Способ разработки нефтяной залежи, включающий отбор нефти через добывающие скважины и закачку рабочего агента и дегазированной нефти через нагнетательные скважины, отличающийся тем, что используют дегазированную нефть с вязкостью больше вязкости нефти в разрабатываемой залежи, дегазированную нефть нагревают до температуры, при которой ее вязкость близка к вязкости воды в пластовых условиях, и закачивают двумя порциями при давлении закачки первой порции меньшем на 15-25% давления закачки рабочего агента между порциями закачки дегазированной нефти, при этом объем закачки второй порции дегазированной нефти составляет 30-70% объема закачки первой порции, а объем закачки воды составляет 15-30% общего объема закачки дегазированной нефти.A method for developing an oil reservoir, including the selection of oil through production wells and pumping a working agent and degassed oil through injection wells, characterized in that degassed oil with a viscosity higher than the viscosity of the oil in the reservoir being developed is used, the degassed oil is heated to a temperature at which its viscosity is close to viscosity of water under reservoir conditions, and is pumped in two portions at a first portion lower injection pressure of 15–25% lower than the working agent injection pressure between the degasser injection portions constant oil volume while pumping the second portion of the degassed oil is 30-70% of the injection of the first portion, and the amount of injection water is 15-30% of the total pumping degassed petroleum.
