Multilevel Fuzzy Analytical Approach on Evaluating the Effects of Reservoir Profile Control Measures
油田调剖效果的多层次模糊分析方法

Because the single factor appraisal method for evaluation the effect of profile control measures is not integrated,a comprehensive fuzzy appraisal,which combined several indices including production performance data,water flooding curves,monitoring data and economy assessment,is used to evaluate the effects of the profile control measures.The analytic hierarchy process is applied to determine the weighing coefficient of these indices.The result of the evaluation is classified according to the optimal partition method and analysis shows that effects of 32 times of profile control treatment in Dongxin oil field should be sorted into 5 classes to obtain a minimum error and a clear classification.This result shows that the comprehensive fuzzy appraisal method,which avoids the unilateralism of single factor evaluation,reflects the effects of profile control measures objectively and makes the appraisal systematical and quantitative.
