摘　　要：运用矿物学、钻测井资料和地震信息,分析了济阳坳陷渤南洼陷南斜坡古近系Es2/Es3之间Ⅱ级不整合样式及油气运聚特征.结果表明:渤南洼陷南斜坡古近系Es2/Es3不整合为无黏土层结构,根据不整合上下地层产状和岩性叠置关系,可形成4种不整合组构样式.不整合组构样式平面分布规律控制了油气呈线性运移、局部富集的展布特征.Taking Es2 /Es3 class Ⅱ unconformity in Paleogene of the south slope zone of Bonan Sag in Jiyang Depression as an example,the modes of class Ⅱ unconformity and the feature of hydrocarbon migration and accumulation are analyzed based on mineralogy,drilling and logging data and seismic information. The results show that Es2 / Es3 class Ⅱ unconformity structure is a no-clay structure. There are four types of unconformity combination modes according to the occurrence and the lithology superposition relation of the strata above and below the unconformity surface. The plane distribution of the unconformity combination modes controls the hydrocarbon migration and accumulation feature of linear migration and local enrichment.
