Abstract

Предметом данного изобретения являются скважинные флюиды, включая их постоянный реологический профиль. С одной стороны, состав инвертно-эмульсионного скважинного флюида включает маслянистый флюид как дисперсную фазу инвертно-эмульсионного скважинного флюида, немаслянистый флюид как недисперсную фазу инвертно-эмульсионного скважинного флюида; эмульгатор и реологический модификатор, характеризующийся тем, что реологическим модификатором является полиамид, полученный в результате реакции аминоспирта, жирной кислоты и полиамина, такой инвертно-эмульсионный скважинный флюид имеет постоянный реологический профиль.
