钻孔轨迹的预测与施工控制

Prognosis of core traces and control of construction

运用拉格兰图解原理,建立钻孔轨迹空间位置的预测方法,即根据已施工孔段的钻孔偏斜趋势来预测后继施工孔段的空间位置,为确定后继孔段的施工是否需要采取相应的控制措施提供重要依据。

This article applies the principle of Laglan diagram to set up a method of prognosis of the core traces and spacial location. It means that the tiltin trend of the constructed core section can be used to calculate the spacial location of the following core section, and to give an important basis for the determination of whether associated control measures are needed or not in the following construction.
