Способ относится к нефтяной промышленности и может быть использован при разработке залежей нефти высокой и повышенной вязкости. Цель изобретения - увеличение нефтеотдачи залежи. Для этого в предлагаемом способе разработки нефтяной залежи, включающем закачку через нагнетательные скважины теплоносителя, раствора полимера и ненагретой воды и отбор нефти через добывающие скважины, закачку теплоносителя и раствора полимера производят чередующимися оторочками, причем оторочку теплоносителя закачивают перед оторочкой раствора полимера, а объемы оторочек теплоносителя Vт и раствора полимера Vп определяют из новых аналитических соотношений.The method relates to the oil industry and can be used in the development of high and high viscosity oil deposits. The purpose of the invention is to increase oil recovery deposits. To do this, in the proposed method of developing an oil reservoir, which includes injection of coolant, polymer solution and unheated water through injection wells, and oil extraction through production wells, heat carrier and polymer solution injection, alternate rims are produced, and the rim of the heat carrier is pumped before the rim of the polymer solution, and the volume of the handpieces are extracted, and the volume of the heat source is pumped in front of the rim of the polymer solution, and the volume of the handpieces, and the part of the heat carrier is pumped in front of the bead of the polymer solution, and volumes of the handhelds, and the volumes of the handpieces, and the part of the coolant is pumped in front of the bead of the polymer solution, and volumes of the handpieces, and the volumes of the handguns are pumped in front of the hemline of the polymer solution, and the volume of the handpieces, and the volume of the heat source are pumped in front of the dismount of the polymer solution, and the volume of the handpieces, and the volume of the helix will be pumped in front of the hem V t and polymer solution V p determined from the new analytical ratios.
