摘要
提出了存在邻井障碍时定向井轨道的优化设计方法。本方法充分利用防碰扫描程序进行判别选择，不必建立复杂的数学模型和进行繁琐的数值计算，优先采用两维设计，尽量避免复杂的三维设计，具有简便、易行的特点。在具体设计中也是充分利用防碰扫描程序使轨道达到优化。
The design method of directional well trajectory under existing drilled well obstacles is studied in this paper. The method takes good use of anticollision scanning programs to determine whether 3 dimensional planning is needed to avoid complicate mathematical model and boring numerical computing.According to this method ,2 dimensional planning is performed in advance and 3 dimensional is taken only when 2 dimensional planning failed . This method can also be used when the obstacles are not existing drilled wells .
