Overview of In-Situ Gelation Behavior of Gel Systems in Porous Media

Cross-linked polymer gel has been widely applied in profile control and water plugging due to its effective cost, wide suitability, excellent performance, flexible gelation time. Previous research mainly focused on the bottle tests, reaction kinetics, rheological properties of gels, but works literature about situ gelations placement porous media are relatively few. The study in-situ behavior systems is summarized this paper, tendency proposed. important practical questions, including accurate lateral distance placement, variation properties, injection pressure process injection, should be resolved by laboratory numerical enhance treatment success rate.
