Title: THE CENOZOIC STRUCTURAL TRANSITION AND ITS SIGNIFICANCE FOR PETROLEUM ACCUMULATION IN DONGYING SAG,SHANDONG
Abstract: Dongying sag is a secondary structure unit of Jiyang depression, its current structural framework could be regarded as two expanding fault-fold systems controlled by Chennan listric fault zone and Lijin listric fault zone respectively, with each system consisting of four fault-anticline belts. Their evolution history could be divided into three stages as NNE-SSW extension, NW-SE extension and NNE dextral-slipping. This mechanism greatly influenced the process of hydrocarbon generation, migration and accumulation. As a result, structural traps are the most import hydrocarbon preservation units and constitute most of the reservoirs located along the fault-anticline belts.
