A Novel Well Productivity Model of Carbonate Reservoir Matrix Acidizing Considering Wormhole
摘要
Abstract
We studied the wormhole effect on the well productivity which conventional well productivity model of matrix acidizing in carbonate reservoir did not take into consideration. On the basis of the wormhole growth model in radial geometry and the equivalent permeability model,this paper established a new well productivity model considering wormhole. Based on the laboratory experiment data of carbonate core displacement by 15%HCl,we selected the optimal acid injection velocity and the optimal pore volume to breakthrough,and calculated the effective dominant wormhole length and diameter and equivalent permeability in post-stimulation area near wellbore. Then we calculated the well productivity,and compared it with the real productivity,and the result shows that when considering the wormhole,the new model is accurate and reliable. This research presents a new method to predict the well productivity for matrix acidizing in carbonate reservoir.关键词
