The invention discloses a bidirectional paired drilling method which includes the steps: inclined hole arrangement; drilling structure design; drilling device selection; inclined hole orientation drilling machine installation; trajectory control system control; drilling tool and well drilling process determination; mud system control; safety and well drilling accident preplanning; engineering management and economic technique analysis. Trajectory control system control serves as a key step and a core of a novel process, an orientation drilling method includes that a drilling hole meets a predetermined target according to design requirements by the aid of natural bending rules of the drilling hole and a manual angle building tool, the trajectory control system control includes that bendingmechanisms of the drilling hole are analyzed, modes and axes of drilling trajectories are designed, various inclination survey orientation instruments and measuring techniques are comprehensively utilized, drilling trajectories are controlled by the aid of various orientation drilling tool processes, so that a target trajectory is met. The method has the advantages of safety, high efficiency, lowcost and high operability.
