摘要
定向取心钻进时,在岩心表面形成标记槽,同时多点照像测斜仪便随钻测量必要的参数。最后用复位实测法或计算机计算的方法分析出地层和裂缝的产状要素。对研究裂缝走向,确立布井方案很有益处。
On drilling for directionally coring, the marking channels will form on the surface of the core and at the same time, the parameters needed may be measured while drilling with multipoint photographic dipmeter. At last, the essential factors of the occurrence of formations and fractures are analyzed by using the reset actual-measurement method and computer-processed method. It is very beneficial to re-search the fracture strike and to determine the pattern of well.
