Evaluation of hydraulic tomography and data integration for improved estimates of suburface hydraulic parameters

水力层析成像（HT）作为一种新的现场技术正在迅速兴起，用于对水力传导率（K）和比存储（Ss）的地下非均质性进行成像。特别是，HT 涉及 (1) 通过井网进行连续含水层水力测试，以及 (2) 联合分析完整的数据集，以获得 K 和 Ss 分布的一致解释，并系统地减少相关的不确定性。前期研究表明，HT数据本质上比单井抽油试验包含更多信息，联合解释方法在刻画非均质性方面优于传统数据分析方法。然而，最近的一项研究（例如，Berg 和 Illman，2011b）表明，HT 需要进一步研究和开发来对高度异质多孔介质进行成像。

Hydraulic tomography (HT) is rapidly emerging as a new field technology to image the subsurface heterogeneity for both hydraulic conductivity (K) and specific storage (Ss). In particular, HT involves (1) conducting sequential aquifer hydraulic tests over a well network and (2) jointly analyzing the complete data set to obtain a consistent interpretation of the K and Ss distributions and to systematically reduce the associated uncertainties. Prior research has shown that HT data inherently contain more information than single well pumping tests and the joint interpretation method is superior to conventional data analysis methods in delineating the heterogeneities. However, a recent study (e.g., Berg and Illman, 2011b) suggests that HT requires further research and development to image highly heterogeneous porous media.
