Abstract
The zones having poor reservoir properties remain unrecovered in flooding of the carbonate producing formations characterized by presente of many fractures in combination with low-permeability matrix. To solve the problem the technology for the treatment of the oil- and water-saturated reservoirs based on an increase of filtration resistance of the high-permeability watered reservoir zones using the polymer-dispersion systems (PDS) consisting of water-soluble polymers, dispersion rock particles and modifying additives has been developed.
