The Study on Hydrous Pyrolysis Experiments of Coal-Measure Source Rocks in Ordos Basin

Abstract:

Through the hydrous pyrolysis experiments of coal-measure source rocks in Taiyuan formation in Ordos Basin with different mediums from 250 °C to 550 °C, with a stepwise heating stage of 50 °C, the characteristics of gas and liquid products are discussed systematically in this paper. The results show that the change rule of hydrocarbon productivity of coal with temperature is similar to mudstone. Total hydrocarbon productivity and gas hydrocarbon productivity increase with temperature rise. Liquid hydrocarbon productivity increases with temperature rise first and then decreases. The peak yield of oil of coal appears at the heating temperature 350 °C, mudstone at 375 °C. The peak yield of mudstone lags behind. The non-hydrocarbon gas productivity increases with temperature rise. The non-hydrocarbon gases are carbon dioxide, nitrogen gas and oxygen mainly. The productivity of carbon dioxide is significantly higher than other non-hydrocarbon gas productivities. The main hydrocarbon gas is methane. The productivity of methane increases when temperature rises. And the productivity increases obviously after 400 °C.
