基于数域上的模糊模式识别在测井曲线分层中的应用

６０年代以来提出的多种测井曲线计算机自动分层方法均采用一条曲线划分地层。此文提出的数域上的模糊式识别法是一种多条曲线的自动分层方法。其方法是构造一个在数域上的贴近度公式，采用贴近度准则，综合利用多条曲线所具有的测井信息，给出一个统一的分层点。应用结果表明，该方法比传统方法精度高，速度快，运算量小。

Application of Fuzzy Identification Method Based on Number Field to Zoning with Logs.

Various computerized automatic zonation methods proposed since 1960s make use of only one log curve. A kind of fuzzy identification method based on number field is proposed in this paper, which makes use of a number of logs for zoning. A formula of similiarity degree in number field is formed in this method. By the rule of similiarity degree, logging information obtained from multiple logs is integrated to provide a unified zoning point. The application result shows that this method is faster, more accurate and has less quantity of calculation than the traditional methods.
