为了能方便、快速、准确地获取小直径、大深度监测井中的地下水样品，研制了气体置换式地下水采样器。该采样器依靠水柱压力驱动地下水样品进入采样管，使用压缩气体驱动地下水样品流出地表。在采样深度500 m的单次循环采样中，采样器平均采样量为20 L/次；在同样深度的连续采样中，采样器最大采样量为40 L/h。详细介绍了采样器的技术原理、设计制作以及试验测试情况。

To obtain groundwater sample in monitoring wells with large depth and small diameter quickly, we developed air-exchange underground water sampler. The sampler use water pressure to drive underground water into sampling tube and then use compressed air to press the water sample out of the well to ground surface. For single cycle water sampling in 550 m well, the av-erage water sampling volume is 20 L per time; while for continuous water sampling in 500 m well, the average water sampling volume is 40 L per time. This paper gives a detail introduction to the principle, design and development and test condition of the sampler.
