NONSTATIONARY POROSITY AND DENSITY FIELDS AT THE STAGE OF WITHDRAWAL OF AN ACID SOLUTION FROM A CARBONATE STRATUM
The authors have considered the problem on concentration fi elds of hydrochloric acid with account taken of the chemical reaction as applied to the stage of withdrawal of the active solution from a carbonate stratum. Analytical expressions to determine the porosity of the carbonate skeleton and the density of the hydrochloric acid solution, which are applicable for engineering calculations, have been found with account of the preceding technological processes. The results of computational experiments on the process of acidic stimulation have been analyzed, and it has been shown that the obtained dependences can be used for calculations of cyclic stimulation of oil and gas reservoirs, which is implemented to enhance the oil recovery
