地矿部水文地质技术方法研究队钻探科经几年努力,研究出几项水文地质钻探冲洗液成果,均已通过部级鉴定验收。 一、水井-1号土 水井-1号土是以膨润土、白垩土为主料及有关化学处理剂经科学配方优选而成。适用于第三系、第四系水文地质勘探供水井钻井用冲洗液。经中国地质工程公司、河南水文地质一队等单位试用证明该钻井液在保护含水层、简化洗井工序、缩短洗井时间、提高成井质量、降低钻探总成本等方面均取得了显著效果。
After several years of hard work, several research projects of hydrogeological drilling fluid have been approved by the Ministry of Geology and Mineral Resources. First, No. 1 Well No. 1 Well No. 1 soil is bentonite, chalk-based materials and the chemical treatment agent selected by the scientific formula. Apply to the Tertiary, Quaternary hydrogeological exploration water supply well drilling fluid. The trial by Geological Engineering Company of China, Henan Hydrogeology Team and other units proved that the drilling fluid has achieved remarkable results in protecting the aquifer, simplifying the well washing process, shortening the flushing time, improving the well completion quality and reducing the total drilling cost.
