FIELD: oil industry; collecting, preparing and storing oil in the field and in industries having to do with production, storage and distribution of oil and oil products. SUBSTANCE: to cut down losses of hydrocarbons in form of vapor phase formed at pumping oil and oil products in out of reservoir, prior to injection of oil, reservoir is completely filled with water, and operations on injection and pumping out of oil and oil products are carried out synchronously with taking out and injection of water into reservoir. Water, at injection of oil and oil products, is forced out into surge tank, and when oil or oil products are pumped out of main reservoir, water from surge tank is pumped into oil reservoir. EFFECT: enlarged operating capabilities. 1 dwg
