摘要
曲塘次凹阜宁组烃源岩与原油的族组分、碳同位素、生物标志化合物对比分析研究结果表明,饱和烃含量>非烃含量>芳烃含量>沥青质含量,并且源岩与原油各组分含量较为接近;碳同位素:非烃>干酪根>沥青质>芳烃>原油>烷烃,并且干酪根的δ^(13) C值落在原油组分的δ^(13) C构成的趋势线上或附近;源岩与原油的C_(27)-C_(28)-C_(29)甾烷的"指纹"特征比较相似,均呈现出"V"字形,并且T_m/T_s比值相差较小,表明源岩与原油具有同源性,即阜三段的原油来自阜二段烃源岩。
Using family components,carbon isotopes,biomarkers to compare and analyze the hydrocarbon source rocks and the crude oil of Funing formation in Qutang subsag.It showed that saturated hydrocarbon content>non-hydrocarbon content>aromatics content>asphaltene content,and the contents of source rock and crude oil are close to each other.Carbon isotope:non-hydrocarbon>kerogen>asphaltene>aromatics>crude oil>alkane,and theδ13 C value of kerogen falls on or near the trend line ofδ13 C composition of crude oil component.The“fingerprint”characteristics of the source rock and the crude oil in C27-C 28-C29 sterane are similar,in the form of“V”,and the difference of Tm/Ts ratio is small.It shows that source rock and crude oil have homology.The crude oil of the Fu3 member is from the source rock of the Fu-2 member.
