甘肃地矿局水勘院水文工程公司承担的甘肃能源基地地下水资源Q2勘查钻孔施工任务,在用准311钻具二开钻进到500.00m后下准273井管时,发生井管遇阻被卡事故。井管下到孔深395m处,既不能提升,又不能下到预定深度500m的位置。经过认真分析后,采用“飞管止水”法成功处理井管事故,最终使Q2井达到设计要求,圆满完成施工任务。 Gansu Institute of Geology and Mineral Resources Hydropower Engineering Institute of water resources bear the Gansu base of groundwater resources exploration drilling task of Q2, with the prospective 311 drill two open into the next prospective 273 well after 500.00m well tube wells encountered resistance Be stuck accident. Wells down to 395m hole depth, neither to enhance, but also can not go down to a predetermined depth of 500m position. After careful analysis, the “fly-pipe stop” method was successfully used to deal with the well pipe accident, and finally the Q2 well met the design requirements and the construction task was satisfactorily completed.
