摘要
分析了钻井作业对地下水污染的特点、污染途径,针对性地提出了钻井作业对地下水污染的预防措施,以及污染物处理技术,其中氧化还原技术、气体抽取技术、环境生物技术主要用于有机物污染治理,SRB技术、废弃钻井液固化技术、钻井液转换为水泥浆(MTC)的固井技术可用于处理废弃钻井液。钻井引起的污染治理应以"预防为主,防治结合",切实推行清洁生产和HSE管理。
This paper analyzes the characteristics and ways of underground water pollution caused by drilling operations.It puts foreword the precautionary measures and pollutant treatment technology of underground water pollution caused by drilling operations.Among the pollutant treatment technology,oxidation reduction technology,gas extraction technology and environment organism technology are mainly used for organism pollution treatment;whereas SRB technology,waste drilling fluid solidification technology and drilling fluid to cement conversion technology(MTC) can be used to dispose waste drilling fluid.The pollution treatment caused by drilling should follow the rules as 'prevention in the first place and integrating prevention with control'.Cleaner production and HSE management should be effectively implemented.
