Abstract
FIELD: oil-and-gas industry, particularly, methods for development of oil deposits. SUBSTANCE: method includes successive injection into formation through injection wells of fringes of alkali solutions and mineralized formation water of the given pool separated by a fringe of fresh water. EFFECT: higher efficiency of the method due to alignment of flood front.

Изобретение относится к нефтегазодобывающей промышленности, в частности, к способам разработки нефтяных месторождений. Цель изобретения - повышение эффективности способа разработки неоднородного нефтяного пласта за счет выравнивания фронта заводнения. При разработке неоднородного пласта производят последовательную закачку в пласт через нагнетательные скважины оторочек раствора щелочи и минерализованной пластовой воды данной залежи, разделенных оторочкой пресной воды.The invention relates to the oil and gas industry, in particular, to methods for developing oil fields. The purpose of the invention is to increase the efficiency of the method for developing a heterogeneous oil reservoir by leveling the waterflooding front. When developing a heterogeneous formation, sequential injection into the formation through injection wells of the rims of alkali solution and mineralized formation water of this reservoir, separated by a rim of fresh water, is performed.
