随着油田开发进度的加快和对环保要求的提高，如何处理和利用含油污泥已成为各大油田企业亟待解决的问题。本文综述了国内外含油污泥回收处理技术的现状，类比解析了溶剂萃取、化学清洗、调质-机械分离、热解、超声、微波、回注调剖、电动力学、冷冻熔融等处理技术的工艺流程和特点；并结合实际分析、探讨了延长油田含油污泥处理现状与发展方向。

With the acceleration of exploration speed and the upgrade of environment protect requirement，the disposement and use of the oily sludge has become an urgent problem for every oilfield and petroleum company. In this article，the present situation about domestic and foreign oily sludge treatment technology was summarized，such as solvent extraction，chemical cleaning，conditioning-mechanical separation，pyrolysis，ultrasonic，microwave，reinjection/profile，electrokinetic and freeze/thaw. In addition，a comparative analysis of the flow features and process is then undertaken with each of these treatments. What’s more，combined with the actual situation，the current situation and development of oily sludge treatment in Yanchang oilfield were analyzed.
