应用油气组成、生物标志物与碳同位素分析资料对渤中坳陷QHD30-1构造油气地球化学研究表明,该构造馆陶组原油为正常成熟度原油;沙一段凝析油为早期低熟油被后期高成熟天然气气侵之后形成的;孔店组原油为低熟油。油源对比表明,该构造低熟油与正常成熟度原油主要来自构造周围沙河街组烃源岩,而沙一段高成熟天然气来自秦南凹陷高成熟烃源岩。综合该区构造、沉积与地球化学特征,对该区油气多期充注过程进行了分析。 Application of hydrocarbon composition, biomarkers and carbon isotope analysis data to the oil and gas geochemistry of QHD30-1 in the Bozhong Depression shows that the crude oil from the Taohe Formation in the Tectonic Museum is normal maturity crude oil; After the formation of high-mature natural gas after the invasion; Kongdian group crude oil is low-cooked oil. The comparison of oil sources shows that the crude oil with low maturity and normal maturity mainly come from the source rocks of Shahejie Formation, while the high matured gas from the first part of Shahejie Formation comes from the highly mature source rocks of Qinnan depression. Based on the tectonic, sedimentary and geochemical characteristics of this area, the multi-period filling process of oil and gas in this area was analyzed.
