Development of a numerical model of the near borehole zone of a fractured-carbonate reservoir that accounts of the fractures permeability changes under the impact of mechanical effects during water injection and varying effective stresses
A model that changes the fractures width and permeability in a fractured carbonate reservoir under the influence of the injected water for various values of effective stresses is developed. A method is proposed for modeling the near borehole zone of an injection well, based on the finite element method, that accounts of the change in the fracture systems width and permeability under the influence of mechanical-chemical effects. The dynamics of the change in the well injectivity and the near borehole zone permeability under the influence of the injected water is shown.
