摘要
应用生物标记物分析技术,结合其他地化分析资料,对广西的合浦和宁明盆地的第三系可能生油岩,进行了有机质生源构成与沉积环境、成熟度及成油潜力等方面的初步研究。研究结果表明,两盆地第三系暗色泥岩的有机母质利于成油,丰度高,保存条件好,具备了形成低熟油和成熟油的条件。地质条件与已发现油气的百色盆地类似,因此是两个很有希望找到油气的接替盆地,值得继续深入地进行勘探。
The sedimential environment and original composition,maturation level of organic matter and hydrocarbon generation potential of possible Tertiary source rocks in Hepu and Ningming basins in Guangxi are discussed,by using the biomarker analysis technique and combined with other geochemical data.The result of study suggested that the Tertiary dark claystones in the two ba- sins have the characteristics of good organic matter type for oil generation, high concentration of solubale organic matter and good preserving condition for organic matter.Therefore,these dark claystones have reached the condition of forming immature and matured oils.Hepu and Ningming basins have the high potentiality for found petroleum,as they are similar to Baise basin in geolo- gical condition.
