流动单元是油气储集的最小宏观地质单元,它综合反映了储层的岩性、物性及微观孔喉特征。储层流动单元研究是当今国内外储层研究的热点,其目的是更精细地刻画储层非均质性,指导油气勘探开发。文中从流动单元的概念出发,简要阐述了国内外学者对流动单元的划分和研究方法,以期能更有效地深入开展储层流动单元研究。 The flow cell is the smallest macro-geological unit of oil and gas reservoir, which comprehensively reflects the lithology, physical properties and microscopic pore-throat characteristics of the reservoir. The study of reservoir flow units is a hot research topic in reservoir research both at home and abroad. Its purpose is to describe the reservoir heterogeneity finerly and guide the exploration and development of oil and gas. In this paper, starting from the concept of mobile units, this paper briefly describes the division and research methods of mobile units at home and abroad, with a view to the study of reservoir flow units more effectively.
