摘　　要：综合利用薄片、岩心、测井资料、实测物性资料与试油产能等资料对储层特征进行研究,建立了湖相碳酸盐岩储层综合分类评价标准并对有利储层进行了预测。通过对岩石类型、沉积相类型、储集空间特征及成岩作用特征进行研究,明确了湖相碳酸盐岩储层基本特征。湖相碳酸盐岩储层物性受沉积相、岩石类型以及成岩作用的影响。分别从沉积相、岩石类型、岩石优势成分及成岩作用方面对储层物性的影响进行分析,然后按照对物性的贡献程度进行"A"、"B"、"C"3类评价并赋予对应的权重值,再根据综合得分对储集层进行分类,结合物性资料与试油资料,最终建立湖相碳酸盐岩储层综合分类评价标准。借助测井资料对各类储层进行识别,预测了渤海湾盆地济阳坳陷邵家洼陷沙四段湖相碳酸盐岩有利储层的展布范围。Microscopic feature of lacustrine carbonate reservoir for the fourth member of Shahejie Formation（Es4）of Shaojia Sag is studied based on the core,thin sections,logging data,measured property and producing test data.An integrated classification and evaluation criterion is built to predict the favorable reservoir distribution for lacustrine carbonate reservoir.Characteristics of carbonate rocks,such as rock types,facies,reservoir space and diagenesis,control lacustrine carbonate reservoir property directly.After analyzing and evaluating these factors on the reservoir property,＂A＂,＂B＂,＂C＂,are graded respectively according to their contribution to rock properties.Reservoir is later classified into different petrofacies according to their evaluation result.Combined with rock properties and producing test,a classification and evaluation standard of lacustrine carbonate reservoir is established.The favorable distribution of lacustrine carbonate reservoir in the Es4 of Shaojia Sag of Bohai Bay Basin is predicted through well log data.
