Abstract

Изобретение относится к способу регулирования проницаемости нефтяной скважины, имеющей зону поглощения, включающему следующие стадии: I) приготовление полимеризуемой двухкомпонентной системы, содержащей по меньшей мере флюид A, содержащий (a-i) по меньшей мере олефиноненасыщенное первое полимеризуемое соединение; (a-ii) необязательно по меньшей мере один инициатор радикальной полимеризации IA для полимеризации указанного полимеризуемого соединения, указанный инициатор IA активируется термическим образом или в присутствии ускоряющего соединения; флюид B, содержащий активатор радикальной полимеризации, указанный активатор выбран из (b-i) инициатора радикальной полимеризации IB для полимеризации указанного полимеризуемого соединения, указанный инициатор IB имеет температуру активации, равную или ниже, чем температура указанной зоны поглощения, (b-ii) ускорителя указанного инициатора IA; II) инжектирование одного из указанного флюида A и указанного флюида B в затрубное пространство указанной скважины до достижения указанной зоны поглощения; III) инжектирование оставшегося из указанного флюида A и указанного флюида B в трубчатый элемент, образованный колонной полых буровых штанг, до тех пор, пока он не приходит в контакт с флюидом, инжектированным через указанное затрубное пространство, чтобы сформировать блокирующий полимер в указанной зоне поглощения.
