钻孔自流水的观测33.如果在钻探过程中,地下水从钻孔中流出或喷出,则钻探工作必须暂时停止,以便测量自流水的涌水量.此时,须记录钻孔深度,下套管的深度,并测量静止水位(水头),自流时钻孔的涌水量,水位下降,动水位和水温,并且要取水样进行分析.钻孔深度继续加深时,必须测量和记录自流现象停止时或涌水量显著减小时钻孔的深度和下套管的深度.钻孔的深度和下套管的深度须经过专门的检查测量后再记入记录薄.
Drilling of run-of-the-sea observations 33. Drilling work must be stopped temporarily to measure the influx of free-flowing water, if groundwater is to flow from or out of the borehole during drilling. The depth of the pipe, as well as the static water level (head), gushing water inflow, gravity, water level and water temperature at the gravity runoff, and the water sample to be analyzed for the drilling depth continue to deepen, the phenomenon of gravity flow must be measured and recorded The depth of the borehole and the depth of the lower casing when the amount of water gushing is significantly reduced The depth of the borehole and the depth of the lower casing shall be checked and measured before recording into the recording sheet.
