将地电方法与动态导出的地质力学参数集成在尼日利亚 横河州部分地区预测含水层存储特性
摘要
性储存和重力排水进行储存和 / 或释放。含水层储存参数传统上是根据抽水试验数据确定的，在钻井之前，这
些数据很少可用。利用经验公式 S=3.0×10-6b，根据岩石岩性和含水层厚度估算承压含水层的储水量（S），但
S=Ssb 忽略了孔隙度和压缩性的影响。储量方程假设所有含水岩石具有恒定的比储量，尽管比储量直接取决于
岩石孔隙度，最重要的是，岩石颗粒的压缩性因岩性而异。在这项研究中，解释了 31 个位置的场电阻测量得
出的视电阻率数据，以推断地质电层岩性和厚度。为了确定岩石颗粒的压缩性以计算比储存量，使用解释的表
层岩石的平均密度来估算含水层深度的垂直应力。结果表明，岩石矿物颗粒压缩性在 7.915×10-7至9.235×10-5/
Pa 之间，孔隙度在 0.08 至 1.64 之间，风化覆盖层和砂岩孔隙度较高；比存储量在 8.32×10-6 至 1.80×10-3 之
间，存储量在 3.161×10-6 到 1.96×10-3。很明显，结果表明，岩石类型以及不同含水层的蓄水量会导致比蓄水
量的不同。
