冷家油田的原油由中粒、低粘、高粘稠油和特粘稠油组成，高粘稠油占总量的63．8％，混合后的原油粘度（50℃）仍在1500InP·8以上，属高粘稠油范围、辽河油田的稠油处理站脱水方式大部分采用稠油掺稀油加热降粘二段脱水工艺，一段为热化学沉降脱水，二段为电脱水。针对冷家油田 The crude oil in Lengjia Oilfield is composed of medium-grain, low-viscosity, high-viscous oil and extra viscous oil, which accounts for 63.8% of the total. The viscosity of crude oil after mixing (50 ℃) is still 1500InP · 8 Above, is a high viscosity oil range, most of the heavy oil processing station dewatering method of Liaohe Oilfield heavy oil blending thin oil heating viscosity reduction two dehydration process, one for the thermochemical precipitation dehydration, two paragraphs for the electrical dehydration. For cold oil field
