含油气系统研究存在的问题和发展趋势

含油气系统概念自上世纪六七十年代提出以来 ,已经广泛应用于石油地质勘探领域 ,并逐步实现石油地质理论和系统思路的有机结合。目前国内外含油气系统的研究都是基于Perrodon与Dow于 1 994年综合得到的含油气系统概念 ,并结合已有的地质资料和技术手段 ,将含油气系统的四个基本要素和两个地质作用进行较为系统的分析 ,从而预测有利的远景油气区带。但是目前在“含油气系统”名词的翻译、含油气系统的划分原则和方法、含油气系统的具体研究方法 ,尤其是如何在地质条件和成藏模式复杂的我国陆相含油气盆地进行含油气系统分析等方面 ,至今仍未得到很好的解决。综合国内外研究进展 ,认为 :含油气系统的研究逐渐趋向于将静态的地质要素和动态的生成、运移、聚集和保存过程统一起来进行系统分析研究并达到定性和半定量化、定量化研究相结合 ,使含油气系统的新思路和新方法得到不断的丰富和发展。

Problems In Petroleum System's Research and Its Developing Trend

The concept of petroleum system was put forward from 60s to 70s, and has been applied to petroleum geology exploration field widely, with gradual organic combination between the theories of petroleum geology and system thoughts. Up to now the research of petroleum system, home and abroad, bases on the concept gained synthetically by Perrodon and Dow in 1994. Four basic factors and two geological processes are systematically analyzed to forecast advantageous perspective regions, with geology materials in hand, techniques and means. However, there are some aspects not to be tackled, just as translation of the noun "petroleum system", principles and methods of petroleum system's division, idiographic research methods, especially how to study petroleum system in continental facies basin in China, with complex geology condition and pool's forming mode. Synthesizing petroleum system's research actuality for home and abroad,It is considered that the research of petroleum system is tending to do the systematic research on unification of static geology factors and dynamic forming, migration, accumulation, and keeping processes so as to combine qualitative analysis, half-quantitative analysis with quantitative analysis, as a result,new thought and new method of petroleum system can be enriched and developed.
