Изобретение относится к разработке нефтяных месторождений с трудноизвлекаемыми запасами нефти. Цель - повышение эффективности способа за счет увеличения охвата неоднородных и слабопроницаемых пластов воздействием при одновременном уменьшении материальных затрат и упрощении технологии. Для этого при одновременно раздельной закачке воды и газа в газовую линию закачивают предварительно полученную на устье скважины стабильную газоводяную пену, полученную эжектированием путем подачи газа под давлением 0,1 - 0,5 МПа и воды 10,0 - 20,0 МПа. Закачку ее ведут до обрабатываемого интервала перфорации, где смешивают пену и воду высоконапорным струйным инжектором. Полученную водогазовую смесь закачивают в пласт под воздействием упругих колебаний, например, с помощью гидродинамического генератора. Способ исключает дополнительные капиталовложения при внедрении в промысловых условиях, так как не требует специального оборудования.The invention relates to the development of oil fields with hard to recover oil reserves. The goal is to increase the efficiency of the method by increasing the coverage of inhomogeneous and low-permeable formations by exposure while reducing material costs and simplifying the technology. For this, while simultaneously pumping water and gas into the gas line, stable gas-water foam previously obtained at the wellhead, obtained by ejection by supplying gas under a pressure of 0.1-0.5 MPa and water 10.0-20.0 MPa, is injected into the gas line. Its injection is carried out to the processed perforation interval, where foam and water are mixed by a high-pressure jet injector. The resulting water-gas mixture is pumped into the reservoir under the influence of elastic waves, for example, using a hydrodynamic generator. The method eliminates additional investment when implemented in field conditions, as it does not require special equipment.
