ACCOUNT OF THE NUMBER OF STAGES AND OF CYCLICITY IN THE PROBLEM ON ACIDIC STIMULATION OF AN OIL-BEARING STRATUM

The problem on the change in the porosity when hydrochloric acid is injected into a carbonate-containing stratum has been solved in a cylindrical coordinate system. Expressions for calculating space-time dependences of the porosity and the density of the acid in the solution during the stimulation of carbonate-containing oil- and gasbearing strata have been obtained. The derived expressions take account of the preceding changes in the porosity and the acid density in the previous stages of stimulation
