Abstract

Представлены композиция и способ, предназначенные для улучшения эффективности рабочей жидкости для множества обработок на нефтяных месторождениях. Композиция представляет собой твердую добавку в загущенной рабочей жидкости с диапазоном размеров, достаточно маленьких для обеспечения ее вхождения в поры пласта; она там необязательно формирует пробку, формируя внутреннюю фильтрационную корку, а после этого разлагается, образуя разжижитель для загущающей системы рабочей жидкости. Примеры подходящих для использования добавок включают воски, сложные полиэфиры, поликарбонаты, полиацетали, полимеламины, поливинилхлориды и поливинилацетаты. Разложение добавки может быть ускорено или отсрочено.
