Abstract
Способы обработки пласта, вскрытого стволом скважины, который улучшает регулирование фильтруемости в процессе обработки. В некоторых аспектах, обработки включают приготовление водной жидкости, включающей один или более инертных к воде полимеров и необязательный загуститель, закачивание водной жидкости в ствол скважины при давлении, равном или большем, чем давление гидроразрыва пласта, и после этого закачивание в ствол скважины жидкости, содержащей проппант, при давлении, равном или большем, чем давление гидроразрыва пласта. Инертный к воде полимер может быть полимером, таким как эмульсионный полимер или латексный полимер. Такие способы изобретения используют жидкость, которая может иметь нормализованный коэффициент фильтруемости (Cw/sqrt(K)), равный или меньший чем 0,0022, 0,0014 или 0,0010. Традиционная снижающая фильтрацию добавка может использоваться или может не использоваться в сочетании с жидкостью для обработки приствольной зоны и/или жидкостью, содержащей проппант. Инертный к воде полимер может проникать или может практически не проникать в поры пласта. В другом аспекте, способы для снижения повреждения вмещающей породы пласта в процессе операции обработки включают приготовление водного раствора для обработки приствольной зоны, образованного по меньшей мере одним инертным к воде полимером, и закачивание жидкости при давлении, равном или большем, чем давление гидроразрыва пласта.
