Pattern of Oil and Gas Accumulation in the South and Middle Part of Zhedong Central Anticline Area

The trap in the south and middle part of Zhedong Central Anticline Area all can form oil and gas accumulation because of the good condition of the source rocks,the reservoirs and the covers.And then,the pattern of oil and gas accumulation in the south and middle part of Zhedong Central Anticline Area becomes the pattern of oil and gas conservation.Because the oil and gas conservation was controlled by the late shear fault, the pattern of oil and gas accumlation in the south and middle part of Zhedong Central Anticline Area can be studied by analyzing how the oil and gas accumulation were destroyed by the late shear fault.
