摘　　要：针对湖南省抗旱找水工作中遇到的问题及找水定井工作效果进行深入分析,发现湖南省多数干旱区无明显的区域构造。为解决该类地区水量贫乏、地质资料缺乏、找水难等地质环境问题,提出采用低高程点法查找隐伏富水断裂,圈定找水靶区的工作方法。通过该方法,成井率由59.3%提高到82%,单井平均涌水量由原来的163m^(3)/d增加到了214.4m^(3)/d。因此,低高程点法查找隐伏富水断裂的方法可为抗旱找水工作提供参考借鉴,提高了找水定井的成功率。A thorough analysis and research on the problems encountered in the drought resistance and water finding work in Hunan Province,as well as the effectiveness of water finding and well location work,have found that most arid areas in Hunan Province do not have obvious regional structures.In order to solve geological environmental problems such as water scarcity,lack of geological data,and difficulty in water finding in such areas,a low elevation point method is proposed to search for hidden water rich faults and delineate water finding target areas.Through this method,the completion rate of the well has increased from 59.3%to 82%,and the average water inflow of a single well has increased from the original 163m^(3)/d to 214.4m^(3)/d.Therefore,the low elevation point method for identifying hidden water rich faults can provide reference for future drought resistant water exploration work and achieve the goal of improving the completion power of water exploration and well determination.
