MODELING OF ACID TREATMENTS OF CARBONATE RESERVOIRS BASED ON FILTRATION-KINETIC STUDIES
Annotation. The article presents a methodology for designing acid treatments in the bottomhole zone of wells producing from carbonate reservoirs. The approach is based on the integration of results from filtration experiments, kinetic studies, and empirical modeling. Particular attention is paid to analyzing the influence of pore space heterogeneity and water cut on the formation of dissolution channels. A criteria-based approach is proposed for determining the optimal parameters for injecting acid compositions. The obtained results demonstrate the possibility of increasing the technological efficiency of treatments while simultaneously reducing the proportion of ineffective operations.
Keywords: acid treatment, carbonate reservoir, bottomhole zone, filtration, reaction kinetics, water cut, permeability, modeling.
