| 摘 要： | 安塞油田近几年产量不断攀升，给干旱少雨、地下水资源十分贫乏的安塞地区供水带来了很大困难。为满足采油厂的需水要求，需要对谭家营水源地的取水能力进行评估。水源地的取水工程拟采用渗渠取水方式。根据延河河谷区概况建立延河水资源数学模拟模型，使用MODFLOW计算模拟渗渠在不同设计方案下的取水量。通过对渗渠取水地区地下水补给量、河流径流量的分析，并和渗渠开采量进行比较，确定渗渠取水量1774m3／d是有保证的。

| Abstract: | The rising production of Ansai oilfield has brought great difficulty for water supply in Ansai area, and it is short of rain and groundwater in the region. The paper makes an assessment on water intake capacity of Tan jiaying water source to evaluate the intake quantity which will meet requirement of production plant. In the evaluation test, water is gathered from seepage channels. Based on the mathematical model of Yanhe water resources, which is established with the consideration of general situation in Yanhe valley, infiltration gallery water withdrawal in different schemes are calculated by MODFLOW. The comparison between groundwater recharge and river runoff in tested area and seepage channel water withdrawal indicates that water supply is above 1 774 m3/d, which meets the requirement of production plant. |
