Abstract
A directional drilling method applied to a rigid bending joint directional drilling device includes: obtaining geological data; determining a lateral drilling point and a target point of a branching borehole based on the geological data; drawing a target borehole trajectory of the branching borehole based on the lateral drilling point and the target point; obtaining parameters of the drill pipe; determining a propulsion force corresponding to the target borehole trajectory based on the parameters, the target borehole trajectory, and the geological data; and applying the propulsion force to the rigid bending joint directional drilling device for drilling the branching borehole. A directional drilling system and related devices are also disclosed.
