Abstract: 
Парафінисті відклади створюють значні перешкоди в забезпеченні текучості сирої нафти, оскільки викликають аномалії тиску в трубопроводі, зменшують його прохідний діаметр, призводять до штучних засмічень. Для двох нафт західного регіону України, Долинського і Бориславського родовищ, за допомогою методу холодного пальця було визначено кількість відкладів. Показано динаміку росту кількості відкладів у часовому інтервалі до 24 год. Проведено оцінювання ефективності депресора Dodiflow 5236 як інгібітора утворення відкладів. Встановлено, що депресор зменшує кількість утворених відкладів у 1,5-2,5 разів. Крім того, депресор знижує швидкість осадження парафіну і змінює структуру кристалів. Показано, що кількість відкладів, утворених із сирої нафти і нафти з депресором, залежить не тільки від фізико-хімічної характеристики нафти, але й від різниці температур між нафтою та стінкою.
