方法根据辽河油区曙光油田曙一区超稠油密度大、粘度高、油水密度差小，胶质、沥青质含量高的特点，采用超稠油掺不同比例稀释剂进行不同条件下热化学沉降脱水。目的选择适合于超稠油脱水的工艺条件，解决超稠油脱水的难题。结果超稠油掺入一定比例（8：2，7：3）的稀释剂，加入一定量的（200～300mg／L）破乳剂LH－2或RS－2，在沉降12h和8h时，超稠油脱水可达到油净水清。结论曙一区超稠油掺不同比例的稀释剂进行脱水，能够满足脱水生产的需要。
Methods According to the characteristics of high density heavy oil, high viscosity, low oil-water density difference and high content of colloid and asphaltene in Shuguang Oilfield, Shuguang Oilfield, Liaohe Oilfield, super-heavy oil and different proportions of diluent were used for thermochemical sedimentation under different conditions Dehydration. Objective To select the suitable process conditions for the dehydration of super heavy oil to solve the problem of dehydration of super heavy oil. Results Ultra-heavy oil was mixed with a certain proportion of diluent (8: 2, 7: 3) and a certain amount of demulsifier LH-2 or RS-2 was added at 200 ~ 300mg / L. Heavy oil dehydration can reach the net water purification. Conclusions Shu-1 super-heavy oil mixed with different proportions of diluent for dehydration, to meet the needs of dehydration production.
