摘　　要：完全智能钻井系统是未来定向钻井技术的发展方向,其井下系统可以智能识别储层情况,在地面预测出现较大误差时,能够自动设计相应的井眼轨道完成精确中靶的施工目标。在能够获取实际地质信息的前提下,对于存在埋深误差的大面积储层,设计了二维智能井眼轨道。设计的轨道修正闭环控制系统,能有效控制井眼轨迹与设计轨道的符合率。提出的二维井眼轨道模型能够充分反映出智能钻井的技术特点和需求,并具有通用性,可广泛应用于斜直井、定向井、水平井的轨道设计、监测及修正设计,这种新的数学模型和设计方法为智能钻井技术的推广和应用奠定了基础。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.
