摘　　要：采用段铣套管开窗方式进行侧钻中半径水平井时，设计确定出合理的段铣套管长度及井眼轨迹，对于施工时有效控制井眼轨迹尤为重要。该文在理论和实践基础上，提出了段铣套管长度及井眼轨迹的设计方法，并给出相应的计算模式。When a window is to be opened using section milling during sidetracking medium-radius horizontal wells,determining rational casing milling length and hole trajectory is very important to effectively control hole trajectory.On the basis of theory and practice,casing milling length and hole trajectory design methods are proposed and corresponding computing model is given in this paper
