摘要
废弃冲洗液无害化处理是落实绿色勘查理念的一项重要工作。通过室内测试分析与现场调研,对地质钻探不同领域的钻孔废弃冲洗液进行污染特性研究,了解其基本性质以及对环境的影响方式。结合湘桃地2井废弃冲洗液开展脱稳技术室内研究,对破胶剂及絮凝剂进行了优选,并获得了脱稳处理的基础配方。实验结果表明,经过处理后废弃冲洗液能实现快速脱稳絮凝,COD、悬浮物、色度等污染指标大幅下降,为下一步深度处理实现无害化排放创造了有利条件。
Harmless treatment of waste drilling fluid is an important job for us to implement the concept of green exploration.Through laboratory test analysis and site survey,the pollution characteristics of waste drilling fluid in different fields of geological drilling were studied,and also its basic properties and its influence on the environment were investigated.With waste drilling fluid from Well Xiangtaodi2 as the subject of study,research was done on the destabilizing technology with optimization of the gel breaker and flocculant materials to obtain the basic formula for destabilization treatment.The experimental results showed that de-stabilization and flocculation can be achieved of the waste drilling fluid rapidly,and pollution indicators,such as COD,suspended solids,chroma,declined significantly;which can create favorable conditions for the next deep treatment to achieve harmless emissions.
