Abstract

Данное изобретение относится к жидкости на водной основе для применений в нефтяном месторождении, включающей неионные поверхностно-активные вещества, стабильные при температурах в диапазоне от 10 до 90°С, имеющие ГЛБ (гидрофильно-липофильный баланс) в диапазоне от 8 до 20 и растворимые в воде, с содержанием солевого раствора в диапазоне от 0 до 60 мас.% и, возможно, солей. Жидкость может быть легко использована в качестве раствора для заканчивания скважины с целью предотвращения образования инверсных эмульсий ″вода-в-масле″ или в качестве корректирующей жидкости для разрушения уже образованных эмульсий в нефтяных скважинах, в которых применяют буровые растворы на масляной основе.
