FIELD: oil production, particularly to stimulate oil production from oil reservoir and to reduce water content in extracted product.
SUBSTANCE: method involves performing periodic injection of composite mineralized water system in reservoir through injection well between plug injections. The mineralized water system includes latex, nonionogenic surfactant and water. The system may additionally have salting inhibitor, namely nitriletrimethylphosphonic acid. Above components are taken in the following amounts (% by weight): latex - 0.6-5.0, nonionogenic surfactant - 0.03-1.0, nitriletrimethylphosphonic acid - 0.05-0.5, remainder is water.
EFFECT: increased efficiency of oil field development control, possibility to maintain or to increase injection well injectivity and to control settled sediment mass over reservoir area, increased conformance and oil recovery and decreased water content in produced oil.
