摘　　要：针对分支井的三维轨迹特性,采用空间解析几何的方法建立了三维空间斜平面内水平井轨迹设计计算模型,根据推导出的轨迹设计模型编制了轨迹设计软件,该软件可以计算出轨迹设计的分段数据。经过测试,该轨迹设计软件计算出了预期的数据,这些结果为可视化三维轨迹设计提供了数据支持。同时该研究成果也可广泛应用于分支井、定向井、水平井、以及大位移井的设计计算。This paper has made the detailed theoretical analysis of 3-D horizontal well plan and tested well path plan software. Based on the characteristics of 3-D branch well path plan,this paper used the space geometry analytic method,and established a model in the 3-D space slanting plane for the horizontal well path plan and calculation,at the same time,the paper presented the program of multilateral well path plan.The program could calculate the segment data,to provide data to support the visualization of 3-D well path plan.Meanwhile,research results of this paper can also be widely used in design and calculations of branch wells,directional wells, horizontal wells,as well as the extended reach wells.
