Abstract:

Hydrocarbon geochemical exploration, started from ground surface geochemical exploration,has entered into the realm of down-hole geochemical exploration and 3-D geochemical exploration,and it has been playing more and more important role in regional assessment and regional exploration, 3-D detailed survey and reservoir evaluation. The development of computer technique largely improved the interpretation and evaluation technique of hydrocarbon geochemical exploration. The optimization of index, the determination and screening of anomaly,the fitting of geology-geochemistry,the tapping of information and synthetic evaluation have become the brand-new thinking of hydrocarbon geochemical exploration in present-day.
