模糊信息处理方法在油气识别中的应用

Applied Research of Fuzzy Information Processing Methods in Distinguishing Oil-Gas Reservoir Strata

通过对模糊理论的研究,利用模糊信息处理方法完成对储集层的热解参数的处理,建立了凝析油气层、气层、油层、差油层、油水同层、含油水层、水层、干层等八类储集层模式的特性指标的隶属函数、模糊识别矩阵以及最优模糊聚类中心矩阵。通过实验验证,该方法具有较好的识别效果。

Through the study of fuzzy theory,the fuzzy information processing method is used to deal with the pyrolysis parameters of the reservoir in this paper. Membership functions of some characteristic indexes,a fuzzy recognition matrix and an optimal fuzzy cluster center matrix of condensate oil-gas stratum,gas stratum,oil stratum,lack-oil stratum,oil-water zone,water stratum containing oil,water zone and dry stratum are established.
