In order to explore the petroleum reservoir forming laws in Nanpu Sag, the research method of the spa- cial distribution relation between the petroleum and its migration-accumulation process is adopted to study the process and their main controlling factors. The obtained processes for different horizons can be divided into two parts： vertical migration and lateral diverting accumulation. The former is mainly controlled by the following two factors ：1）faults in the oil source rock are the principal transporting path ways for the oil and gas migration ; 2）size of the connected fault thicknesses of the regional caprock controls the enriched or accumulated positions of the pe- troleum. The latter is generally dominated by the following three factors：1）strata with high sandstone-formation ra- tios on and beneath the regional caprock are favorable for oil and gas to migrate laterally；2）positive structures near the faults connected with the oil source rock are prone for oil and gas to accumulate；and 3）different combined forms of the faults result in the different degrees of petroleum accumulation.
