LTB低温高效稠油破乳剂的研制与评价

摘要

针对冀东油田高一联稠油，研制出LTB低温高效破乳剂。LTB破乳剂由3种组分复配而成，其最佳配比为1∶1.5∶1.0，与冀东油田原用破乳剂WYZ相比，LTB破乳剂具有破乳速度快，脱出水含油量低，油水界面齐等优点，可使原油破乳温度由70℃降至50℃，节约大量的能源，降低破乳成本。LTB破乳剂在低温下破乳速度、脱出水颜色、污水含油量等指标均明显强于冀东油田原来使用的破乳剂。%LTB demulsifier is compounded with three composition.Its optimumcompound rate is 1∶1.5∶1.Compared with the WYZ,original demulsifier used in Jidong oilfield ,LTB has the advantage of fast in demulsifying,low water content in dehydrated oil and clean in oil-water interface.It can decrease the dehydration temperature from 70℃ to 50℃ so a lot of energy saved and the dehydration cost decreased.
