摘　　要：将静储量研究与三维可视化建模相结合,引入储层地质建模的Petrel软件来定量化地计算煤系含水层的静储量,以鸳鸯湖矿区红柳煤矿七里镇砂岩含水层为例,通过分层建立七里镇砂岩的构造层面模型;结合声波时差测井数据与实验测试数据,计算出七里镇砂岩的孔隙度,根据随机模拟的方法,建立七里镇砂岩的孔隙度模型;最后以Petrel软件特有的储量计算功能计算出七里镇砂岩的静储量为42.598 km3。Petrel software which used for reservoir geologic modeling was introduced to quantitatively calculate the static reserves of coal-bearing aquifers. Taking the hongliu coal mine of yuanyanghu mining area as an example, based on the hierarchical data of qilizhen sandstone, the tectonic stratigraphic model of Qilizhen sandstone is established. Based on the data of acoustic time difference of logging data and the experimental data, the porosity of qilizhen sandstone is calculated. According to the method of stochastic simulation, the porosity model of qilizhen sandstone is established. Finally, the static reserve of qilizhen sandstone is 42.598 km^3 which calculated by the Petrel＇s unique calculation function.
