摘要: 本文把油气藏分类问题归结为模式识别问题,然后应用模糊模式识别技术,以油藏烃类体系的化学组成为数据特征,采用模糊统计试脸法确定类型模式的隶属函数,建二了油藏类型识别的模糊数学模型,从而较精确地定份描述了诸如油藏、气藏、凝析气藏等概念之间界限不分明的现象.并用实例作了检脸。

关键词: 油藏类型 模式识别 隶属函数 识别准则 隶属度

Abstract: In thds paper, the problem of classifying oil/gas reservoirs is proposed
as that of pattern recognition.Then,a fuzzy mathematical model for reco-
gnizing oil/gas reservoir types is designed based on fuzzy pattern recognition
technique., And a fuzzy statistical test method is applied to set up subordi-
nate functions of reservoir type patterns, Practice shows that it is a good
mathematical model.
