| 摘 要： | 庆阳地区地下水异常丰富,地面高程在1 060m以下的钻孔有不同程度的涌水现象,给钻探施工带来了诸多难题。本文通过对施工区水文地质条件的分析,提出了涌水治理措施,即平衡地层压力法、密封器止涌、套管隔水分水法、随涌钻进等方法。同时对涌水钻孔的测井、封孔方法给予了说明。

| Abstract: | During the construction of drilling hole for groundwater in Qingyang District, water burst accident always happened below 1060m above sea level because this position is abnormally rich in groundwater. Through analysis of the hydrogeological conditions in the work area, this paper put forward the solutions of water burst accident, such as the balance method of formation pressure, stoping gushing with sealer, water separation with water insulation casing, drilling while water gushing and so on. |
