一、序言目前,国内外研究原油破乳剂的主攻方向是:低温、快速、适应性强。低温的目的是节约能源;快速则为了提高处理原油的能力,缩短处理周期;适应性强是为了克服破乳剂专一性强的弱点,使一种破乳剂能满足不同地区不同性质的原油破乳。为此,研究低温、快速、适应性强的原油破乳剂,对于进入高含水采油阶段的油田,保障原油脱水质量,节约 First, the preamble At present, the main direction of research crude oil demulsifier at home and abroad are: low temperature, rapid, adaptable. The purpose of low temperature is to save energy; fast in order to improve the ability to handle crude oil, shorten the processing cycle; adaptability is to overcome the weakness of the demulsifier specificity, so that a demulsifier to meet the different regions of different nature of the crude oil demulsification . To this end, the study of low temperature, rapid, adaptable crude oil demulsifier, for entering the high water cut oil recovery stage, to protect the quality of crude oil dehydration, saving
