New Method for Effectiveness Evaluation of Vuggy Reservoir

Several methods for quantitatively effectiveness evaluating of carbonate vuggy are discussed.Based on the micro-and macro-pore structure and the analyses of influences on reservoir production,a new method was proposed.In addition to general macroscopic porosity parameter,this method also considers some microscopic pore structure parameters(displacement pressure and average pore throat radius)and the reservoir development degree in vertical.It made up for porosity and increased the accuracy of evaluating reservoir effectiveness.It has been applied to Tazhong and Lungu zones of Tarim Basin,and good effects have been obtained.
