Quantitative reservoir classification and evaluation based on reservoir microscopic characteristics

In view of the remaining oil recovery situation and needs development tertiary technology, using mercury intrusion data, through statistical analysis relationship between microscopic pore structure parameters permeability, it is clear that there a good correlation permeability various parameters. It believed reservoir can comprehensively quantitatively characterize complexity reservoir. The higher weaker heterogeneity better quality. And according to characteristics reservoir, divided into Type I II III IV V which realizes quantitative classification evaluation complex reservoirs, best for reservoirs. deepening understanding strata has laid foundation selection injectors.
