【Abstract】 In this paper an investigation is conducted of the characteristics of polymer 935L(a partially hydrolyzed polyacrylamide),its solution properties,and adsorption onto and re- tention in formation rock from solution.The crosslinking reaction between 935L and alumin- Jam citrate in aqueous solution is discussed in relation to using this gelling system for controlling water-intake profile.The flowing core test in an alternate injection schedule is performed and shows that this schedule can be applicable to oilfield tests,更多还原
