THE DEVELOPMENT AND APPLICATION OF FINGERPRINT PARAMETERS FOR HYDROCARBONS ABSORBED BY SOURCE ROCKS AND LIGHT HYDROCARBONS IN NATURAL GAS

Among the fingerprint parameters of light hydrocarbon,indexes of MCH and CA are developed and selected as optimum parameters for parent material type and maturity, respectively, by studying the characteristics of hydrocarbons absorbed by source rocks and light hydrocarbons in natural gas. Applying these parameters, we can identify the types of natural gas and source rocks as well as determine maturity; and make direct correlations of gas/gas and gas/source rock. This new method is considered as n efficient, simple and economical measure in identifying the origin of natural gas and estimating gas source rocks.
