The association of strata and faults control the migration and enrichment of Tertiary hydrocarbon.

地层与断层的组合关系制约着上第三系油气运移方向和富集位置。

So the migration related to fractures is the main mechanism of hydrocarbon expulsion of the Low Tertiary source rocks in the Dongying Depression.

因此，与裂缝相关的油气运移机制是东营凹陷下第三系烃源岩排烃的主要机制。
