微观剩余油仿真研究进展

Research progress on simulation of microscopic remaining oil

为进一步挖潜地下石油资源,许多学者进行了微观剩余油仿真研究。结合给出的微观剩余油仿真定义的分析,阐述了其国内外研究现状,认为现阶段我国微观剩余油仿真研究存在以下不足:实验环境与地下真实环境相差较大、忽略岩石的润湿性、仿真基本上在二维空间开展及没有准确表征储集层微观孔隙结构。之后对已有的微观剩余油仿真研究工作进行了总结,并对我国未来的微观剩余油仿真研究提出了6点展望:提高物理实验质量、利用分形几何理论、CT技术、结合油田地质特征、构建三维微观孔隙结构及建立完整理论体系。微观剩余油仿真对揭示地下剩余油的分布规律具有重要意义,因此综述各家之言,以期为将来微观剩余油仿真研究提供参考。

Many scholars have carried out the research on the simulation of microscopic remaining oil in order to develop the underground petroleum resources further. Firstly, this paper gave the simulation of microscopic remaining oil definition and elaborated the research situation home and abroad. Secondly, pointed out the existing deficiencies of the current simulation of microscopic remaining oil on four aspects： the great difference between the experimental environment and the real underground environment, the ignorance on the wettability of the rock, the research only completed in the two-dimensional space and the inaccurate representation of the reservoir microscopic pore structure. Thirdly, summarized the studies on the simulation of microscopic remaining oil in our country, and put forward six suggestions on the future development for the simulation of microscopic remaining oil, which are to improve the physical experiment, use the fractal geometry theory and CT technology, combine with the actual geologic features and establish the complete theoretical system. The simulation of microscopic remaining oil is of great significance for the revelation of the microscopic remaining oil distribution, therefore various viewpoints about the simulation of microscopic remaining oil were reviewed in order to provide reference for the future research.
