摘　　要：应用蚂蚁体追踪裂缝技术叠合能量属性预测溶洞技术,研究了碳酸盐岩油藏缝洞空间配置关系,并利用裂缝空间连通率、类干扰和示踪剂方法,明确了缝洞空间存在差异连通。在此基础上,利用不同裂缝油井见水深度与见水时间关系及注采响应持证,进行水淹特征研究,明确了低水淹分布的有利区域。研究表明,裂缝溶洞叠合预测技术能更好地反映缝洞空间差异连通,明确缝洞动用状况,是研究剩余油分布的一种有效方法。The ant- tracking combined with energy attribute is used to study the fracture- cavern spatial configuration in carbonate reservoir. The fracture spatial connectivity rate,class- interference and tracer are applied to identify different connections in fracture- cavern space. On this basis,the relationship between water break- through depth and water- break- through time,and injection- production responses are used to study water- out and identify favorable zone with low water- out. The different connections in fracture- cavern space can be better described by fracture- cavern composite prediction technology and the fracture- cavern producing degree is intuitively obtained,which provides an effective means to identify residual oil.
