航空定向技术在地下水流速流向中的应用研究

将高科技的航空定向技术与同位素稀释测井技术相结合，研制出一种智能化的地下水动态参数测量仪。在天然流场下的单井中测量了地下渗透流速、流向；垂向流速、流向，并对仪器的结构、原理、工作过程作了详细的讨论，该测量仪可广泛地应用于堤坝渗漏路径的探测、水源地的地下水勘察、煤矿涌水预测、环境保护、农田地下水溶质运移等。

Measuring Velocity and Direction of Groundwater by Using Directional Aviation Techniques

A new intelligent meter by combining directional aviation techniques with isotope tracer dilution logging is manufactured. Assisting with isotopic and natural trace technique, it may measure velocity and direction of groundwater, permeability coefficient, coefficient of hydraulic conductivity, static head, hydraulic slope and flow direction of each layer, recharge relation between each two aquifers. The action and the configuration of the meter are discussed. The result can be widely used in many fields, such as seepage monitoring in abutment and river bank, ground water development, water conservation measure in agriculture, prediction of water yield in mining, the displacement of pollutant in groundwater, water resources research, environmental protection, etc.
