3D sidetrack wells for bypassing obstacles for horizontal well in Luohe Oilfield,Ordos Basin

侧钻绕障井设计一般应包含:障碍物的形态描述;绕障井轨道的水平投影图设计;垂直剖面图设计;绕障井轨道计算。考虑井眼轨迹的空间形态和安全绕障距离沿井深变化等因素,本文对LH1-2-7P18井进行成功绕障,验证后顺利着陆。

The design for the sidetrack well for bypassing obstacles include:the illustration of obstacles;the horizontalprojection design of well trajectory for bypassing obstacle;vertical profile design;calculation of well trajectory for bypassing obstacle.This paper describes the successful practice in Well LH1-2-7P18 on the basis of spatial configuration of wellbore trajectory and safedistance of bypassing obstacle followed by well depth.
