摘要: 根据单井相分析的特点,提出了一种基于优先比的沉积相模糊模式识别方法,通过对相标志进行预处理选择了一系列用于相识别的数字特征,建立了湖泊三角洲不同微相单元的数值模式,并进行了实际应用.

Abstract: Based upon the features of facies analysis,a new method using fuzzy preference ratio forquantitative sedimentary facies analysis-faszy pattern recognition is presented.Through thepreprocessing of facies markers,some numerical characteristics for facies recognition are selected,and the numerical patterns of microfacies units composing delta in lakes are established.And a case of practical application is given.
