Abstract

Описаны текучая среда для доставки нефтепромыслового реагента, содержащая смесь базовой текучей среды и микрокапсул (1, 10, 11, 13, 14, 15), имеющих нефтепромысловый реагент, содержащийся внутри микрокапсулы. Химические группы на внешней поверхности микрокапсул взаимодействуют с базовой текучей средой и способствуют диспергируемости микрокапсул в базовой текучей среде. Химические группы на внешней поверхности микрокапсул взаимодействуют с целевыми областями коллектора углеводородов и усиливают субстантивность микрокапсул к целевым областям коллектора. Текучая среда для доставки нефтепромыслового реагента подается для введения микрокапсул в желаемое местоположение внутри скважины и/или коллекторов, используя такие свойства, как плотность микрокапсул. Описаны способы получения текучих сред для доставки нефтепромыслового реагента, системы, содержащие текучие среды для доставки нефтепромыслового реагента, способы гидроразрыва пород в коллекторе и трассирования перемещения текучей среды в коллекторе углеводородов с использованием этих текучих сред.
