摘要:
国家地下水监测工程建设由国土资源部和水利部联合立项申报,历经10余年的可行性研究和评估论证,最终由国家发展和改革委员会批准实施。项目财政投资20多亿元,覆盖全国31个省、区、市及新疆建设兵团,涵盖了全国7大流域和16个重要水文地质单元,共布设20401个地下水监测站点。项目的组织实施意义重大,事关地质环境、饮水安全和经济社会的可持续发展等民生问题。其中,钻探工程决定着国家地下水监测工程建设的质量、运行效果及使用寿命。本文针对项目“地域分布广、施工战线长、地质条件复杂”等特点,从组织管理、钻井结构设计、成井管材和钻进工艺选择等方面的关键问题进行了分析研究,并提出了具体建议。
Abstract:
The national groundwater monitoring well construction project is established and applied by Ministry of Land and Resources of the People's Republic of China and Ministry of Water Resources of the People’ s Republic of China, which is approved by National Development and Reform Commission with the experience of feasibility study and evaluation for more than 10 years.With over 2 billion yuan of the total financial investment, the project covers 31 provinces and Xinjiang Pro-duction &Construction Corps including 7 large basins and 16 important hydrogeological units with 20401 groundwater moni-toring sites.The organization and implementation of the project is of great significance, which is related to the livelihood is-sues of geological environment, drink water safety, economic and social sustainable development and so on.In this project, the drilling engineering determines the quantity, running effects and service life of national groundwater monitoring wells. In view of the characteristics of wide geolgraphical distribution, long construction lines and complex geological conditions of the project, this paper analyzes the key points of construction management, well construction design, pipe for well comple-tion and drilling technology selection with detailed suggestions.
