摘要 天然气数据相对比较简单,只有组份和同位素两类,但是这些数据却包含了天然气从烃源岩生成到聚集成藏之间所经历的生成、排驱、运移、聚集和成藏后的改造等过程,所有这些过程都可以导致天然气组份和同位素组成发生变化.本文在大量国内外有关天然气数据和研究成果的基础上,以塔里木盆地天然气研究为实例,分析控制和影响天然气组份和同位素的主要因素,认为天然气组份和同位素主要受源岩的类型和成熟度(即所谓的"源控")、成藏过程和次生作用控制.通过对天然气组份和同位素组成控制因素的认识,必将加深对天然气数据的理解,从而使我们在天然气研究和勘探中不仅要认识源岩和成熟度对天然气数据的控制,而且要认识成藏过程和次生作用对天然气数据的控制.

Abstract: The data from natural gas are relatively simple, including two types only, namely, components and isotopes of gas. But these data must have contained many processes for gas from source rocks to reservoirs, such as generating, expulsing, migrating, accumulating and alteration, which may affect the components and isotopes of natural gas. Based on a lot of gas data and many studies, the main factors for controlling geochemical characteristics of natural gas were discussed in the paper, taking natural gas in the Tarim Basin as an example. The data showed that the components and isotopes were mainly controlled by source type and maturity (being called "source controlling" by some reseachers), filling process and secondary action after accumulating. The recognition of controlling factors on the components and isotopes of natural gas might make us to deepen understandings the data of natural gas. In addition to source type and maturity (the source controlling), filling process and secondary action after accumulating must have been important factors for geochemical characteristics, which would be helpful to study and exploration of natural gas.
Key wordsNatural gas data   Source type and maturity   Filling process   Diffusion
