作者应用生物标记物分析技术 ,结合其它地球化学资料 ,对南祁连石炭系碳酸盐岩和泥岩进行了有机质生源构成、沉积环境、成熟度和生油潜力等方面的初步研究。研究结果表明 ,该烃源岩发育的沉积环境为海相还原环境 ,有机母质主要为低等水生生物兼有高等植物的混入 ,有机质类型为腐殖 腐泥型和腐泥型 ,有机质丰度高 ,成熟度较高 ,具有形成油气的有利条件 Based on biomarker analysis and other geochemical data, the authors conducted a preliminary study on the composition of organic matter sources, sedimentary environment, maturity and oil-generating potential of Carboniferous carbonate rocks and mudstones in southern Qilian. The results show that the depositional environment of the source rock is the marine environment, the organic parent material is mainly composed of lower aquatic organisms mixed with higher plants, the organic matter types are humic sapropel type and sapropelic type, and the organic matter abundance is high , High maturity, with the favorable conditions for the formation of oil and gas
