摘　　要：随着我国油气田勘探开发力度加大和新环保法的实施,油田开采过程中耗水量大和污水处理问题是我国油气田企业面临的共同难题。从污水余热回收、污水回注、压裂液重复利用、钻井废水再利用四个方面,介绍了国内油田产出水再利用技术研究进展与应用现状,指出目前存在的污水余热再利用应用范围不广、回注污水利用不合理、化工原料未回收利用等主要问题。并通过文献调研,展望了油田污水再利用技术的发展方向,指出需从污染源头防控入手,研发更加经济环保的液体配方,并深入研究从污水中取热、取水及取化工原料的循环再利用技术,因地制宜制定相应的水质及污水配伍性实验评价标准,实现从源头至末端治理相结合的油田污水清洁生产。With the increase of China’s oil and gas exploration and the implementation of the new environmental protection law,the large consumption of water and the problem of sewage treatment had been the major issue for oil and gas enterprises in China.The paper summarized the relevant research and application f domestic wastewater reuse technology,including,waste heat recovery,sewage re-injection,fracturing fluid reuse and drilling wastewater reuse.Pointed out the main problems and the future development direction of current sewage reuse technology.According to literature research,the current sewage reuse technology is in the stage of heat extraction and water intake.The reuse of chemical materials needs further study;the sewage treatment technology is uneven and it is necessary to combine wastewater treatment technology to improve sewage reuse technology;studying environmentally friendly liquid formula to prevent and control pollution from the source;formulating water quality evaluation standards and relevant experimental evaluation standards for compatibility of wastewater based on local conditions.
