Fully intelligent drilling system is the future development direction of the directional drilling technology its underground system can intelligently identify the reservoir conditions. When the ground prediction error is large,fully intelligent drilling system can be used to automat-ically design the corresponding trajectory to complete the accurate construction target.Under the premise of obtaining the actual geological information,two-dimensional intelligent trajectory is de-signed for the existence of large area reservoir with depth error.In the process of drilling,the traj-ectory correction closed-loop control system is designed to effectively control the coincidence rate between the actual drilling wellbore trajectory and the designed wellbore trajectory.The proposed two-dimensional wellbore trajectory model can fully reflect the characteristics and requirements of intelligent drilling technology and can be widely used in the slant well,directional well,horizontal well trajectory design,and monitoring and correction design,making it more versatile.This new mathematical model and design method also laid the foundation for the promotion and application of intelligent drilling technology.
