Description
При существующих способах кислотной обработки нефт ных пластов зачастуЕО дл получени удовлетворительного эффекта необходимо нагнетать в пласт весьма большие объемы кислоты.With the existing methods of acid treatment of oil reservoirs, it is often necessary to obtain very large volumes of acid in order to obtain a satisfactory effect.
В цел х экономии кислоты, а также возможности обработки отдаленных от забо частей пласта предлагаетс поданную на забой обрабатываемой скважины сол ную кислоту нагнетать в пласт посредством нефт ного газа или воздуха, подаваемых с поверхности.In order to save acid, as well as the ability to process parts of the formation distant from the bottom of the formation, it is proposed to pump hydrochloric acid into the formation by means of oil gas or air supplied from the surface.
Под давлением нагнетаемого газа или воздуха будет происходить продвижение кислоты по нласту, благодар чему улучшитс ее использование.Under the pressure of the injected gas or air, the acid will advance along the nlast, thereby improving its use.
Дл большей эффективности процесс может производитьс путем чередующеЙ1СЯ закачки в пласт кислоты и газа.For greater efficiency, the process can be carried out by alternating injection of acid and gas into the formation.
По окончании процесса обработки газ выпускаетс , нефть притекает к забою по широкой, обработанной кислотой, дренажной площади .At the end of the treatment process, the gas is released, the oil flows to the bottom of a wide, acid-treated drainage area.
Предмет изобретени Subject invention
Способ обработки пластов нефт ных скважин, отличающийс тем, что поданную на забой обрабатываемой скважины сол ную кислоту нагнетают в пласт посредством нефт ного газа или воздуха, закачиваемых с поверхности.A method of treating reservoirs of oil wells, characterized in that the hydrochloric acid supplied to the bottom of the well being treated is injected into the formation by means of oil gas or air pumped from the surface.
