The Characteristics of Neozoic Structural Evolvement of Linnan Area in Huimin Sag

The cenozoic structural evolvement sections of the well tie projection in the east and west of Linnan area of Huimin sag are drafted in the paper, using the principle of decompaction compensation. The Neozoic structural characteristics and evolvement sequences are summarized systematically. The structural evolvements between the east and the west of Linnan area exist time differences. On the one hand, the southwest gentle slope belt has behaved the stable slope since the Cenozoic. On the other hand, Qudi horst is tilted strongly from the first chron of Shahejie age to Dongying age. Finally, the conclusion can be arrived at: Xiakou fault controlled the structural evolvement of Linnan area, and the detachment faults in the capping bed developed little, which provides the hydrocarbons with the better conservation condition in Linnan area.
