海上热采添加剂对原油破乳脱水的影响

Impact of thermal chemical additives on crude demulsification and dehydration in offshore oilfield

海上稠油热采技术是近年来针对海上稠油开采发展起来的一项新兴技术。该技术在取得了不错的增油效果的同时,也给海上原油处理带来了一些困难。本文针对海上稠油热采原油脱水困难的问题,研究了化学添加剂对原油破乳脱水的影响,对海上稠油热采化学添加剂的使用具有实际指导意义。

The technology of thermal recovery for offshore heavy oil field has become a new but advanced technology with the development of offshore heavy oil. Until now, this technol- ogy has made satisfied effects in oil production. However, it causes the Demulsification and dehydration of produced fluid from the heavy oil. To this problem, the influence of thermal chemical additives in oil thermal production has studied, which provides guideline for appli- cation of thermal chemical additives in the oil thermal production of offshore heavy oil field.
