摘　　要：针对压裂返排液成分复杂,处理过程中有机物含量难以表征这一特点,以压裂返排液中主剂羟丙基瓜尔胶为研究对象,分别采用测定体系化学耗氧量(COD)和总有机碳(TOC)方法研究了有机物含量、氯离子含量和氧化处理对其含量表征的影响。结果表明:COD表征压裂液返排液的有机物含量有较大局限性,TOC比COD更适合表征羟丙基瓜尔胶溶液中有机物的含量。The composition of the flowback fluid was complex and it is difficult to characterize the organic matter content. The hydroxypropyl guar gum, which is the main components of fracturing fluid, was chosen as the research project, the effect of the content of organic matter and cholrine ion, oxidation treatment on the identification of the organic matter content of fracturing liquid were investigated by measurement of chemical oxygen demand（COD） and total organic carbon （TOC）, respectively. The results showed that there was larger limitation when using COD method to characterize liquid organic matter content of fracturing fluid, while TOC was more suitable to charaterize the content of the organic matter of hydroxypropyl guar gum solution.
