含聚合物原油乳化液破乳剂的研究

Polymer containing crude oil demulsifier effluence research

选用10种破乳剂对大庆油田含聚原油乳化液进行破乳脱水实验,对效果好的3种破乳剂进行复配。结果表明,TA-1031/TEF-16按照1∶1(质量比)进行复配,在温度50℃、加量150 mg/L时,120 min脱水率可达到97.4%,污水含油92 mg/L。

Using 10 kinds of demulsifier on Daqing oilfield polymer containing crude oil emulsion carried out dehydration test. The result showed that TA-1031/TEF-16 carried out in accordance with the 1 ∶ 1 ratio of distribution,the temperature of 50 ℃,and 150 mg/L,120 min dehydration rate can reach 97. 4%,sewage in oil 92 mg/L.
