摘　　要：随着各大油田进入开采后期,“三采”和各种驱油技术的应用使得采出液中的水含量日益升高,乳状液的破乳难度也逐渐加大。总结归纳了目前常用的脱水技术及其特点,包括重力沉降法、热化学破乳法和电场力法。此外,还介绍了超声波、纤维膜及机械旋流等脱水新方法的研究进展,并探讨其应用前景。分析了常见原油脱水工艺存在的问题与不足,对3种新脱水工艺进行了综述,并对未来原油脱水研究方向进行了展望。As the major oilfields come to the late stage of extraction,the application of"three extraction methods"and various oil-driving technologies results in the increasing of the water content in the extracted fluid and has difficulties in emulsion-breaking there gradually.In this paper,the commonly-used dewatering techniques and their characteristics were summarized,including the gravity settlement method,thermo-chemical demuisification method and the electric field force.In addition,the research progress in new de-watering methods such as the ultrasonic wave,fiber membrane and the mechanical cyclone were introduced and their application prospects were discussed.Finally,both problems and shortcomings of familiar crude oil dehydration processes were analyzed,and three new dehydration processes were reviewed and the later research direction concerned was prospected.
