| 摘 要： | 针对鄂尔多斯营盘壕井田的水文地质试验资料少,难以进行有效的富水性评价的问题,本文通过研究声波测井数据与有效孔隙度的相关关系,分析有效孔隙度在平面上的展布,依据地质情况选择含水层厚度和有效孔隙度两个指标构成评价体系,运用熵权法建立砂岩含水层富水性预测模型。通过抽水试验钻孔对砂岩富水性的验证,其结果与富水性的预测结果相符,且富水性预测结果符合水文地质试验数据的验证。结果说明该模型简单可靠,实用价值较高,有效地实现了研究区域砂岩含水层的富水性分区,为含水层富水性评价工作提供了新的方法。

| Abstract: | Aiming at solving the problem of the lack of hydrogeological test data in Yingpanhao mine field in Ordos, and it is difficult to evaluate water yield property effectively. This paper took logging and experimental data to predict the distribution of effective porosity of the aquifer on the plane. The entropy weight method and histogram statistic were used to build the two-indicator prediction model of water yield zone containing thickness and effective porosity. The model was verified by pumping test and the actual data have shown that the prediction model of the water yield zone is reasonable. It provides a new method for the evaluation of water yield property of aquifer. |
