Treatment Technology of Waste Drilling Fluid in Drilling Engineering and the Progress

摘要:

介绍了国内外废钻井液处理方法的发展现状，研究了废弃钻井液对环境的危害和影响，阐述了坑内填埋、固液分离法、固化处理、循环使用以及几种特殊的钻井液处理技术。在此基础上，提出了一些建议，如开发新型环保钻井液和钻井液添加剂；加强固控，减少废钻井液的排放；综合开发利用如微生物法等新技术等,为其他类似区域钻井工程的环境保护提供参考。

Abstract:

The treatment technologies of waste drilling fluid in drilling engineering both in China and abroad were introduced. The hazard and influence to environment by waste drilling fluid was studied. The treatment technologies and methods such as the in-pit landfill, solid-liquid separation, solidification and recycling use were discussed. Some suggestions were put forward, such as developing new environmental protection drilling fluid and additive, strengthening the solid control, reducing the discharge of waste drilling fluid and comprehensively developing new technology like microbial method. All the above can be the reference to environmental protection in other similar areas.
