储层建模研究进展及发展趋势

Research progress and trend of reservoir modelling

油气田开发的后期进入高含水阶段,为了更加经济准确地进行油气开发,有必要采用储层地质建模的方法对老油气田进行储层研究。详细阐述了国内外储层地质建模的发展史,对储层地质建模的方法进行了细致的分类及论述。方法分类包括确定性建模方法和随机性建模方法。每一种建模方法又有多种子方法。提出了目前储层地质建模研究尚未很好解决的一些问题,如建模的对象局限于常规的碎屑岩储层。虽然有学者对火成岩、裂缝碳酸盐岩进行了相关的探究工作,但目前对非常规储层涉及较少,储层建模的精度也有待提高。

Upon entering later high water cut stage, oil and gas development, for more economical and accurate oil and gas exploita- tion, needs to adopt the reservoir geological modelling method to study previous oil and gas reservoir. This paper detailed the domestic and foreign history and classification of the development of reservoir geological modelling method. The classification includes determinis- tic and stochastic modelling method, each method containing many sub-methods. The paper also presented some of the problems that have not been solved well so far in the study of reservoir geology modelling, such as the modelling object limited to conventional clastic rock reservoir. Although some scholars have studied the igneous rock and fractured carbonate rock, the unconventional reservoir is still lack of intensive study and the precision of reservoir modelling needs to be improved. Moreover, the application of reservoir modelling method should be more accurate.
