摘　　要：针对安塞油田部分水源井无水停运问题,引入了"地下水资源富集程度"概念,并利用数值模型分析了安塞油田区域地下水资源富集程度和水源井停运原因,提出了水源井挖潜对象筛选原则。结果表明:研究区西北部主要河流河谷区的地下水资源富集程度较好,西部黄土丘陵地带以及东部河谷区地下水资源富集程度较差,东部黄土丘陵地带地下水资源富集程度差。水源井无水停运主要因为水源井布设在地下水资源富集程度较差区域。在挖潜对象筛选时应避开现状开采井过于集中、局部开采强度过大的区域(超采区),应分布在地下水富集区,并注意与现有正常运行的油田水源井及地方水井之间的合理井间距,减少互相干扰。Aiming at the current issue that the water source wells are out of service in Ansai oilfield,this paper introduced the concept"enrichment degree of groundwater resources",and established numerical model to analyze the degree of groundwater resource enrichment as well as the causes of wells shutdown,and proposed the principle of selecting potential water source wells.The results show that the enrichment degree of groundwater resources from relatively rich to relatively poor to poor are the northwestern main river valleys,the western loess hills and the eastern valleys,and the eastern loess hills respectively in the study area.The main reason why the water source wells shutdown is that they are mostly located in areas with poor groundwater resource enrichment.During the selection of potential mining objects,it is important to avoid the areas where the current mining wells are too concentrated or the local mining intensity is too high such as over-mining areas.They are supposed to be located in the groundwater-rich areas.Besides,it is crucial to consider the reasonable distance among those existing normal operating oilfield and local water wells to reduce mutual interference.
