Аннотация

Оценивалось влияние старения деэмульгатора на его характеристики, моделирующее хранение нефти на месторождениях, с использованием синтетической эмульсии вода/нефть, приготовленной из тяжелой нефти и минерализованной пластовой воды при концентрации 55 000 ppm. Были определены характеристики нефти и исследованы некоторые свойства деэмульгатора. Нефть, содержащая 11.6% асфальтенов, идентифицировалась как тяжелая, что способствует стабильности эмульсии вода/нефть. Эффективность деэмульгатора увеличивалась со временем старения, результаты свидетельствовали о том, что происходит простое испарение растворителя-добавки, концентрирующее его активное вещество.
