Currently, the most powerful and energy-intensive method of influence on the productive strata is water flooding. Due to certain economic factors, dictated by saving of capital costs on drilling of injection wells, a number of injection wells is much smaller than the development wells number. It is natural, that for full-value compensation of volumes of produced liquid from the development wells, taking into account losses, it is necessary to pump large volumes of water which can reach 1000-2500 m3 per day into a less number of injectors. Such conditions of water flooding lead to a need to create high pressure at the bottomhole and repression in the injection wells, which contributes the unfocused hydraulic fracturing. The results of the scientific research performed by S. I Grachev and A. S. Trofimov in a number of known fields using the method of tracer studying have shown that in all fields, where such studies were conducted, there observed the so-called channels with ultra-low hydraulic resistance, or with ultra-high conductivity/ permeability.
