Abstract: 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...
