| 摘 要： | 提出将注水试验视为"反抽水"的假设,尝试将抽水试验的配线法运用到注水试验的数据处理中,在渗透性差、抽水量小等开展抽水试验困难的砂岩铀矿床进行注水试验可获取较为准确的水文地质参数。以新疆某铀矿床注水试验为例,将"反抽水"配线法和水位恢复法二者的计算结果进行对比,结果表明,利用"反抽水"假设法计算主含矿含水层的水文地质参数是可行的。

| Abstract: | A hypothesis of regarding injecting test as "anti-pumping" test is presented,and pumping test’s "match line method" is used to process data of injecting test.Accurate hydrogeologic parameters can be obtained by injecting test in the sandstone uranium deposits with low permeability and small pumping volume.Taking injecting test in a uranium deposit of Xinjiang for example,the hydrogeolo-gic parameters of main ore-bearing aquifer were calculated by using the "anti-pumping" hypothesis.Results calculated by the "anti-pumping" hypothesis were compared with results calculated by water level recovery method.The results show that it is feasible to use "anti-pumping" hypothesis to calculate the hydrogeologic parameters of main ore-bearing aquifer. |
