Abstract

В заявке описан способ оценки изменения смачиваемости пористого и проницаемого нефтегазоносного пласта в области, расположенной вокруг проходящей сквозь этот пласт скважины, включающий: (i) размещение скважинного прибора ЯМР-каротажа в скважине на глубине, соответствующей интервалу нефтегазоносного пласта; (ii) измерение времени релаксации для флюида, находящегося внутри нефтегазоносного пласта; (iii) опционно, извлечение скважинного прибора ЯМР-каротажа из скважины; (iv) закачку флюида в нефтегазоносный пласт в рамках процесса вторичного или третичного извлечения, или процесса с использованием методов повышения нефтеотдачи (МПНО-процесса), в течение такого периода времени, за который известный объем порового пространства или частичный объем порового пространства будет заполнен флюидом; (v) опционно, закрытие скважины на период времени; (vi) возврат скважины в эксплуатацию и извлечение закачанных флюидов с возможным регенерированием последних; (vii) повторное размещение, в случае необходимости и после извлечения закачанных флюидов, скважинного прибора ЯМР-каротажа в скважине, по существу, на той же глубине, что и раньше; (viii) измерение времени релаксации для флюида, находящегося внутри нефтегазоносного пласта; (ix) опционно, повторное выполнение стадий (iv)-(viii) с извлекаемым флюидом, отличным от флюида, первоначально использованного на стадии (iv).
