    摘要:

    随着油气田开发规模的日益扩大,压裂作业用水量逐渐增大与压裂返排液产生量大、返排液无法直接外排的矛盾日益突出。将返排液进行处理后再回用无疑是目前解决该难题的有效途径。针对我国压裂返排液重复利用研究与应用现状,从返排液处理过程中面临的技术问题、可回收压裂液体系的研发、返排液处理工艺及处理装置的改进等几个方面进行了系统介绍,指出处理后回用是返排液处理的最佳途径,也是未来油气田工业发展的必然趋势。返排液回用技术应该从可回收压裂液体系的研发及返排液回用处理工艺改进两方面入手,进一步完善和推广该技术在油气田开发过程中的应用。针对目前返排液回用技术存在的问题提出了建议,以期为我国返排液重复利用技术的发展提供指导。

    Abstract:

    With the increasing expansion of the development scale of oil and gas fields,the contradiction between the gradual increase of water consumption for fracturing operation and the large amount of fracturing flowback fluid that cannot be directly discharged is further highlighted. It is undoubtedly an effective way to solve this problem that treat the flowback liquid and reuse it. Aiming at the reuse research and application status of fracturing flowback fluid in China,this paper systematically introduced the technical problems faced in the process of flowback fluid treatment,the research and development of recyclable fracturing fluid system,the improvement of flowback fluid treatment process and treatment device. Treating and reusing the flowback liquid was the best way and was also the inevitable trend of future development of oil and gas field industry. The development of flowback fluid reuse technology should start from the research and development of recyclable fracturing fluid system and the improvement of flowback fluid reuse treatment process,so as to further improve and popularize the application of this technology in the process of oil and gas field development. In view of the problems existing in the current reuse technology of flowback liquid,some suggestions were put forward in order to provide guidance for the development of reuse technology of flowback liquid in China.
