摘要
测井分层和测井参数分布的模糊性，是川东石炭系黄龙组碳酸盐岩剖面测井沉积相判识中的困难所在。在引入隶属函数概念的基础上，根据模糊模式识别和模糊专家决策的机理，开发出适用于碳酸盐岩剖面测井沉积相的模糊判识系统。通过对三个井黄龙组沉积微相的判识表明，系统的平均正确判别率达８８５，具有良好的应用前景。
AbstractThe fuzzy characters of log layering and log parameter distritution are difficult problems in log-sedimentary facies recognition of carbonatite section of Carboniferous Huanglong Formation in East Sichuan.Based on the introduced conception of subordinate function,the fuzzy recognition system of log-sedimentary facies of carbonatite section is deveolped according to the principle of fuzzy recognition and fuzzy expert dicision.The results of three wells'recognition of the sedimentary microfacies of Huanglong Formation show that the rate of correct recognition of the system is up to 850/0,which brings it a bright application prospect.
