| 摘 要： | 松辽盆地大情字井地区油气勘探重点已由构造油藏转为隐蔽性岩性油藏,非主力油层青二段成为今后主要勘探目标。对区域地质资料、岩心资料、重矿物、地震以及测井曲线等资料进行综合分析,确定大情字井地区青二段油层主要为三角洲前缘—前三角洲沉积体系,并对主要沉积微相类型进行了识别,分析了主力小层沉积微相与砂体展布规律。砂体类型以水下分流河道和河口坝为主,其中,水下分流河道呈条带状SW—NE向展布,向东逐渐减薄,受河道侧向摆动影响,砂体呈叠置或切割分布,形成复合条带状砂体和断续砂。

| Abstract: | The key target of exploration activity in Daqingzijing area has changed from structural pool to subtle lithologic pool, and the non-major reservoirs of Qing 2 formation will become the main exploration target in the future. This paper makes a multidisciplinary analysis of regional geology, core data, heavy minerals, seismic data and logs, determines that the Qing 2 reservoir in Daqingzijing area belongs to delta front-prodelta depositional system, identifies the types of major sedimentary microfacies, and a... |
