Abstract

Abstract

There is rich resources of low mature oil in Gunan sag, Jiyang depression. The low mature oil is characterized by high content of gammacerane, predominance of phytane and low maturity. The oil shale and oil mudstone with abundant algal matter in the first member of Shahejie Formation of Lower Tertiary is considered as the source rock of the low mature oil. The oil is distributed around the source area and concentrated in the first and second members of Shahejie Formation. The fault controls the migration distance and reservoir beds. There are three reservoir models: self sourced and lateral migration, self sourced and vertical migration through fault, as well as hybrid migration. The lateral migration and charge into lithologic faulted block trap led to the single sourced accumulation inside Gunan basin, while vertical migration and charge into faulted trap caused hybrid sourced accumulation in the marginal faulted zone of the basin.
