模式识别在测井曲线地层对比中的应用

APPLICAT1ON OF PATTERN RECONGNITION TO STRATIGRAPHIC CORRELATIAN OF WELL-LOGGING CURVE

采用模式识别与动态规划中有序元素最佳匹配用结合的方法，在完成单井分层解释的基础上，根据测井曲线进行地层对比。模式识别与有序元素最佳匹配用结合的方法进行地层对比，既能研究不同地层的相似程度，同时又能确定对比井之一的地层因断层或尖灭等原因造成的缺失。按照这种方法编制软件对实际２口井的测井资料进行处理，证明是可行的。

Stratigraphic correlation has been performed by combining the pattern recognition withthe optimal matching of ordinal elements in dynamic problems and based on the single-strati-flto well-logging data interpretation. The combination of pattern recognition with ordinal el-ement optimal matching method to carry out stratigraphic correlation can not only analysethe degree of similarity in different layers,but can also determine the absent layer caused byfauIts, stratigraphic pinch-out and other complicated factors.According to the principle,Wehave made a program and processed the well-logging data of 2 wells. The results proved tobefeasible.
