由三钻孔确定岩层倾向的矢量计算法

The Vector Calculation of the Determination Stratum's Tilt Angle and Azimuth by Three Bore-holes

介绍一种以三个钻孔的测孔元素来确定岩层产状的方法。该方法是根据三个钻孔到某一岩层点的空间坐标，借助于空间矢量解析法来建立岩层的面方程，从而确定该岩层的倾角和倾向，并预计其它钻孔的深度。

he paper introduces a method with which the stratum's tilt angle and azimuth are determined by three bore-holes. According to the space coordinate of three bore-holes, the stratum's surface equation is established by means of space vector analysis, then the tilt angle and azimuth of the stratum around the bore-hole are calculated, and the depth of other bore-holes can be estimated.
