本文以东营凹陷泥岩声波时差-深度曲线为根据,探讨了该区异常压实带的分布特征。并进一步分析了东营凹陷初次运移条件。提出东营凹陷有效生油层为老第三系沙河街组第三段,它们的主要排烃期分别为馆陶～第四系与明化镇～第四系沉积时期。初次运移的方向在平面上主要自生油中心向凹陷周缘,特别是向东北绿。距离一般不超越异常压实带顶界以上600米。
Based on the acoustic wave time-depth curve of mudstone in Dongying Sag, this paper discusses the distribution characteristics of the abnormal compaction zone in this area. And further analysis of the Dongying Sag initial migration conditions. It is proposed that the effective oil reservoir in Dongying Sag is the third segment of the Shahejie Formation in the Tertiary. The main hydrocarbon expulsion periods are from the Guantao to Quaternary and Minghua to Quaternary sedimentary periods. The direction of initial migration is mainly from the oil center to the periphery of the depression in the plane, especially to the northeast green. The distance does not exceed 600 meters above the top of the abnormal compaction zone.
