| 摘 要： | 热解参数S1是表征泥页岩中游离烃含量的关键参数,其准确性直接影响页岩油资源潜力评价结果的可信度,受实验分析技术的影响,测得的S1需要进行轻、重烃损失校正。通过对三塘湖盆地芦草沟组来源原油进行热解分析,初步证明热解参数S1中的重烃进入了S2中,进一步通过对抽提前、后热解实验参数的对比,确定了重烃校正系数为1.2。通过对比成熟度及类型均一致的松辽盆地青山口组一段泥岩的校正系数变化曲线,确定芦草沟组泥岩S1的轻烃校正系数为0.8。综合实验值及轻、重烃校正系数,确定芦草沟组泥页岩热解参数S1校正后是3S1。

| Abstract: | One of pyrolysis parameters,S1 is a key parameter for free hydrocarbon content in shale oil characterization and its accuracy can directly affect the credibility of the oil shale resources potential evaluation result.Influenced by experimental analysis technology,the measured S1 needs light and heavy hydrocarbon loss of correction.Through parameters comparison before and after pyrolysis analysis of Lucaogou formation in Santanghu basin,the correlation coefficient of heavy hydrocarbon has been determined to be 1.2.By comparing the maturity and the correction coefficient curve of mudstone of Qingshankou formation in Songliao basin,the correlation coefficient of light hydrocarbon in Lucaogou formation in Santanghu basin has been determined to be 0.8.Through comprehensive analysis of the experimental value and light and heavy hydrocarbon correction coefficients,the pyrolysis parameter of mud shale S1 in Lucaogou formation after correction is 3 S1. |
