水泥浆随钻无害化处理

Harmless Treatment of Fresh Water Mud While Drilling

钻井后废弃钻井液给环保带来了极大的压力,因此对废弃钻井液进行无害化处理,不仅是钻井工艺的必要过程,也是环境保护的需要。分析了淡水泥浆的处理机理,以及优选了3种处理剂并探讨了各自的处理效果,分析表明,氯化铝处理效果最佳。

Waste drilling fluid after drilling has brought great pressure to environmental protection,so the harmless treatment of waste drilling fluid is not only a necessary process of drilling technology,but also the need of environmental protection.The mechanism of freshwater slurry treatment was analyzed,and three kinds of treatment agents were optimized.The results showed that aluminum chloride treatment had the best effect.
