Способ термошахтного извлечения высоковязкой нефти из пласта относится к добыче нефти или газа и может быть использован для дополнительного извлечения нефти или газа с использованием упругого миграционного геоэффекта и кавитации во флюидосодержащих породах на глубинах до 15 км и более. Цель изобретения - повышение нефтеотдачи и снижение энергоемкости. Сущность способа заключается в том, что виброисточники размещают в вертикальных и наклонных нагнетательных скважинах, возбуждают упругие колебания в выбранном диапазоне частот в совокупности с нагнетанием в породы пласта разупрочняющих растворов и производят вибровоздействия в широком диапазоне частот в течение времени, при котором прочность пород пласта на разрыв снизится на 10 - 40%, после чего переходят на частоту колебаний, равную частоте собственных колебаний пласта в совокупности с нагнетанием в пласт теплоносителя; вибровоздействия осуществляют в течение времени, при котором достигают положительного эффекта, состоящего в том, что нефтеотдача повышается на 10 - 40% по сравнению с первоначальной. Это позволяет снизить температуру теплоносителя на 30 - 40% и повысить извлечение высоковязкой нефти на 10 - 60% по сравнению с другими способами. Ожидаемый экономический эффект от внедрения предлагаемого способа - 16 - 19 млн.руб/год.The method of thermo-mining extraction of high-viscosity oil from a reservoir refers to the extraction of oil or gas and can be used for additional extraction of oil or gas using elastic migration geoeffect and cavitation in fluid-containing rocks at depths of up to 15 km or more. The purpose of the invention is to increase oil recovery and reduce energy intensity. The essence of the method lies in the fact that the vibration sources are placed in vertical and inclined injection wells, excite elastic oscillations in the selected frequency range in conjunction with injection of softening solutions into the formation rocks and produce vibration effects in a wide frequency range during the time at which the formation rocks tens decrease by 10 - 40%, after which they switch to the oscillation frequency equal to the frequency of natural oscillations of the formation in combination with the injection into the reservoir of the coolant; vibroexposure is carried out during the time at which a positive effect is achieved, consisting in the fact that the oil recovery increases by 10-40% in comparison with the initial one. This allows you to reduce the temperature of the coolant by 30 - 40% and increase the extraction of high-viscosity oil by 10 - 60% compared with other methods. The expected economic effect from the introduction of the proposed method is 16 - 19 million rubles / year.
