| 摘 要： | 综合运用天然气组分、稳定碳同位素、轻烃组成、稀有气体同位素和伴生油生物标志物等多种指标,对孤北-渤南地区深层天然气的地球化学特征和成因类型进行了研究。结果表明,研究区天然气自西向东由油型气逐渐过渡到煤成气:渤南深洼为渤南洼陷Es4上来源的高成熟油型气;渤深4断阶则为油型伴生气;渤深6潜山和渤古4潜山均以渤南洼陷Es4上生成的高成熟油型气为主,前者混入了部分源自Es3下的伴生气,后者则混有煤成气;孤北潜山第二排山天然气由煤成气和油型气混合而成;第三和第四排山则主要为石炭二叠系来源的煤成气。成藏条件分析表明,多套气源岩、多种储盖组合和良好的运移通道,是研究区形成多种成因类型天然气的主控因素。

| Abstract: | Many indicators including the component,carbon isotope,light hydrocarbon composition,rare gas isotope of natural gas and biomarkers of associated oil were used in order to clarify the geochemical characteristics and genesis of deep natural gas in Gubei-Bonan area.It is proposed that the natural gas in the study area shows certain regularities and shifts from oil-typed gas to coal-type gas from west to east.Natural gas in Bonan deep sag is high-matured oil-type gas originated from upper Es4 source rocks in B... |
