FIELD: oil and gas producing industry, particularly, methods of treatment and demudding of bottomhole zones. SUBSTANCE: method consists in injection of solution of sodium naphthenate through tubing into flow string with its subsequent forcing into formation. Sodium naphthenate solution in service or formation water is prepared in ratio of 1:(0.5- 3) and injected into formation in amount of 0.4-5 cu.m per meter of formation thickness. Well is left to stand under pressure for 6-24 h. EFFECT: increased oil production rate.
