摘要
研究沧州地区虹吸水平井开采浅层弱渗透微咸水技术。在沧州地区成功施工一眼虹吸水平井,它巧妙地利用虹吸作用将浅部弱渗透地层中微咸水低能耗抽出。经长时间抽水试验得出:虹吸水平井水量足、开采成本低,可以作为新型供水水源用于农业灌溉;虹吸水平井长期抽取浅层微咸水水中含盐量逐渐降低,可以改良地下水质;虹吸水平井抽取浅层微咸水影响范围广,有利于大气降雨及地表淡水体的入渗及盐碱地的改良。
A horizontal well was successfully constructed in Cangzhou area.It siphons large volume of brackish water by low energy.From the pumping test,it can be drawn that shallow brackish water pumped by the horizontal well can be used as a new source of water supply for agricultural irrigation;the salt in shallow brackish water decreased and the groundwater quality can be improved;at the same time,due to the wide range of extraction influence and the extraction of shallow brackish water,this method can effectively resolve the saline problem if it be widely adopted.
