摘要
根据目前琼东南和莺歌海盆地油气的物理性质、化学组成,将原油分成三种类型:石蜡型、芳香-石蜡型和石蜡-环烷型;将天然气分为三种类型:伴生气、煤成气和生物成因气.利用甾萜、异戊.间二烯烷烃、碳同位素和轻烃等油(气)/岩对比指标,结合地质条件,确定了各类油(气)的烃源岩,进而讨论了各烃源岩层的有机质丰度、类型、成熟度等特征.
Grude oils in Qiongdongnan and Yinggehai basins are subdivided in light of their physical properties and chemical compositions into paraffinic,aromatic-paraffinic and paraffinic-naphthenic types,and matural gases there into associated, coal derived and boigenic.The relative source rocks of the oils&gases are determined upon the base of geochemic analyses such as of steranes,terpanes,isoprene,carbon isotopic values and light hydrocarbon and geologic conditions,and studied with emphasis on TOC,Kerogen type and maturity.
