Shale gas resources have a great potential in the southeast of Ordos Basin，the lack of the hydrocarbon generation potential evaluation of Shanxi Formation restricts the objective evaluation about resource rocks potential in this zone.Hydrocarbon products and hydrocarbon generation potential of Shanxi Formation were analyzed by pyrolysis experiments.The following results were obtained，(1)methane and non-hydrocarbon gases show similar yields characteristics，heavy hydrocarbon gas C2-5 and liquid hydrocarbons show similar yields characteristics;(2)liquid hydrocarbon reaches the peak yield as RO between 0.80%-1.08%,heavy hydrocarbon gas reaches peak yield as RO between 1.47%-1.81%.When RO exceeds 3%，heavy hydrocarbon gas is almost completely cracked，the drying coefficient is close to 1;(3)pyrolysis experiments show that the second member reservoir is a better source rock.Geochemical data of shale gas wells further confirmed that the hydrocarbon generation potential of second member reservoir is much larger than that of first member reservoir.It is concluded that the second member reservoir is a favorable exploration stratum of continental shale gas in Ordos Basin.
