Abstract

Abstract: Injectivity reduction is an important factor to restrict recovery increase by gasalternatingwater flooding.Based on dimensionless scaling rule by inspectional analysis，the plot displaying the relationship between dimensionless injectivity and heterogenity is established in threephases relative permeability and capillary pressure hysteresis model by compositional simulation.Meanwhile，the optimal ratio of injected water and gas is obtained.The results show that displacement effect by increasing enrichment of injection gas is batter than by increasing injection velocity in a certain reservoir system，injectivivty decline trend is more obvious if water/injection gas ratio is higher.The optimal injection is that WGR is 2 for low viscous and gravity force ratio and WGR 1 for low viscous and gravity force ratio.It suggests that characteristic of formation and injecting fluid is involved in discussing injecting optimization

Key words: gasalternatingwater flooding, dimensionless injectivity, inspectional analysis, water and gas ratio, viscous and gravity force ratio
