Abstract
Досліджено високов’язкі нафти Яблунівського родовища (Україна, Полтавська обл). Нафти розбавляли газовим конденсатом для зменшення в’язкості, потім деемульгували різними деемульгаторами. Встановлено, що нафти доцільно розбавляти важким газовим конденсатом, зневоднювати нейоногенним деемульгатором ПМ-1441 марки А на основі блоккополімерів оксидів етилену та пропілену. Ступінь зневоднення при цьому сягає 95 %.
High-viscosity crude oils from the Yablunivske field (Ukraine, Poltava region) have been studied. The oils were diluted with gas condensate to reduce viscosity, and then various demulsifiers were added. It was established that it is expedient to dilute oil with heavy gas condensate and dehydrate it with PM-1441 brand A non-ionogenic demulsifier, based on block copolymers of ethylene and propylene oxides. The dewatering degree was found to be 95 %.
