针对惠民凹陷的滋镇洼陷勘探程度较低的情况,从滋镇洼陷的形成演化、基山断层活动的时空差异性和沉降中心的迁移等3个方面来刻画其构造演化史。认为滋镇洼陷形成演化可分为4个阶段,即孔店-东营阶段的3个断陷期及新近系-第四系的坳陷期;基山边界断层活动的时空差异性导致了沉降中心的迁移,形成了东西两个次洼,为下一步的勘探提供了参考。
Aiming at the low exploration level of Zi Zhen Sag in Huimin Depression, the tectonic evolution history is characterized from the three aspects of the formation and evolution of Zi Zhen Sag, the spatial and temporal differences in the activities of the Jishan fault and the subsidence center. The authors think that the formation and evolution of ZiZhen depression can be divided into four stages, ie, three depression facies in Kongdian-Dongying stage and the depression period of Neogene-Quaternary. The time-space difference of fault activity in the basement hills leads to the subsidence center The formation of two sub-depression things, for the next exploration provides a reference.
