The article analyzes the viscoelastic compositions breakthrough in the process of polymer flooding pilot testing in the conditions of a complex terrigenous reservoir of the Zaburunye deposit. It was found that a significant increase in the polymers concentration in producing wells is due to the high reserves’ depletion in the sites. It is shown that significant injection volumes, including polymers, as well as the new wells involvement into testing as part of polymer flooding experiment expansion are not environmentally justified, which is due to the high-filtering channels appearance, which are the main cause for physical destruction of polymer chains. To control this phenomenon, a variant of high-viscosity fringes pumping is proposed.
