摘　　要：旅大10-5构造为渤海湾重点勘探区块,后续勘探工作部署意义重大。从岩屑、岩心实验出发,以实际实验数据从孢粉、藻类、介形三个维度分析东营组古生物特征,还原古沉积环境。采用铸体薄片、X衍射等方法分析储层岩性、孔隙类型、物性,并创新性探讨物性与泥质含量相关性。评估东营组勘探潜力和开发潜力,为后续勘探开发部署提供指导。LD10-5 structure is a key exploration block in Bohai Bay,and the deployment of subsequent exploration work is of great significance.Based on the experimental data of rock debris and core,the paper analyzes the paleontological characteristics of Dongying Formation from three dimensions of palynology,algae and mesoform,and restores the paleodepositional environment.The lithology,pore type and physical properties of the reservoir are analyzed by the methods of cast thin section and X-ray diffraction,and the correlation between physical properties and shaliness content is innovatively discussed.To evaluate the exploration potential and development potential of Dongying Formation and provide guidance for the subsequent exploration and development deployment.
