定向井井身剖面计算新方法这里推导出一种计算井身剖面的新方法──割线法。该法认为相邻两测点井段为一条井斜和方位都在逐渐变化的空间圆弧,整个井段由若干曲率不等的圆弧组成。该法考虑了方位的变化,用井段在空间的实际形状进行计算。由图1 知全角ε即∠BCD可由...
A New Method for Calculating Directional Shaft Profile This section presents a new method for calculating the profile of a wellbore - the secant method. The law holds that the two adjacent measuring intervals are a circular arc whose inclination and azimuth are gradually changing. The entire interval consists of several arcs with different curvatures. The method takes into account changes in bearing, with the actual shape of the well section in space. From Figure 1 know full-angle ε ∠ BCD can be ...
