Synthesis of Polyacrylamide Gels for Restricting the Water Inflow in Development of Oil Fields

Thermally stable hydrogels resistant to highly mineralized stratal water were synthesized from the nonionogenic polyacrylamide, paraform, resorcinol, sulfosalycilic acid, and Atren Fibre structuring additive. It was shown that the hydrogels are promising for development of gel screens in the borehole zone of oil-producing wells to restrict the water inflow and raise the oil recovery factor.
