Abstract:

According to formation, evolution and structural characteristics of Shaihan Sag, structural development and petroleum geological characteristics of the Sag are discussed, and the accumulation of oil/gas and the relation between fault and oil/gas are descried. It is pointed out that friction heat due to faulting activity and volcanic eruption along the faulty make the geothermal gradient rise in the area, which is favorable for organic matter to transform into hydrocarbon.

Key words: Tectonic transport, Remote sensing, Hydrocarbon potential
