| 摘 要： | 根据层序地层分析的基本思想, 从单井岩心的成因相解释出发, 在渤南洼陷沙二段详细分层对比的基础上, 研究了扇三角洲沉积体系, 讨论了主要储集岩特征。研究结果表明, 渤南洼陷内部沙二段发育较好, 边缘受凸起抬升和物源供给缺乏的影响, 普遍缺失底部砂层; 该区沙二段是在浅水湖泊沉积的背景条件下, 以扇三角洲体系为主的沉积组合, 在研究区西部和北部, 小规模发育近岸水下扇沉积体系; 沙二段储集岩以扇三角洲前缘的砂岩、含砾砂岩及粉砂岩为主, 东南部储集层物性较好, 与油气聚集的关系密切。

| Abstract: | According to the theories of sequence stratigraphy,with the object of understanding genetic facies of the well cores,a study of fan delta sedimentary system has been made to discuss the main characteristics of reservoir rocks based on subdivision and correlation of the second member of Shahejie Formation.The results suggested that this member is well developed in the interior of Bonan sag,but lacks its lower part in the marginal parts because of uplift and insufficient supply source.In the study area,the se... |
