| Abstract: | The aqueous selling profile modificator SA_2-GD is prepared from polyacrylamide and redox crosslinker thiourea sodium bichromate at surface. The effects of every formulation variables and other factors on the properties of the gelling and gelled solution are investigated and the optimal composition is formulated. This chemical agent shows long and adjustible gelation time, the gel formed has high strength and strong plugging capacity. The field tests on 13 injection wells are all successful ; the average effective time of a remidial operation on a well accounts 150 days; 18 producing wells of 27 in the well nets are enhanced in oil output over 107 days. |
