Abstract:

In petroleum production, a large number of W/O, O/W or multiple emulsified emulsions are usually produced, resulting in greatly reduced production efficiency and serious environmental problems. The demulsifiers used in production have low demulsification efficiency, high cost, poor universality and insufficient safety. There is still more attention to develop efficient, universal, green and safe demulsifiers. Based on the analysis of the characteristics and stability mechanism of crude oil emulsion, the research progress of demulsifiers for different crude oil lotion were summarized. It mainly included polymer demulsifiers, biomass based demulsifiers, ionic liquid demulsifiers and nano material demulsifiers. Finally, the development of efficient demulsifiers and the future development trend of demulsification technology were put forward. It laid a foundation for the demulsification technology application of W/O, O/W or complex crude oil emulsions.

Key words: complex crude oil emulsion, ionic liquid demulsifier, biomass-based demulsifier, nanogenic material demulsifier, demulsification mechanism

摘要:

石油生产中通常产生大量W/O、O/W或多重乳化的复杂原油乳液,造成生产效率大大降低以及严重的环境问题。目前所使用的破乳剂破乳效率低、普适性差、成本高、安全性不够等,开发高效、普适、绿色、安全破乳剂仍备受关注。本文基于原油乳液的特点及稳定机制分析,综述了不同原油乳液的破乳剂研究进展,主要围绕聚合物破乳剂、生物质基破乳剂、离子液体破乳剂和纳米材料破乳剂的特点、适用范围及其应用效果进行全面总结,对相应破乳剂的破乳机理进行针对性地分析研究,并指出破乳剂机理的研究方法。最后,本文对复杂原油乳液的高效破乳剂开发进行展望,提出破乳技术的未来发展趋势,以期为W/O、O/W或多重乳化的复杂原油乳液的破乳技术应用提供一定借鉴与参考。
