JIYANG BRUSH STRUCTURAL SYSTEM AND ITS RELATIONSHIP WITH OIL AND GAS

After discussing the characteristics of Jiyang Brush Structural System and the distribution of oil and gas in this area,the paper analyses the relationship between the Brush Structural System and hydrocarbon from the viewpoint of the formation and evolution of the Jiyang Brush Structural System.The paper points out that Jiyang Brush Structural System resulted from several rotations of the West Shandong Uplift that were caused by large scale strike slip of Tan-Lu Fracture.And the activity of teh Jiyang Brush Structural System controlled the distribution,migration and accumulation of hydrocarbon within it.Oil and gas are enriched at the diverging area of the brush structural system and are poor at the converging area.
