摘要

To study migration horizons downward of oil from K_1qn source rock in Sanzhao Depression, the mechanism and condition of oil migration downward was studied. It was considered that two conditions in F, Y oil lagers, they are: 1) enough high overpressure; and 2) T2 faults connected k_1qn source rock and F, Y oil lagers. Oil from k1qn source rock can migrate downward into F,Y oil layer in the end of K_1n, K_2m, and E sedimentary period under the action of overpressure. The migration areas downward of oil from K_1qn source rock and its around should be favorable areas for oil exploration in F, Y oil lagers of Sanzhao Depression.
