基于WellTester的岩溶含水层水文地质参数估算

摘要

WellTester是计算地热含水层水文地质参数的软件，该软件通过对水压力过程曲线进行拟合，进行参数计算。该软件界面友好、操作简单，且具有输出单井报告功能。文章对WellTester软件各模块及各界进行简要介绍的基础上，以“北京岩溶水资源勘查评价工程”中新建岩溶水井为例，对各个操作步骤进行了介绍。通过对比分析WellTester软件与经验法的结果，表明该软件可对岩溶裂隙含水层的水文地质参数进行计算，且该软件对成井质量评价有一定指导意义。目前该软件还未广泛应用于岩溶裂隙含水层，为获取较多的水文地质参数，笔者认为该软件在我国具有一定的推广价值。%The WellTester is a software to evaluate the hydrogeological parameters. By iftting the progress data of pressure collected in one pumping well, the parameters of the aquifer can be modeled. The WellTester has friendly interface and can be easily operated. It can export a complete well testing report. After simple introduction to modules and interface of WellTester, an example on the well of XL-K-1 which is one of 42 wells of the Program of Investigate and Evaluate of Karst Ground Water Resources in Beijing was given. Also, the detail operating steps of the software was described. Through comparing the results of the traditional method and the modeling results of this paper, the software can be used to acquire the hydrogeological parameters of the ifssured rock quickly. Beside the several key parameters, the skin factor evaluating the quality of the well can be calculated. We hope that the software will be used in calculating the parameters of karst widely in the future.
