OIL DEPOSIT DEVELOPMENT METHOD Russian patent published in 2010 - IPC E21B43/243 

FIELD: oil and gas industry.

SUBSTANCE: method involves oil withdrawal through production wells, ignition of oil formation and pumping of air and working agent to pressure wells. According to invention, after 45-50% of removable stocks to pressure wells as working medium is removed, hot water with temperature of not less than 60°C, density of 1.000-1.005 g/cm³ and viscosity exceeding the viscosity of pumped air is pumped. At that, hot water is pumped through pressure well with small formation pressure in the centre of the chosen section of developed deposit, production wells with water content of 99% close and provide heat transfer from zone of high temperatures of deposit to zones of its low temperatures by covering the areas exceeding the sizes of the chosen section.

EFFECT: increasing oil recovery efficiency of deposit owing to involvement in development of zones of formation layer with non-used stocks.
