摘要
地下含水层含水量主要是指含水层的可开采能力,其表征参量为单孔单位涌水量。单位涌水量是表征地下含水层出水能力大小的重要指标,常规求取方法为抽水试验法。本文提出了一种利用水文测井数据预测单井涌水量的技术方法,并构建了相应的软件系统,实现精度误差低于30%的单井涌水量预测,预测精度稳定可靠。该技术成果在水文地质调查中与少量钻孔抽水试验相结合,可节约大量人力物力成本,是一种新型的地下水资源评价技术手段,可少在水文与水资源调查中推广使用。
Underground aquifer water content refers to available capacity of the aquifer,the characterization parameter is borehole unit water inflow.Unit water inflow is an important parameter which indicates the aquifer capacity.The conventional calculation method is pumping test.In this paper,a new specific capacity forecast technique is proposed based on hydrogeological logging data and the software system is constructed.The forecast accuracy is stead and reliable,and the error is lower than 30% by the technique.It is a new method of groundwater evaluation.Combined with a small number of pumping tests in hydrogeologic survey,a huge laborer and material resource will be saved.This technique is worth promoting in hydrogeologic and water resources investigation
