计算井眼实际轨迹的弦步法

Chord Method for Calculating the Real Trace of Well Bore

本文将计算井眼实际轨迹的空间圆弧法分为弦步法与弧步法。用矢量代数方法导出了弦步法与弧步法两组公式并作了例算对比。认为弦步法既便于应用,又较切合实际。

In this paper the space circular are method for calculating the real trace of well bore is devided into chord and are methods.The two sets of formulas for chord and are methods are derived by using vector algebraic method and some examples are listed for calculating and contrasting.The author considers that the chord method is both convenient to use and more conform to reality.
