Hancheng Xiyuan Village 1# Water Supply Well Technology Design
摘要
No.1 water supply well in xiyuan village of hancheng city, as a new water supply project to solve the problem of water supply for residents, the quality of the well will directly affect the normal water consumption of urban residents in hancheng city. According to the geological data obtained in the early stage of geological exploration, this paper analyzes the characteristics of geological structure, formation lithology and hydrogeology in the design area, and designs the whole process of well completion by field investigation method, comprehensive analysis method and optimization selection comparison method. By comparing different formation lithology characteristics, design a reasonable hole structure, and then selects the TSJ-1000 water drill, rock bit drilling method, and determine the appropriate corresponding to the formation of flushing fluid and drilling into the water supply tube well drilling parameters, finally uses the cementing cement water stop, piston flushing method makes water supply tube well to meet the use requirements. This design is of great significance for safe, efficient and economical drilling, as well as improving well quality and extending the normal service life of the well.
