针对井眼轨道设计的内容、形式以及设计方法的多样性问题，提出了井眼轨道设计的广义方程．该方程与井眼轨道的具体描述模型无关，适用于定向井和水平井的二维和三维剖面设计．待钻井眼设计采用“空间圆弧段－稳斜井段”模型；绕障井段设计是将障碍物抽象为铅直圆柱；对于三维漂移轨道设计，除考虑最大井斜角和第一稳斜段外，还要确定初始方位角．通过对待钻井眼设计、绕障定向井设计和方位漂移轨道设计的分析，验证了该方程的正确性和普遍适用性
Aiming at the content, form and design method of wellbore trajectory design, a generalized equation of wellbore trajectory design is proposed. This equation has nothing to do with the well-described model of wellbore orbit and is suitable for 2D and 3D profile design of directional wells and horizontal wells. The design of the borehole to be drilled is based on the model of “circular arc section-steady inclined section”; the design of the bypassing section is to abstract the obstacle into a vertical cylinder; for the three-dimensional drift trajectory design, Segment, but also to determine the initial azimuth. The correctness and general applicability of this equation are verified by the design of borehole design, the design of the bypass fault orientation well and the azimuth drift trajectory design
