| 摘 要： | 根据地震作用过程，阐述了震积岩在岩心中的识别标志，建立了东营凹陷沙三段、沙四段碎屑震积岩的标准序列。分析结果表明，东营凹陷沙三段、沙四段沉积时期地震活动强烈且具周期性，并波及范围广。研究发现地震对地层的改造作用能改善砂岩储层的储集物性。

| Abstract: | cognition marks of the seismite in cores are analyzed and the clastic seismite standard sequence system in Sha3 and Sha4 member ( Es3, Es4 ) of Dongying sag is established based on the seismic action process. The analytic results present that the seismic movement was violent and has periodicity during the depositional stage of Es3 and Es4 in Dongying sag, and its sweep range is wide. It is found that seism process can improve sandstone reservoir quality. |
