摘要
针对胜利油田废弃钻井泥浆浸出液COD值高的特点,以水泥、粉煤灰、添加剂A、添加剂B组成的复合固化剂,对废弃泥浆进行固化处理研究。通过正交试验,得到几种固化剂在处理废弃钻井泥浆中的最佳配比,其组分质量分数分别为:水泥10%、粉煤灰20%、添加剂A 3%、添加剂B 0.5%。实验结果表明,复合固化剂使用后可将泥浆浸出液的COD值从896.84 mg/L降低至72.35 mg/L。
According to the characteristics of the high COD of the waste drilling mud extracts in Shengli Oilfield, the solidification treatment of waste mud was studied by using the composite curing agent composed of cement, fly ash, additive A and additive B. Through orthogonal experiments, the optimum mass fraction proportion of several kinds of chemicals in the treatment of waste drilling mud was found out. cement tO%, fly ash 20%, additive A 3%, additive B 0.5%. The results showed that the COD of the slurry was reduced from 896.84 mg/L to 72.35 mg/L, when the composite curing agent was used.
