水力压裂技术在油气田生产开发中被广泛使用, 在压裂过程中若注入地层中的压裂液发生泄露, 或者对返排压裂液处理不当, 将会给地下水、地表水等水环境带来严重的污染和破坏. 处理返排压裂液的六种方法, 每一种方法都有各自的特色及局限性. 从环境保护和节约成本等方面考虑, 重视对返排液处理后循环使用的研究具有意义深远.

Hydraulic fracturing te chnology was widely used in the process of oil and gas fields development. Much fracturing fluid was used in the fracturing process, if the leakage occured when it was injected into the stratum, or improper handling with the back fracturing fluid, will bring serious pollution and damage to water environment such as groundwater, surface water ect. By analyzing the six processing methods of the back fracturing fluid, concluded that each method had its own characteristics and limitations. Considering the environmental protection and cost saving, paying attention to the research of circular use of the back fracturing fluid has great significance.
