摘要
选出具有代表性的乳化降黏稠油作为化学破乳研究的基准体系,使用目前较新的基于光散射原理的自动化检测方法———稳定性分析法,对破乳体系及过程进行实时动态脱水速度和脱水率的评价分析,与传统的瓶试法对比,二者的评价结果基本一致,但新方法较大地提高了效率和准确度。对脱出污水含油率和净化油含水率两项指标进行评价分析,说明针对经过乳化降黏处理的稠油体系使用化学破乳的脱水效果是符合现场要求的。
The visbreaking of heavy oil is the key technology for the heavy oil development and gathering.However,it will bring some new challenges to its following demulsification and dehydration treatment.This paper selects the typical heavy oil emulsion as the basis for chemical demulsification and adopts light scattering-based automatic detection method to evaluate and analyze the real-time dynamic dehydration speed and rate systematically.In contrast with traditional bottle-test method,by the new method the efficiency and accuracy can be improved greatly.The oil content ratio of dehydration and the water content ratio of purified oil are evaluated,indicating that the heavy oil system after visbreaking treatment followed by chemical demulsification and dehydration is suitable for field requirement.
