An asymptotic solution of the problem of a temperature 
field in carbonate-containing oil-gas beds exposed to the action of 
an acid is obtained. Expressions for the concentration fields of the 
acid and reaction products and the porosity and temperature in the 
zero and first approximation have been constructed. The space-time 
distributions of the temperature have been calculated, and the contribution 
of various physical processes has been analyzed.
