摘要
采用天然气重烃富集及色质分析技术，从管琼盆地YA13－1气田和LD22－1气田的天然气中，检测到省蒲、芳烃、金刚烷等生物标记化合物，并结合其它有机地球化学资料，应用新的天然气有机地球化学研究方法，进行了气源综合对比研究，认为YA13－1气田和LD22－1气田的气源岩同为埋深大于5km的高成熟海相气源岩。对比结果还表明下第三系海相泥岩可能是写琼盆地的重要气源岩之一。
This paper uses new analysis technology of gas-biomarkers to detect biomarkers of steran, terpane, aromatic andadamantane. Combining with a lot of geochemical data, the gas-sources of YA13-1 and LD22-1 gas fields are studied insynthetical correlation. Conclusively, the natural gas mostly sourced the same marine gas-source rocks (deeper than 5,000m) with high maturity. The results of correlation suggest that marine source rocks in Lower Tertiary may be one of theimportant gas-source rocks of natural gas of Yingqiong basin.
