Models of near wellbore region acidizing at pressures below the parting pressure of formation are constructed: one-dimensional model of a wormhole and stochastic model of dissolution structure. In one-dimensional case in wormhole model it is supposed, that the growth direction of dissolution structure is known, and the axis of model is the axis of a wormhole. Results of wormhole modeling were compared to experimental data of one of Russian oil Fields. In two-dimensional case it is impossible to predict growth direction as the dissolution process has stochastic nature. Therefore, the dissolution structure is considered as fractal. Stochastic model is based on model of dielectric-breakdown. On models various characteristics of dissolution structures depending on Damkohler number defined as ratio of convection time to reaction time and Peclet number defined as ratio of diffusion time to convection time were investigated, also acidizing optimum technological parameters were investigated.
