用跟踪法求解单个弯曲钻孔中岩层的产状——通用地质坐标系应用实例(之五)

Following the Tracks of Attitude in a Curved Drilling -- Applying of General Geological Coordinate System (5)

根据通用地质坐标系的理论和方法,提出了求地下岩层产状的“最短捷径跟踪法”(简称跟踪法),解决了在单个弯曲钻孔中用“小圆交点法”求解岩层产状时,由于测量误差或岩层产状的微小变化而产生的小圆不相交的问题。跟踪法的计算结果还能平滑偶然偏差,从而更好地揭示出地下岩层产状的变化规律。

The attitude of blind rocks can not be calculated in terms of point of intersection of small circles in steregraphic projection net when small circles don’t intersect. This paper proposes following the tracks of attitude of blind rocks in sortest - range on the basis of theory and method of General Geological Coordinate System.
