摘要
随着小直径钻孔技术的进步与发展,该技术在工程中的应用越来越广泛.如何选择最为合理、经济、环保的钻进工艺是广大钻探工作者关注的课题.结合南方电网科学研究院直流工程深井接地极工程的特征,探讨了超厚灰岩层地层钻井的井身设计、设备选型与钻具组合和技术预防措施.工程首次揭露该套地层地分布特性和物探测井数据,为后续的深井接地极井设计和施工提供了技术支撑.
Abstract
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.
