Variation of Key Parameters of Reservoir Characteristics by ASP Flooding

Abstract

Abstract: The important prerequisite ensuring the application effect of ASP flooding is determined by the extent of the impact of characteristic parameters variations of reservoir. The variations of the characteristic parameters such as wettability, sensitivity, porosity, permeability of cores, which were drilled before and after ASP flooding in Daqing Oilfield, are analyzed systematically by core-flooding experiments and AFM. The measurement results of relative permeability show that the wettability of reservoir core will change from oil wet to water wet after ASP flooding. The sensitivity experiments indicate that ASP flooding will lead to different influence on types of sensitivity, mainly including the increase of water sensitivity, but the decrease of sensitivity of velocity,acid and alkali. Statistical analysis of the reservoir porosity and permeability shows that both the absolute value of porosity and permeability of core increase and they relatewell with each other. The observations of AFM for microscopic pore structure of core further validate the understanding of the porosity and permeability improvement.

Key words: ASP flooding, wettability, sensitivity, porosity, permeability
