本论文对井眼轨迹反演理论及方法作了简要的分类，介绍了几种目前常用的井眼轨迹反演方法及其特点；分析了影响井眼轨迹的主要因素；综合考虑地层和钻头的各向异性钻井特性，建立钻头与地层相互作用模型，基于钻柱底部组合力学模型设计出一条井眼轨迹；制作了基于3DS Max的井眼轨迹演示动画。

The scale-value, which is converted from the bore-hole strain, by nse of the observed values in tidal frequency band of the bore-hole strain and the elastic coefficients of the bore-hole corescan can be used for coverting non-tidal variation of the bore-hole strain into variation of the non-tidal stress of the same stratum.

顾梦林 ，杨毅，骆鸣津利用钻孔应变观测值中潮汐频段部分和钻孔岩芯的弹性系数，将钻孔应变换算为地层应力的格值，用此格值可将钻孔应变的非潮汐变化换算成该地地层的非潮汐应力变化。
