摘　　要：油田开发中后期剩余油分布异常复杂,GPTMap软件帮助构建一体化数据库,在识别沉积微相类型、录入沉积微相代码、绘制平面图层等工作基础上,以松辽盆地大庆杏树岗油田杏三区东部白垩系姚家组一段葡萄花Ⅰ组油层1—3小层(葡Ⅰ1—3小层)为例,进行了沉积微相类型、特征、组合模式和不同地质时期沉积微相平面展布特征的精细研究。结果表明,葡Ⅰ1—3小层为浅水湖泊三角洲沉积,主要发育三角洲分流平原和三角洲内前缘2种沉积亚相,含11种沉积微相类型;建立了测井微相模式,总结了7种沉积微相组合模式,绘制了平面底图、砂厚等值线图、沉积微相平面图等基础图件,丰富了地质数据库,提高了工作效率,对油田进一步开发具有指导意义。The distribution of residual oil has been increasingly complex in the middle-late oilfield development stage. This work used the GPTMap software to build an integrated geological database for the Putaohua [ group oil layer 1-3 sublayers （Pu Ⅰ 1-3 sublayers） of the Cretacous Yaojia Formation in the eastern Xing-3 area in Xingshugang Oilfield of Daqing, Songliao Basin. On the basis of identifying the types of sedimentary facies, sedimentary facies＇ codes input and drawing geological map, we conducted fine study on the types, characteristics, combination patterns and distribution of the sedimentary microfacies in different geologic periods. The results show that the Pu Ⅰ 1- 3 sublayers were shallow-water lake delta sedimentation, mainly developed distributary plain facies and inner front facies. They contained 11 types of sedimentacy microfacies. The logging microfacies patterns can be summarized to seven types of combination patterns. In addition, base maps, contour maps of thickness of sand bodies and the plane distribution maps of sedimentary microfacies were drawn. This work has enriched the geological database and improved the work efficiency, which has practical significance for further development.
