HYDROCARBON GEOCHEMICAL FIELD EFFECTS AND THEIR APPLICATIONS

Proceeding from the concept of the hydrocarbon geochemical field and its effects,the influent factors of the formation and evolution of the hydrocarbon geochemical field was analyzed.Origin of hydrocarbon geochemical field effects and their concrete expression over an oil and gas accumulation were also discussed.There is obvious relationship between hydrocarbon geochemical field in the surface and oil and gas accumulation in the deep.
