Abstract


ASP flooding is one of main ways for oilfields to enhance oil recovery, but it needs to further research which slug parameters of ASP flooding are important factors influencing oil recovery. Taking a pilot zone as example, by designing scheme with orthogonal design method to conduct numerical analog calculation, analyzing data with grey correlation and multiple regression, it concluded that dosage of main slug, concentration of polymer, concentration of surface active agent and auxiliary slug are main factors influencing oil recovery; combining these factors to predict water containing rule can obtain water containing rule prediction formula with higher accuracy to meet requirements on site.


Keywords
