摘　　要：水文地质学通常以水头高度直接表达开采过程中的压力变化。随着井深增加，水温对水头高度的影响越来越大，需要采用下井仪器测量井底压力。井下压力测试资料统计分析证明，利用在地表上容易观测到的水位、水温资料计算出的井下压力，达到了与下井仪器相同级别的工程测量精度。In hydrogeology the pressure variation during exploitation is often indicated directly by water head height. The influence of water temperature on water head height becomes bigger as the well depth increases. The pressure at the well bottom has to be measured by instruments in the well. The analysis of data for pressure at the well bottom shows that the well pressure acquired through calcula tion by using the water level and water temperature which are easily observed on ground has the same precision in measurement as the instruments used in well.[
