Controlling factors on the oil distribution in the edge of the Sanzhao depression
The area of the South Songzhan is a structural nose,which is located in the edge of the Sanzhao depression,the northern of the Songliao Basin.One part of it is located in the oil source area,and the other part is located outside the oil source area.The study on the oil-source correlation,migration mechanism and main controlling factors for the F,Y oil layers in the South Songzhan reveals that the range of oil source,the mount of hydrocarbon provided by the source rock,the degree of ancient overpressure in the first member of Qingshankou formation and the locations of the traps and the sandbodies development determine the distribution of F,Y oil inside the oil source area.Outside the oil source area,the mount of hydrocarbon supplied and whether traps are located near the migration paths linked by the T2-faults and the sandbody control the distribution and the location of F,Y oil.The prospective targets in the South Songzhan are the traps near the T2 source faults,in the faults” uplifted walls and near the oil and gas migration paths.
