摘　　要：讨论了典型的二维井眼轨道设计问题,建立了二维井眼轨道设计的一般数学模型,并求得了其全部精确解.这种方法避免了在设计中进行试算,设计计算简单、精确、快速.该模型具有普遍适用性,可广泛用于二维定向井、水平井和多目标井的井眼轨道设计.Typical 2D well-path planning problems are discussed in this paper, The general mathematical models for 2D well-path planning are established, and all their exact solutions are found. The new method has no need for using trial and error procedure to arrive at a satisfactory well-path in planning, and the design calculation is simple, accurate and quick. The models are of universal significance for 2D well-path and can be widely used to plan directional wells, horizontal wells and multiple target wells.
