摘　　要：目前在天然气研究中,对湿气和凝析油气来说,主要是以其中油的C4—C7烃类指纹和天然气的碳同位素来揭示天然气的成因,但在很多情况下,天然气和油是不同源的,并且在高—过成熟天然气中可用的有效信息量少。针对这一现状,自制了天然气C3—C8烃浓缩器,在现场井口直接采集天然气浓缩样品,并建立了天然气C3—C8烃浓缩实验新方法。该方法能有效地分析出天然气中的C3—C8烃类,为解决天然气组分少而气源对比困难等问题提供了新思路和新方法。So far study on natural gas origin focuses on oil C4-C7 hydrocarbons and natural gas carbon isotope in wet gas reservoir and condensate reservoir. Under more circumstances, it is different from source rock between natural gas and oil; another is that the components of natural gas is rather simple, useful information is a small quantity. So we research of concentrate instrument of natural gas C3- C8 hydrocarbons. It can collect natural gas sample in the well site, in the same time we establish new method that can effective analyze natural gas C3- C8 hydrocarbons. It can provide scientific basis for the components simple of natural gas, the gas-source Correlation difficulty of a new train of though and method.
