本文研究了存在邻井障碍物时定向井轨迹的设计方法。本方法充分利用防碰扫描程序,得到两维或三维轨迹设计的判断依据,不必建立复杂的数学模型,避免了繁琐的数值计算。做到优先采用两维设计,尽量避免复杂的三维设计,具有简便、易行的特点。这种方法也适用于存在其它类型障碍物时的定向井轨迹设计,对于现场实践具有一定的指导意义。 This paper studies the design method of directional well trajectory in the presence of adjacent obstacles. The method makes full use of the anti-collision scanning program to get the judgment basis of two-dimensional or three-dimensional trajectory design without having to set up a complicated mathematical model and avoids the cumbersome numerical calculation. Do priority to adopt two-dimensional design, try to avoid the complex three-dimensional design, with simple, easy features. This method is also applicable to the design of directional well trajectories in the presence of other types of obstacles, which is of guiding significance to field practice.
