The problem on injecting a solvent into a porous medium 
clogged up because of the deposition of a solid phase (paraffins, bitumens) 
is considered. Within the framework of the schemes of plane-one-dimensional 
and radial-symmetric filtration, self-similar solutions are obtained 
that describe the distributions of density and velocity as well as 
evolution of a cleaned zone. Numerical evaluations are presented for 
a quantity which determines the laws of motion of the cleaned zone 
boundary as function of the parameters of the stratum and the injected 
solvent.
