采用微泡沫钻井液进行钻井过程中，会产生大量废水。泡沫钻井液废水含有大量表面活性剂，化学需氧量（COD 值）较高，直接排放会对环境造成极大的影响。简要分析了表面活性剂对环境可能造成的影响，按照国家标准对废水进行了检测，依据实际情况，制定实验并分析结果，通过消泡以及絮凝过程，除去废液中大量的表面活性剂，并成功使 COD 值从4875降到184，证明方案切实有效。

During drilling with the micro foam drilling fluid, a lot of waste water will be produced. Foam drilling fluid waste water contains a large amount of surface active agents and also has high chemical oxygen demand (COD) value, direct emission of which will cause a great impact on the environment. In this paper, the effect of surfactants on the environment was analyzed. The waste water was detected according to the national standard. Based on the actual situation, the experimental scheme was formulated, and the results were analyzed. The results show that, by defoaming and flocculation process, a large amount of surfactants can be removed from waste water, and the COD value can be decreased from 4875 to 184. The experiment results have proven that the scheme is practical and effective.
