阳离子破乳剂DR-951的研制与应用

Development and Application of DR-951 Cation Demulsifying Agents

简单介绍了原油乳状液脱水过程中中间层形成的原因，并对其难以处理的原因进行了粗浅的解释，同时指出了华北油田岔河集断块原油脱水过程中存在的问题。在非离子型破乳剂的基础上，经酯化，在破乳剂分子中引入阳离子基团，合成出阳离子型破乳剂DR－951，介绍了它的合成路线并给出了工艺条件。室内脱水试验结果表明：DR-951在脱水过程中不产生中间层，脱水速度快，脱出水清，具有良好的适应性。现场应用试验结果也表明：DR-951用量少，脱后污水带油少，可以有效降低原油脱水温度，提高油田生产效益。DR-951现已投入批量生产并推广使用。

This article introduces the synthetic line of the demulsifying agents and shows its technological conditions. In door tests indicate that using DR-951, no middle layer emerges in the course of dehydrution, quicker in dehydration speed, dehydraed water is cleaner and having good adaptability. Spot application test shows that the adding amount of DR-951 less, oil in dehydrated water less, the dehydration temperature can be decreased and the oilfield production benefit increased. DR-951 has been put into batch process production and popularized.
