| 摘 要： | 根据对东营凹陷油气储层成岩规律的分析，结合层序地层单元的分布构架，发现成岩演化过程所决定的成岩相特征与层序地层分布有密切相关性。阐述了在层序界面附近和层序体内部成岩作用发生的一般规律，认识到油气储层的储集性受成岩相和成岩层序控制。认为东营凹陷古近系近期勘探所取得的一系列成果，与成岩作用的差异性有关。将储层储集特征和成岩层序特征有机结合,合理地解释了凹陷内油气富集规律。说明该区油气勘探工作必须有的放矢，科学布局，循序追踪，才能获得最佳勘探效果。

| Abstract: | According to a research on oil-gas reservoir diagenetic characteristic and spreading block frame of sequence stratigraphy,the high-degree association was found between diagenetic facies charactertic which was decided by the process of diagenetic evolution and spreading of sequence stratigraphy.The ordinary rule of diagenasis near the boundaries and in the internal of a sequence was introduced in this article.It can be distinguished that the reservoir characteristic was controlled by diagenetic facies and diagenetic sequence.It was thought that some of success of exploration in Lower Tertiary in Dongying Sag was connected with differences of diagenesis.The reasons of oil-gas richness was reasonably explained by the study on reservoir characteristic and diagenetic sequence.The results are that oil exploration must provide with specific aim,which was discovered by scientific way.So the best effectiveness would be acquired for exploration. |
