FIELD: oil and gas production.
SUBSTANCE: invention can be used for treatment of bottomhole zone of non-uniform oil reservoirs including those operated at bottomhole pressure below pressure of saturation under conditions of delivery and accumulation of gas in bottomhole zone and also at treatment of reservoirs producing high viscous oil. Composition for treatment of the bottomhole zone of oil reservoirs includes, wt %: anion active surface active substance SAS or composition of anion active SAS 0.002-0.03, nano particles of light non-ferrous metal of dimension 50-200 nm 0.0005-0.0015, water - the rest.
EFFECT: increased efficiency of composition for treatment of bottomhole zone due to reduced surface tension of composition at boundary with oil at maintaining non-Newton properties.
