Abstract

Жидкости для обработки, содержащие соли, поверхностно-активные вещества, взаимные растворители и волокна, могут быть применены для удаления из скважины фильтрационной корки, которая была осаждена из буровых растворов. Буровые растворы могут быть на водной основе, на масляной основе, на синтетической основе или эмульсиями. Волокна могут быть выбраны из полимолочной кислоты, целлюлоз, полиэстеров, поливиниловых спиртов и полиэтилентерефталатов. Комбинация прямого и извитого волокна присутствует в жидкости для обработки.
