Abstract

Способ обработки подземного пласта, имеющего по меньшей мере один первичный нефтеносный слой и по меньшей мере один первичный водоносный слой. Способ содержит операции, при которых в пласт закачивают перекрывающий воду гель для избирательной обработки водоносных слоев. После этого в пласт закачивают вязкоупругую текучую среду, которая расщепляется углеводородами, тем самым оставаясь и увеличивая свою вязкость в первую очередь в водоносных слоях. Далее закачивают реактивную текучую среду, например кислоту. Реактивная текучая среда воздействует в первую очередь на нефтеносные слои, поскольку вязкоупругая текучая среда и перекрывающий воду гель, по существу, предотвращают попадание реактивной текучей среды в водоносные слои.Международная заявка была опубликована вместе с отчетом о международном поиске.
