摘　　要：碳酸盐岩储层是南堡凹陷潜山重要的勘探领域,由于受到构造、岩性等多种因素的影响,常规储层预测难度大.本文提出相控储层预测方法,通过井上精细对比,确定南堡凹陷潜山碳酸盐岩储层的优势发育段,结合古地貌确定其有利分布相带,在有利相带约束下,优选出地震平均能量属性、曲率体属性、蚂蚁体属性和谱分解属性,融合这些属性,综合预测储层发育区.通过与已钻井的对比,储层发育区与钻井资料吻合度高,证实了该方法的有效性,同时为南堡凹陷潜山的展开勘探提供了参考.The carbonate reservoir is an important exploration field in the burial hill in Nanpu sag. The conventional method of reservoir prediction is difficult to the carbonate reservoir for complex structure and lithology etc.. Here we introduce the new reservoir prediction with the facies-controlled technology and contrast the information between the wells and determine the advantage reservoir of the burial hill in Nanpu sag. We use the paleogeomorphology to determine the favorable facies belt and prefer the average energy of seismic, curvature body, ants body tracking, and spectrum decomposition. Then the favorable reservoir zones are predicted by combined attributes. The result is consistent with the true drillings, which confirmed the validity of the method and gave some references for exploration of the burial hill in Nanpu sag.
