Abstract
Interaction of acid with carbonate rocks is the basis for the processes of increasing productivity of producing wells and intensification of oil production from carbonate reservoirs. Dissolution of carbonates under conditions of filtration of acid solution through porous medium is determined by competition of chemical reaction processes and convective transfer of acid. Research on these competing processes is carried out in two main setups: a rotating carbonate disk washed by acid flow and an acid solution filtration setup through carbonate reservoir samples. The paper presents the results of such research with discussion of results and discussion of the reaction kinetics parameters on a sample of a particular field. The values of diffusion and reaction kinetics, critical rate of wormhole formation in porous medium at different concentrations of hydrochloric acid have been calculated. The values of the main dimensionless similarity complexes: Damköhler and Peckle numbers and acid solubility were estimated.
