应用逐步生烃方法,结合EasyRo%计算,对东营凹陷利津洼陷利562井沙三段1962.6m黑色泥岩处理得到的湖相I型干酪根进行了封闭恒温体系下的热模拟实验。通过对各阶段累积抽提物中各族组分的定量分析,对抽提物中有机族组分变化进行了描述,并指出抽提物不能代表储层中未经降解的原油;以利983井3195.9～3202.8m沙三段成熟原油为基准,将Ro为1.17%时累积抽提物中的族组分比例配分得到的可代表普通成熟原油的热模拟原油,经轻烃校正后得到了此阶段该烃源岩每减少1克有机碳最大可生成766.7mg原油。在此基础上,结合前人实验方法,提出了新的精确度较高、成本较低且可行性较强的烃源岩生油量计算新方法,并推导出实际计算公式。
Based on the EasyRo% calculation and the calculation of EasyRo%, the thermal simulation experiment of lacustrine Type I kerogen obtained from the treatment of 1962.6m black mudstone in the third member of Shahejie Formation of Li 562 in Lijin Sag, Dongying Depression, was carried out. Based on the quantitative analysis of the components of each ethnic group in the accumulated extracts from different stages, the changes of the organic components in the extracts were described. It was pointed out that the extracts could not represent the crude oil that has not been degraded in the reservoir. Well 3195.9 ~ 3202.8m sand third mature crude oil as a benchmark, Ro is 1.17% when the cumulative extract of the proportion of components in the family can be drawn from the common mature crude oil thermal simulation of crude oil, light hydrocarbon corrected this The stage of the source rock for every 1 gram of organic carbon can generate a maximum of 766.7mg crude oil. On this basis, combined with the previous experimental methods, a new method for calculating the oil production of the source rock with high accuracy, low cost and high feasibility is proposed and the practical calculation formula is deduced.
