Abstract: According to the actual development features of Daqing Oilfield, the ideal model was established. With the help of the numerical simulating method, the influence laws of 12 factors to the enhanced degree of the oil re-covery were analyzed, in detail, the factors are classified into the contents and slug sizes for the ASP flooding with main slug, deputy slug, pre-slug and sub-slug, the recovery formula was obtained by multivariate nonlinear mixed regression method, and moreover with the help of function optimal value theory, the maximal recovery factor and corresponding values of each slug size were achieved. The achievements show that there are the nonlinear relation-ships between the 12 slug factors and recovery factors, therefore the secondary multivariate nonlinear regression for-mula can be presented, and then by means of function optimal value method, the maximum recovery factor is up to 66. 525%. A set of the optimizing method was established for the slug sizes and chemical agent formula of the pre slug, main slug, vice slug and protecting slug. These achievements possess important significance for the applica-tion study of the numerical simulation of the ASP flooding
