Application of Small-diameter Geological Exploration Drilling Technology in Deep-well Earthing Electrode Engineering
Small-diameter drilling technology is more and more widely used in engineering with the progress and development of it.How to choose the most reasonable,economic and environmental protection drilling technology is the concern of the majority of drilling workers.Combining with the characteristics of deep-well earthing electrode engineering of China Southern Power Grid Research Institute,the drilling well design,equipment selection,drill assembly and technical preventive measures in ultra-thick limestone stratum were discussed.The project revealed the formation distribution characteristics and geophysical logging data for the first time,which can provide technical support for the subsequent design and construction of deep-well earthing electrode.
