中文摘要:为打赢大气污染防治攻坚战和燃煤替代任务,平顶山市市委市政府委托河南省有色金属地质矿产局组织开展平顶山地区地热勘查开发工作。根据对区域地质情况和地层特点,河南省有色金属地质矿产局自行设计并组织施工了平顶山北地热示范区PBR01井。文章从钻探设备选型、施工工艺选择、钻井液配置等方面介绍了项目设计和施工的全过程;通过钻井的施工,解决了本地区大口径深孔钻进难题,为本地区后续开发应用起到了良好的示范作用;通过对钻时曲线的分析,掌握了本地区不同地层钻进效率情况,提出了提高大直径硬岩钻进效率的方案。
中文关键词:地热井施工  钻井液配置  钻时曲线分析  钻进效率研究
 
Drilling technology for PBR01 geothermal well in North Pingdingshan Geothermal Demonstration Zone
Abstract:In order to win the battle of preventing and controlling air pollution, fulfil the task of replacing coal burning, the Pingdingshan Municipal Party Committee and Government entrusted Henan provincial Non-ferrous Metals Geological Mineral Resources Bureau to organize the geothermal exploration and development in Pingdingshan area. According to the regional geological conditions and stratigraphic characteristics, Henan Provincial Non-ferrous Metals Geological Mineral Resources Bureau designed and organized the construction of well PBR01 in north Pingdingshan geothermal demonstration area. This paper introduces the whole process of the project designing and constructing from the aspects of drilling equipment selection, construction technology selection and drilling fluid configuration. Through drilling construction, the problem of large-diameter deep hole drilling in this area has been solved, which has played a good demonstration role for the subsequent development and application in this area. Through the analysis of the drilling time curve, the drilling efficiency of different areas in this region is understood, and the scheme to improve the large diameter drilling efficiency in hard rocks is put forward.
