【摘要】 采用天然气重烃富集及ＭＩＤ／ＧＣ／ＭＳ分析技术，从天然气中检测出单、双金刚烷类化合物，并根据琼东南盆地生油岩中金刚烷指标与镜煤反射率（Ｒｏ）的实测值，建立了双金刚烷指标与镜煤反射率（Ｒｏ）数值对应关系。这对研究莺－琼盆地油气成熟度无疑是一个具重要意义的探索。更多还原

【Abstract】 Abstract The diamondoid hydrocarbons in natural gas were detected by technique of heavy hydrocarbon concentration of natural gas and MID/GC/MS analysis.On basis of measured diamantane and vitrinite reflectance of source rocks in Qiongdongna basin,the relationship between diamantane index and vitrinite reflectance ( R o)were established.Undoubtedly,it will show great significance for determining the maturity of the condensate and natural gas of Ying Qiong basin.更多还原
