大庆北四联合站地处萨北东部过渡带,日处理液量12000米~3,原油综合含水86％。该过渡带原油不但含蜡量高、凝固点高、粘度高,而且机械采油井和作业井多,单井地面流程又为热油伴随和热油洗井。因此,破乳剂的投加量不容易掌握,从而使外输油含水质量合格率达不到98％。北四联原油是采用二段脱水,即包括热化学
Daqing North Fourth United Station is located in the eastern Saba transition zone, daily processing capacity of 12000 m ~ 3, 86% of the combined water content of crude oil. The transitional crude oil not only has high wax content, high freezing point and high viscosity, but also has many mechanical oil wells and working wells. The single well surface flow is accompanied by hot oil and hot oil well washing. Therefore, the amount of demulsifier dosage is not easy to grasp, so that the water quality of foreign oil passing rate of less than 98%. North quadruple crude oil is the use of two dehydration, that is, including thermochemistry
