辽河稠油破乳脱水综合技术实验研究

稠油在辽河田具有较大的产量，主要采用热——化学沉降脱水技术进行脱水，存在耗时长、耗能高、耗剂量大的现象。在采用热——化学沉降脱水工艺的基础上，引入超声波物理场，与现有的热——化学沉降脱水工艺相结合，实现声、化学和热联合作用，对辽河稠油进行破乳脱水研究。研究证明可以大幅度降低时间和化学药剂用量，降低能耗，提高脱水效率。

Experimental study of comprehensive techniques for dehydration and demulsification of heavy oil in Liaohe Oil -field

Liaohe Oilfield has a great output of the heavy oil. Thermo-chemical setting is adopted as the main technolgy of dehydration in which the dehydration in which the defect includes time- consuming ,energy-consuming, and agent-consuming. To study the emulsion breaking and dehydration of heavy oil in Liaohe Oilfield,on the basis of thermo-chemical technology,the ultrasonic physical field is introduced to realize the combined effect of the acoustic wave,chemicals and thermo. The research shows that the introduction of ultrasonic physical field can greatly reduct the settling time, the chemicals dosage and the energy-consumption. As a result,it improves the efficiency of dehydration.
