摘要
A method for drilling, comprising receiving, by a surface steerable system coupled to a drilling rig, BHA information from a rotary steerable bottom hole assembly (BHA) located in a borehole, calculating, by the surface steerable system, torsional and spatial forces acting on the rotary steerable BHA at a first location of the rotary steerable BHA with respect to a target drilling path responsive to the BHA information, calculating, by the surface steerable system, a first vector to create a convergence path from the first location of the rotary steerable BHA to the target drilling path that accounts for the torsional and the spatial forces acting on the rotary steerable BHA, causing, by the surface steerable system, at least one drilling parameter to be modified in order to alter a drilling direction of the rotary steerable BHA based on the calculated first vector, transmitting the at least one drilling parameter to the drilling rig to target the rotary steerable BHA in accordance with the first vector, and drilling the borehole using the rotary steerable BHA in response to the at least one drilling parameter.
