FIELD: oil and gas industry.
SUBSTANCE: development method of oil formations that are non-homogenous as to permeability involves pumping of a polymer and a suspension of filler. Polysaccharide reagent TsPK is used as polymer, wood or dolomite powder or bentonite clay powder is used as filler; the above polymer and filler is pumped in the form of water suspension or in series in the form of water suspension of polysaccharide reagent TsPK and water suspensions of the above filler at their volumetric ratio of 1-5:1 till specific water-intake capacity of a well is reduced by 10-60% at the following component ratio, wt %: polysaccharide reagent TsPK 0.05-3.0, the above filler 0.01-10.0, and fresh or mineralised water is the rest.
EFFECT: improving development efficiency of oil formations that are non-homogeneous as to permeability; enlarging technological capabilities of the method.
