摘      要：Spherical symmetry convective-dispersive transport of a tracer contamination from continue and slug injection well in semi-infinite porous media has been studied. The analytical solution has been obtained by analytical inversion. The early time approximate solution was given. These solutions were compared and the characteristics of concentration distribution and change were investigated. The results show that in early time and late time the approximate solution is of significance.
