To study oil-gas accumulation difference of Fuyang oil layers between the east and the west of Daqing placanticline, by the study of oil-gas migration conditions difference of K₁qn₁ source rock into Fuyang oil layers, oil-gas expelled from K₁qn₁ source rock was considered to migrate mainly downward into Fuyang oil layer in the east of Daqing placanticline, oil-gas expelled from K₁qn₁ source rock can not only migrate downward into F,Y oil layers in the west of Daqing placanticline oil-gas can but also migrate upward into S,P,G oil layers. By the study of difference in oil-gas migration downward force, distance and horizons, ancient overpressure value of K₁qn₁ source rock in the east of Daqing placanticline was considered to be bigger than that in the west.
