Embodiment Construction
[0036] The magnetic short section of the present invention will be described below with reference to the accompanying drawings and embodiments.
[0037] like figure 1 As shown, the hardware of the electromagnetic guidance system consists of the magnetic sub, the probe tube, the surface system and the drawworks. The magnetic sub and the drill bit are mounted together as the drill bit is run into the horizontal well. The magnetic sub is not only a part of the drill string, but also the signal source of the electromagnetic guidance system. During operation, the magnetic sub is usually installed on the drill collar closest to the drill bit. During the drilling process, the position of the magnetic sub can be approximated. that is the position of the drill bit. The probe pipe is lowered into a pre-drilled vertical well through a winch with a wire cable. The position of the probe pipe in the vertical well is that the axial center of the probe pipe is 1.5 meters above the intersecti...
