Application of cation-active poly-electrolites for oil recovery increase

Presented are results of experimental studies on possible application of ca tion-active poly-electrolites VPK-402 and methacides for oil recovery incre ase technologies. It is shown, that methacide addition to polyacrylamide so lution significantly reduces biopolymer distruction, resulting in the incre ase of efficiency of development of pools with increased viscosity and high viscous oils. Developed ore a solution, eliminating swelling of formation clay components, and composition, designed for treatment of producers with the purpose of water influx isolation, as well as for treatment of injector s with the purpose of controlling filtration flows inside formation.
