摘要:

地质和地球化学研究结果表明,东营凹陷胜北断裂带的断层活动对沙二段油气运移和聚集具有重要作用。伴随着断裂活动,沙三下亚段和沙四上亚段烃源岩生成的油气分别沿坨94断层和南北向断层垂直向上运移进入沙二段,然后以东部的南北向断裂和西部的坨94号断裂为中心,在沙二段辐射状侧向运移,并在东部的胜利村背斜和西部的坨庄背斜鞍部汇合,形成沙四段和沙三段原油的混源油气藏。

Abstract:

The geological and geochemical research results indicate that fault activities of Shengbei fault zone in Dongying Sag have an important effect on oil & gas migration and accumulation of Sha-2 ember of the Shahejie Formation. Oil and gas generated from the source rocks in the lower part of Sha-2 ember of the Shahejie Formation and the upper part of Sha-4 ember of the Shahejie Formation migrate vertically into Sha-2 ember of the Shahejie Formation along Tuo 94 fault and the northsouth fault independently during the fault activities, and then migrate laterally in Sha-2 ember of the Shahejie Formation and accumulate in the saddle of Shenglicun anticline and Tuozhuang anticline.

Key words: oil &, gas migration, Sha2 Member of the Shahejie Formation, Shengbei fault zone, Dongying Sag
