摘要：

油气运聚解析是石油地质学研究的基础命题,而复杂油气运聚解析则是研究难点和热点。以准噶尔盆地腹部陆西地区为例,提出了解析复杂油气运聚的一种新方法,即油气运聚类型研究。这种方法提出了新的研究思路。主要有两方面作用：一是在勘探发现油气显示后,通过分析油气运聚类型,进而评价成藏潜力,为试油提供依据；二是在试油之后,对成功和失利的井分别分析原因,解析二者在油气运聚类型和过程上的差异,从而为油气勘探部署和评价提供参考。以陆西地区为例的应用效果良好,尽管诸多参考标准并不一定完全适用于其他地区,但研究思路、方法可供借鉴。

Abstract:

The study of petroleum migration and accumulation is a fundamental scientific issue in petroleum geological researches. To investigate complex petroleum migration and accumulation is a hot and difficult topic in the research. In this paper, we have proposed a new method for investigating the complex petroleum migration and accumulation, i.e., the petroleum migration and accumulation type, based on a case study in the Luxi Area of the central Junggar Basin. The applications of the method are twofold. First, after the discovery of hydrocarbon shows in exploration, the analysis of the petroleum migration and accumulation type could provide basic information for assessing petroleum accumulation potential and oil well testing. Second, the difference of petroleum migration and accumulation type/process between successful and failure wells should be studied after the oil well testing, which could provide basic information for shaping the strategy of  petroleum exploration and assessment. The above method had a successful application in the case study of the Luxi Area and showed promising prospects. Thus, this method can be popularized and applied in other areas, though the distinguishing criteria suggested on the basis of the Luxi Area may not be used arbitrarily in the other areas.

Key words:  petroleum migration and accumulation, petroleum reservoir formation, hydrocarbon show, organicinorganic geochemistry, Junggar Basin, Luxi Area
