冀中平原深层地下水的开发与利用

The Development and Utilization of the Deep Subsurface Water in the Middle Plain of Hebei Province

七十年代中期,华北油田于冀中地区首次开发了400米以下深层地下水。由于平原深部水文地质条件较差,加之开采强度大,开采总量已超过25000万立方米,使地下水形势发生了急剧变化,下降漏斗迅速形成,导致水源产量锐减,抽水设施面临报废,生产成本日渐提高,油田工业、农业和生活用水之间的矛盾日趋尖锐。本文在分析了深层水文地质条件的基础上,探讨了油田供水方向,提出建设卫星水源,合理利用地表水源,开发利用地下成水资源的设想。

For the first time, the Huabei Oil Fields exploited the deep subsurface water below 400 meters in the centre area of Hebei during the middle of 70s. Because the hydrogeological condition in deep plains is rather poor, and the quantity of the development is great, the state of the sub-surface water was changed rapidly. This paper analyses the hydrogeological condition at deoth, discusses the supplying direction of water for the oil tields, effers the suggestions to make satellite water resources and to use the suface water properly as well as offers the idea of developing and using the salty subsurface water.
