摘要
应用GC/MS分析技术,系统研究了柴达木盆地西部南区绿参1井烃源岩地球化学特征,通过对绿参1井烃源岩总有机碳、生烃潜量、有机质类型、成熟度等研究,结果表明:N12层段为一般烃源岩,深部E32—E13层段属很好的烃源岩;烃源岩抽提物中正构烷烃分布特征变化较大,有单峰型和双峰型;烃源岩具有明显的植烷优势,除部分层位伽玛蜡烷含量较低外,总体上伽玛蜡烷较高,指示烃源岩沉积环境还原性较强。
By using the analytical techniques of GC/MS, geochemical characteristics in LC 1 well of source rocks in the south area of western Qaidam basin are analyzed. The analyses of TOC, hydrocarbon generating potential, and types of organic matter and maturity reveal that： in N1^2 segment, the source rock is common in quality; in the segments of E3^2-E3^1 ,the source rock is high quality; the distribution characteristics of n-alkanes from the source rocks change largely, there are single peak and double peak; there are obvious phytane advantages, and the abundance of gammacerane is high as a whole except that some segments have low abundance of gammacerane, indicating a strong reducing environment of deposition.
