洼38稠油高温脱水现场试验

Field Test of Wa38 Heavy Oil High Temperature Dehydration

以室内试验数据为基础，对洼38稠油进行了纯化学高温脱水现场试验。现场试验结果表明，油中含水为19％～20％，加入30mg／LKY－6高温破乳剂，脱水温度95～98℃（停运电脱水器）的条件下，可使净化油含水达到0．2％～0．8％，污水含油小于0.3％。并找出了最佳脱水温度下的原油粘度范围是50～60mPa·s。最后，还对影响稠油高温脱水的主要因素：脱水温度、破乳剂类型及用量进行了分析研究。

Based on the indoor test,the authors make chemicalhigh temperature dehydration field test on Wa 38 heavy oil. Test result shows that,when water cut in oil is 19% ~20%,adding 30mg/L KY-6 high temperature deemulsifying agents and dehydration temperature is 96 ~ 98℃, 0. 2% ~ 0.8% water cut in treated oil can be obtained and oil cut in sewage less than 0.3%. The authors also find out that under optimum temperature,crude viscosity range is 50~60mPa. s.
