Abstract: Through analysis on the industrial indexes of oil shale in Triassic Yanchang Formation of He 1 well in Ordos basin, it is found that there is a good positive linear relationship between hydrocarbon-production rates in the oil shale. Based on the analytical results of 70 oil shale samples, the average oil production rate is 5.9%, gas production rate is 3.7%, and total oil and gas production rate is 9.6%. Among them, gas production rate accounts for 38.5% of the total hydrocarbon production rate. The data suggest that gas production rate is high and is a key index in evaluation of oil shale.

Key words: Ordos basin, oil shale, industrial index, gas production rate, hydrocarbon production rate
