| Abstract: | 1 INTRODUCTION In recent years, colloidal dispersion gel(CDG) have been attracting more and more in the field of enhanced oil recovery on account of the cost-effectiveness and high efficiency of blocking formation. Compared with bulk gel(BG) , CDG exhibits lower polymer concentration, undefined shape and selective blocking formation characteristics1-5]. The characteristics of CDG and BG are related to structure. In the bulk gel a continuous network of polymer molecules is formed predominant through intermolecular cross-linkages. |
