摘要
井眼轨迹设计是定向井能否成功的关键技术之一，文中推导出的两维定向井轨迹设计通用方程，只是针对不同的轨迹类型定义方程的参数，就可以进行多种类型定向井的轨迹设计，简化设计过程。文中分析了三段制、五段制和双增轨迹在设计方面的差异与共同处，对推导出来的通用方程在实际应用中进行设计计算论证。
The development of general equation has simplified ZD directional well trajectory design. The basicrelationship can be modified easily for the various types of directional and horizontal well design. The variablesused in the equation are defined according to the particular geometry of every kind of well bores. The paper analyses the differences and common points of various types of trajectory design. The actual application of this generalequation is explained by examples.
