Abstract:

In coal beds, though hydrocarbon generation potential of liptinite is much higher than that of equal amount of desmocollinite, total amount of hydrocarbon generation of desmocollinite may not be lower than that of liptinite due to its large proportion. The simulation results of Jurassic coal-measures in Yining Basin, Xinjiang show that when simulation temperature is 380~420℃, hyrocarbon generation reaches its peak stage, and hydrocarbon generation stops at the temperature 450~500℃ To compare with liptinite, desmocollinite has longer hydrocarbon generation duration.

Key words: desmocollinite, hydrocarbon generation, simulation experiment, Yining Basin
