摘　　要：针对油田开发中压裂返排液的复杂性和处理难题,通过次氯酸盐氧化法制备了高效、绿色的Na_(2)FeO_(4)氧化剂,探究其在处理压裂返排液中典型污染物瓜胶的最优作用条件并对其进行了应用效果评价。通过氧化降解瓜胶的反应分析,揭示了Na_(2)FeO_(4)氧化瓜胶的机理,其条件参数和作用机理对今后的油田开发过程中压裂返排液的绿色高效处理具有重要指导意义。In view of the complexity and treatment problems of fracturing flowback fluid in oilfield development,a high-efficiency and green Na_(2)FeO_(4) oxidant was prepared by hypochlorite oxidation method,and the optimal conditions for the treatment of melon gum,a typical pollutant in fracturing flowback fluid,were explored and its application effect was evaluated.Through the oxidative degradation of guar gum,the mechanism of Na_(2)FeO_(4) oxidation of guar gum is revealed,and its conditional parameters and mechanism of action have important guiding significance for the green and efficient treatment of fracturing flowback fluid in the future oilfield development process.
