摘　　要：岩心定向是确定钻孔内地质结构面倾向及倾角,采用岩心定向矛(定向技术)对钻孔内的地质结构面进行岩心定向,通过测量岩心定向参数,返算出定向岩心的地质结构面原始倾向及倾角,直接应用在地质剖面图中进行地质解译,解决了地质剖面图绘画倾向有多解的实际问题。Core orientation is to determine the inclination and dip angle of the geological structural plane in the borehole.The core orientation spear(orientation technology)is used for core orientation of the geological structural plane in the borehole.By measuring the orientation parameters of the core,the original inclination and dip angle of the geological structural plane in the directional core are calculated,which are directly applied to the geological interpretation in the geological section map.It solves the practical problem that the drawing tendency of geological section has multiple solutions.
