【摘要】 在分析了储层损害多源信息的特征后,构造了基于决策层融合与证据理论、针对储层损害诊断识别的信息融合数学模型,给出了决策层融合的实现算法。通过对储层水敏损害程度的诊断识别,融合模型从多方面将反映储层损害类型的多源信息进行综合分析和决策融合处理,系统地对储层损害类型进行了识别和特征判断,有效地提高了储层损害诊断的准确性和可靠性。更多还原

【Abstract】 A mathematical mergence model based on decision level data fusion and evidence theory was developed for formation damage diagnosis by analyzing the features of multiple source information of formation damages.The concrete algorithm of the data fusion in decision level was presented.By analyzing and diagnosing the water sensitivity of a reservior,the reservior information from multi-sources which reflects the formation damage types was processed comprehensively by the model,and the formation damage types were judged systemically.The accuracy and reliability of formation damage diagnosis can be effectively improved.更多还原
