摘　　要：介绍了利用FMI/XRMI在碳酸盐岩水平井中识别裂缝的原则。对解释的裂缝产状进行了后续处理与分析,开展了裂缝与井眼关系综合解释方法研究。探讨了通过求取裂缝在闭合方位面上投影斜率和求取裂缝在水平面上投影来确定裂缝与井眼的位置关系的方法。将该方法应用于塔里木盆地Ma-A水平井,对该井裂缝发育情况作了综合解释,使得该井分段酸压裂成功进行,提高了储层采收率,同时也为评价井眼钻遇裂缝的效率提供了基础图件及数据。Introduced are the fundamentals to identify fractures in carbonate horizontal well using FMI/XRMI images. Processed and analyzed are the interpreted fractures dip and orientation. Studied are the comprehensive interpretation methods for relationship between fracture and the horizontal well. Put forward is a method to determine the rlation between the fracture ＆ horizontal boreholes by calculating the projective slopes of the fractures in closure azimuth plane, and calculating the projection of the fractures in horizontal plane. This method is used to interpret fracture development in horizontal well Ma-A in Tarim basin. The interpretation results make the segmented acid fracturing successful, and improve the reservoir yield. It provides basic data for acid tool depth decision and supplies diagram and data for evaluating the efficiency of drilled well.
