摘要
为了解决横向水流条件下含水层的水文地质关键参数的计算,以钻孔水文测井所获取的人工井液电阻率测井曲线为研究对象.首先根据横向水流条件下地下水运动特征建立含水层的水文地质模型,其次,以此为基础应用地下水动力学、溶质扩散定律等推导计算均质的孔隙型、孔隙裂隙型含水层渗透速度的公式,并通过钻孔渗透速度计算模型消除钻孔导致的渗透速度畸变,引入自由系数推导计算非均质的裂隙型含水层渗透速度的计算公式,之后,应用该公式分别对非均质的岩溶、均值的孔隙、裂隙型含水层进行了含水层进行钻孔现场试验,并通过分层抽水试验进行验证,最终取得了不错的效果.研究表明,应用该模型可以解决横向水流条件下含水层水文地质关键参数的计算,进而为含水层涌水量的计算、富水性的评价、含水层非均质性评价以及地下水资源评价等水文地质工作提供服务.
In order to resolve the calculation of the hydrogeological key parameters of the aquifer under the condition of horizontal flow, taking the artificial well liquid resistivity logging obtained by drilling hydrological logging as the research object. Firstly, the hydrogeological model of aquifer is established according to the characteristics of groundwater movement under the condition of horizontal flow, secondly, on the basis of the model, the formulas of calculating the permeability velocity of the aquifer are derived by the law of groundwater dynamics and solute diffusion. The permeability velocity distortion caused by borehole is eliminated by the calculation model of borehole permeability velocity, the formula of calculating the permeability velocity of aquifer under different fracture types is deduced,then, using this formula, the permeability rate of Karst fissure, mean pore and fissure aquifer is calculated respectively, and verified by stratified pumping test. Finally, good results have been achieved. The results show that the calculation formula based on the model can solve the calculation of the key hydrogeological parameters of the aquifer under the condition of horizontal water flow by using the resistivity logging curve of the artificial well, then it provides services for the calculation of permeability and water inrush, the evaluation of aquifer's water abundance, the evaluation of aquifer's heterogeneity and the evaluation of groundwater resources.
