Petroleum secondary migration pathway in Mesozoic period,Ordos Basin;

On the premise of traps and oil sources,favorable migration pathway is the background for the forming of the reservoirs;the features of fluid dynamics are closely related to the distribution of the reservoirs;the reservoir critical property is the deciding factor for the.

Results demonstrate these area features short distance to oil source, good combination of oil reservoir and cap, smooth oil & gas migration channel, finely accommodated relationship between structures forming period and oil & gas migration, as are all favorable igneous reservoir forming conditions.

Thick-bed sand body genesis and oil-gas migration pathway in the forth member of Xujiahe Formation of Upper Triassic in the central Sichuan Basin;
