深井灌注废液在深部含水层中运移的数值模拟

Numerical simulation of injected waste transport in the deep aquifer

根据山东东营某地的地质、水文地质资料,模拟了在该地区建设灌注井时灌注废液在深部含水层中的运移。数学模型考虑了流体密度、粘滞性以及灌注层孔隙度随压力或浓度的变化。模拟计算采用美国深井灌注项目中广泛应用的SWIFT数值模拟软件,讨论了模型中主要水文地质参数变化对计算结果的影响。模拟结果对灌注井位置的选择、调查区域的确定以及监测井的布置都有着很好的指导意义。

Based on the geological and hydrogeological data of a certain place in the city of Dongying,the numerical simulation of injected liquid waste transport in the deep aquifer is performed in the study,assuming that an injection well had been built there.The mathematical model established takes into account the variation in fluid density,viscosity and porosity with pressure or concentration.SWIFT,which has been widely used for numerical simulations in the underground injection projects in the USA,is employed in the study.This paper examined the impact on the simulation results when some changes were made to main hydrogeological parameters.The results is of an important guiding significance for the choice of the well location,the determination of the area of review,and the arrangement of the monitoring wells.
