摘要

The successful matrix stimulation of carbonate reservoirs requires that live acid penetrate past the formation damage. Effective acid penetration is facilitated either by transport through natural fractures or the formation of dissolution channels (wormholes) during the acidizing process. The optimal formation of wormholes and/or transport of live acid along natural fractures depends on the rate of reaction between the acid and the formation minerals, the rate of acid transport to the mineral surface, and the rate of acid convection along the wormhole and/or fracture. There are three prevailing theories in the literature that estimate the efficacy of acid stimulation treatmentsin carbonate formations. These theories predict the conditions at which wormhole formation occurs most efficiently and are based on the existence of: 1) an optimum injection rate at a transition between reaction-rate limited and fluid-loss limited regimes, 2) an optimum Peclet number, and 3) an optimum Damkoehler number.
