<正> This paper seeks for the line source and cylindrical planesource solutions of unsteady axisymmetrical two-dimensionalflow through infinite and finite reservoirs with triple po-rosity.They not only reveal the essential characteristicsof fractured reservoirs but also generalize and develop theexisting primal results of homogeneous and porous media.Ref.[1]gives the line source solution of unsteady axi-symmetrical two-dimensional flow in infinite reservoir withdouble porosity;in this paper we study the problem of flowthrough triple porous media.
