Embodiment Construction
[0032] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0033] like figure 1 As shown, the present invention uses the theory and method of multi-body dynamics to establish an accurate mechanical model of the rotary steerable drilling system. Steering performance of the rotary steerable drilling system when drilling parameters, different drilling combinations, drill bit types and steering tool working parameters, so as to optimize the design of the lower drilling tool combination, predict and control the wellbore trajectory in real time. The steps are as follows:
[0034] 1) According to the structural information of the drilling system, the mechanical model of the structural unit is established, which mainly includes the following parts:
[0035] (1) Top drive unit 1: Coupling the motion equation of the motor into the mechanical model of the drilling system;
