| Abstract: | Deep profile - control flooding technology with weak gel can make full use of the advantages of crosslinked polymer. The weak gel was prepared using polyacrylamide as primary component and aluminum citrate as organic crosslinking agent. The formula of the weak gel with high viscosity and appropriate gelling time was obtained by experiments as follows： molar ratio of aluminum chloride （crosslinked body） to sodium citrate （ligand） 1 ： 1 in the organic crosslinker, 8% - 12% （w） of the organic crosslinker, 0.08% - 0. 17% （ w ） of polyacrylamide. |

| Keywords: | weak gel profile control crosslinker gelling property |
