摘　　要：讨论了一般二维井眼轨道设计问题.建立了二维轨道设计一般数学模型,根据轨道设计约束方程,可任意选择两个设计参数作为未知数进行求解,得到了全部解析计算公式.这种方法设计计算简单、精确、快速、灵活,具有普遍适用性.可广泛用于二维定向井、水平井和多目标井的设计,为井眼轨道设计提供了理论依据.General two-dimensional well-path planning problems are discussed in this paper. A general mathematical model for 2D well-path planning are established, and any two design parameters can be selected as unknowns to find their solutions based on the constraint equations of well-path planning, and all their analytical solutions are found. Using this method, the design calculation is simple, accurate and quick. It is of universal significance and can be widely used to plan 2D directional wells, horizontal wells and multiple target wells, and may provide theory foundations for well-path planning
