Abstract:

Based on the extensive surface natural asphalt, oil and gas seepage hydro-chemical property and asphalt evolution stage, integrated with regional tectonic, thermal degradation, preservation condition and the correlation of known oil and gas field, it is pointed out the preservation and potential structure study should be done on the fault-depression at Mesozoic and Paleozoic outcrop areas. It is in the area with good preservation and thermal action is procreating that fault trap and organic reef gas pool will be found. It is not favorable area to find gas field in the area, which the natural asphalt commonly occurs and oil and gas seepage and extensional fracture are developed.

Key words: natural asphalt, hydrocarbon seepage, oil and gas distribution, fault tram, gas reservoir, Southern China
