对中国１０个盆地不同沉积环境的４２个凝析油进行的ＧＣ、ＧＣ－ＭＳ、ＧＣ－ＡＥＤ及碳、氢同位素分析表明：海相、淡水、微咸水湖泊相、半成水湖泊相、咸水湖泊相凝析油以及沼泽相凝析油具有不同的有机分子和生物标记化合物组合以及碳氢同位素分布。海相凝析油富含异构烷烃和烷基环戊烷轻烃系列、硫芴及降姥鲛烷；贫二环倍半萜尤其是升锥满烷；Σ烷基环己烷／Σ正构烷烃值较大，具有较重的δＤ值和较轻的δ￣（１３）Ｃ值，前者平均－２９．８‰；后者平均－１１９．７‰。陆相咸水、半咸水湖相凝析油富含含硫化合物尤其是硫芴；Σ烷基环己烷／Σ正构烷烃值略小于海相凝析油；具明显植烷优势；具有较重的δ￣（１３）Ｃ值和δＤ值，平均值分别为－２５．５‰和－１２１．２‰，全烃色谱具继承性微弱奇偶优势。微咸水、淡水湖相凝析油相对富含二环倍半萜尤其是锥满烷和升锥满烷及芴。沼泽相凝析油富含甲苯、甲基环己烷（轻烃）、二环倍半萜及氧芴；尚检出有按叶油烷等陆相生标化合物；Σ烷基环己烷／Σ正构烷烃值较小，具有姥鲛烷优势；δ￣（１３）Ｃ值较重，平均值为－２６．５‰。
GC, GC-MS, GC-AED and carbon and hydrogen isotope analyzes of 42 condensate oils from different sedimentary environments in 10 basins of China show that marine, freshwater, brackish water, semi-water lacustrine, Polar phase condensate and swamp condensate have different combinations of organic molecules and biomarker compounds as well as hydrocarbon isotope distribution. The marine condensate is rich in isoparaffins and alkylcyclopentane light hydrocarbon series, thiofluorene and desalpane; lean bicyclic sesquiterpenes, especially lignocerone; [Sigma] alkylcyclohexane / Higher values of paraffin, heavier δD value and lighter δ ~ (13) C value, the former average -29.8 ‰; the latter average -119.7 ‰. In continental brackish water, the semi-saline lake condensate is rich in sulfur-containing compounds, especially thiofluorene; the content of Σ-alkylcyclohexane / Σ-n-alkanes is slightly less than that of marine condensate; ~ (13) The C value and the δD value, the average values were -25.5 ‰ and -121.2 ‰, respectively. The whole hydrocarbon chromatogram inherits the weak parity. Brackish water, freshwater lake phase condensate is relatively rich in bicyclic sesquiterpenes, especially cone of methane and cone full of alkyl and fluorene. Marsh phase condensate is rich in toluene, methylcyclohexane (light hydrocarbons), bicyclic sesquiterpenes and fluorene; but also detected by oil leaf oil and other terrestrial compounds; Σ alkyl cyclohexane / Σ N-paraffin is smaller, with pristane advantage; δ ~ (13) C value heavier, with an average of -26.5 ‰.
