Abstract: The authors discussed petroleum generation, evolution, migration and reservoir forming conditions and its controlling factors of Pai 2 well section in Junggar Basin. Based on the basin evolution histories and conduit frame work and potential source-rock, we studied not only the evolution of the energy fields but also the kinetic and dynamic processes, by integrated geological, geophysical and geochemical means and computer modeling techniques. Detailed oil-to-source correlation showed that oil/gas of Pai 2 well section mainly originates from “coal seam” of Jurassic in south Sikeshu sag. The geologic factors and the geologic function, such as petroleum generation, migration and accumulation and so on, were controlled by Himalayan neotectonism. The accumulation model of Pai 2 well section was attributed to late, shallow, longdistance and fast injection.

Key words: Junggar Basin, oil-to-source correlation, neotectonism, mechanism of petroleum accumulation
