摘　　要：使用测井数据对地震属性进行标定,寻求两类数据的一种线性的或非线性的定量函数关系,根据这种函数关系,可将地震属性转换为希望的储层物性。地震属性标定和储层物性转换使用着地质统计学方法。本文对现用的地质统计学方法做了系统介绍。这些方法包括多元统计分析、相关滤波技术、克里金预测技术、协克里金方法和利用相关学科知识实现参数的转换。The seismic attributes were calibrated to seek a linear or nonlinear quantitative function relation between twokinds of data by using logging data. According to the relation of the function, seismic attributes can be converted in-to desired reservoir physical property. The geologic statistics methods are used to make seismic attribute calibrationand reservoir physical property conversion. The geologic statistics methods being used are introduced systematicallyin this paper, which are including multivariate statistical analysis, correlation filtering technique, kriging prediction,co-kriging method and parameter conversion using correlation knowledge .
