摘要
本文论述了放射性同位素示踪测井方法及单井同位素地下水流向流速仪的构造、原理及特点:^(131)I作示踪剂,用LID和IC作接收器.采用萤光照相定方位,流向误差<±10°,测深500m.文中着重介绍了该方法在喀斯特地区地下水均衡试验场中的应用实例.通过流场动态参数测定,正确划分了试验场地下水边界、补给关系.采用这种新的水文地质手段,可提高水文物探效率,为该试验区节约打井费用40-50万元.
The paper discusses a radioisotope trace method for determining the undergroun water flow in boreholes, and introduces the structure, principle and characteristics of the radioisotope tracer flow-meter. IC and TLD arc used in the orientation fluoragraph. The error is below±10°and the depth about 500 meters. The paper also presents an experiment to use the method in the balance testing field in a K arst areas. We demarcated the boundaries and obtained the supplementary relationship of the underground water by determining the trends parameters of the underground water flow. It is a new method enabling hydrologists to detect underground water flow raise efficiency, and save money. 400-500 thousand yuan have been asaved at the teasung field
