Effect of Isolated Fracture on the Carbonate Acidizing Process

Carbonate reservoirs are one of the most important fossil fuel sources, and acidizing stimulation is a practical technique for improving recovery carbonate reservoirs. In this study, improved two-scale continuum model, including representative elementary volume (REV) scale model upscaling used to study process with an isolated fracture. Based on comprehensive discussion presented effect physical parameters fracture results dissolution images, geometry, location, morphology. Results show that system still target stimulation. The provides limited contribution core porosity. permeability sample can be obviously increased only when penetrates through whole sample. existence reduces consumption acid solution achieve breakthrough. curve sensitive change length, aperture, position difference corresponding different rotation angles has not changed significantly clockwise anticlockwise groups.
