废弃无固相钻井液无害化处理技术研究与应用
Research and application of harmless treatment technology for waste non-solid phase drilling fluid
摘要
Abstract
The waste drilling fluid generated by drilling engineering can cause a series of impacts on the ecological environment,and it is required the comprehensive implementation of green exploration in the new round of strategic actions for mineral exploration breakthroughs,stricter requirements on the treatment technology of waste drilling fluid is posed.This article combines field research and laboratory experiments to analyze the pollution characteristics of the waste drilling fluid used at the Tengjia Gold Mine in Zhaoyuan,Shandong.Laboratory experiments are conducted to study the harmless treatment technologies for waste drilling fluid.The preferred agents of GPJ-1(a gel breaker),GXN-1(a flocculant),and GAC(a decolorizer)are optimized and processing by gel breaking,flocculation,adsorption,and decolorization treatment,followed by solid-liquid separation using centrifuges or filter presses,the solid phase is then treated with solidification.The experimental results show that after treatment,the pollution indicators of the waste drilling fluid have significantly decreased,meeting the secondary standards for comprehensive sewage discharge.The formulation"2%GPJ-1+0.5%GXN-1+1%GAC"was used to harmlessly treat the waste non-solid phase drilling fluid on the drilling site of Zhuguang project in Shaoguan,Guangdong,confirming the feasibility of harmless treatment technology.关键词
