Abstract: A method for evaluating a planned well trajectory for avoidance of collision with an existing wellbore includes constructing a bounding box about the planned well trajectory and a bounding box for a trajectory of at least one existing wellbore. If there is no intersection between the bounding boxes, the planned well trajectory is used for drilling a well.

Abstract translation: 用于评估用于避免与现有井筒碰撞的计划井轨迹的方法包括构建关于所述计划井轨迹的边界框和用于至少一个现有井眼的轨迹的边界框。 如果边界框之间没有交叉点，则使用计划的井轨迹来钻井。
