| 摘 要： | 东营凹陷断块油气藏发育广泛，沙河街组是勘探开发的重点。对东营凹陷沙河街组断块油气藏基本地质特征进行研究，分析断块油气藏成藏主控因素，从而指导油气勘探。东营凹陷沙河街组断块油气藏主要分布在中央背斜带、北部陡坡带和南部缓坡带，层位上分布在沙一段、沙二段和沙三上亚段。研究认为，东营凹陷沙河街组断块油气藏的聚集和分布受烃源岩、断层、异常压力和储层物性等因素的控制。沙四上亚段和沙三下亚段的优质烃源岩为油气成藏提供了良好的物质基础；异常压力为油气运移提供动力；断层不仅作为油气运移的通道，还控制着圈闭的形成；储层物性控制着油气藏的分布，孔隙度大于15％．渗透率大于10×10^-3μm^2的储层有利于油气聚集．

| Abstract: | Fault-flock reservoirs are extensively distributed in Dongying Depression,and Shahejie Formation is the highlight of exploration and exploitation.According to the statistical analysis of the geological features of fault-block reservoir in Shahejie Formation of Dongying Depression,main controlling factors of fault-block reservoirs are studied for oil-gas exploration.The fault-block reservoirs of Shahejie Formation in Dongying Depression are mainly distributed in the central anticlinal belt,the northern steep... |
