drive the belt follower wheel 2-16 and then the transmission gear 2-15 rotates.

[0037] The wiring wheel frame is the outermost frame, forming a wheel frame. The wiring wheel frame 1-7 also includes a front fiber guide pulley 1-4.

The fiber positioning sleeve 1-13 fits over the fracturing tubing and, together with the fiber guide pulley 1-4, guides the fiber into or out of the tubing's fiber slot 1-9. The tension monitor 1-3 monitors the tension of the fiber, which serves as a speed control signal for the drive motor 1-10. In the payout mode, tightening the tension accelerates the payout speed, while loosening it slows it down. In the take-up mode, tightening the tension slows the take-up speed, while loosening it accelerates it. The front follower gear, after installation, engages with the support frame's transmission gear, which drives the wiring wheel frame in forward and reverse rotation. In this embodiment, when the tension monitor detects a value close to the maximum tension that the optical fiber can withstand, the motor speed is slowed down. During payout, if the tension is high, indicating that more optical fiber is needed downhole, the motor speed needs to be increased to speed up the payout.

[0038] The cable locator 1-5 is arranged on the outside of the cable arrangement wheel frame 1-7, and includes a cable arrangement slide shaft 1-6, an optical fiber guide cylinder 3-6, a cable arrangement follower gear 3-7, a stabilizing slide bar 3-8, and a cable arranger 3-9. After installation, the cable arrangement follower gear 3-7 engages with the rear gear 2-3 of the optical fiber axis frame 1-11, and is driven by the relative rotation of the cable arrangement wheel frame 1-7 and the optical fiber axis frame 1-11. The cable arrangement follower gear 3-7 drives the cable arrangement slide shaft 1-6 to rotate, and drives the cable arranger 3-9 to move back and forth left and right on the stabilizing slide bar 3-8. The cable arranger 3-9 drives the optical fiber through the optical fiber guide cylinder 3-6 set to realize the regular arrangement and retraction of the optical fiber.
