Molecular carbon isotopic geochemistry records of thermal cracking in the palaeo-reservoir of well Shunnan 1 in Guchengxu Uplift, Tarim Basin

  • 摘要: 塔里木盆地古城墟隆起顺南1井高成熟度轻质原油被认为是典型的热裂解残余油。研究揭示顺南1井原油中高丰度的苯系物和丰富的稠环芳烃,是其在地质历史上经历强烈热裂解的次生产物之一;苯系物应为热裂解、环化、芳构化过程的中间产物,而稠环芳烃可能指示了缩聚过程。烃类分子裂解—缩聚过程诱发的碳同位素分馏,不仅使顺南1井原油正构烷烃分子碳同位素较下古生界含油气系统中正常原油的重8‰~10‰,而且烷基萘系物分子碳同位素也比下古生界含油气系统中的正常原油重6‰~8‰。研究结果进一步实证了与裂解成因相关的芳烃分子及其稳定碳同位素组成是判识深层—超深层油藏是否经历热蚀变的有效手段,其对于准确评估深层—超深层油气相态与资源格局具有重要意义。
