摘要
通过对鄂尔多斯盆地何1井三叠系延长组油页岩工业指标分析,发现油页岩产油率与产气率具有良好的线性关系,随着产油率的增加,产气率呈线性增加。据70件油页岩样品分析结果,平均产油率为5.9%,平均产气率为3.7%,平均油气产率为9.6%,产气率占油气产率的38.5%。说明产气率在油气产率中占有较大比重,是油页岩工业品质评价的重要指标。
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.
