Through diagenesis, catagenesis and metagenesis, biological sources form petroleum, natural gas, and coal. These processes are controlled by organic facies. By comprehensively analyzing the geochemical condition for petroleum, natural gas, and coal productivity, this paper proposes the four end models based on maceral analysis to characterize organic facies and evaluate the petroleum, natural gas, and coal productivity potential. By utilizing multi-statistic analysis the authors develop an approach to numerical representation of organic facies, build up the organic facies type index model which computes the model value of contribution of organic facies to the genesis of petroleum, gas and coal and provide the basic method for geochemical quantitative modeling of combustible organic mineral concentration.
