Abstract: Fracturing flowback fluid is complex in composition and difficult in treatment because it is rich in chemical additives and is affected by formation water and cuttings. Based on the comparison of relevant regulations on water environmental protection and fracturing flowback fluid treatment in shale gas development between China and the United States, we find out the following problems in the environmental supervision of shale gas development in China:the unified coordination organization for the environmental supervision of shale gas development has not yet been formed; the environmental regulations and standards related to shale gas development are not perfect; the basic scientific research is weak. Therefore, the countermeasures of shale gas fracturing fluid management in China are establishing on a sound regulatory system and carrying out the entire process environmental supervision, improving basic scientific research, and enhancing the technology and management system.

Key words: shale gas, fracturing flowback fluid, policies, regulations, enlightenment
