宁夏宁东地区废弃冲洗液无害化处理技术初步研究

Preliminary study on harmless treatment of waste drilling fluid in the Ningdong area of Ningxia

摘要:

宁夏宁东地区作为国家级能源基地，近年来布置和实施了大量的岩心钻探工程，产生的废弃冲洗液数量大，由于废弃冲洗液处理方式比较单一，对周边环境有一定的破坏和影响。通过对宁东地区废弃冲洗液处理方式的调查研究，选择固化法对废弃冲洗液进行了处理，产生的污水和固化体满足国家相关排放标准，形成了一套适合类似地区废弃冲洗液处理方法，有助于保护宁东地区脆弱的生态环境。

Abstract:

As a national energy base， the Ningdong area of Ningxia has deployed and implemented a large number of core drilling projects in recent years， resulting in a large amount of waste drilling fluid. Because the disposal method of waste drlling fluid was relatively simple， it has brought some damage and impact on the surrounding environment. Through investigation and research on the treatment methods of waste drilling fluid in the Ningdong area， the solidification method was finally selected to treat waste drilling fluid. The produced waste water and solidified substance meet the relevant national discharge standards. A set of disposal methods suitable for waste drilling fluid in similar areas has been developed， which is helpful to protect the fragile ecological environment in the Ningdong area．
