【摘要】 根据松辽盆地北部深层火成岩的岩心及录井资料 ,将该区火成岩划分为 6种类型 ,并对这 6种岩性的 11种测井数据进行统计分析 ,获得了对这 6种岩性的测井响应特征的认识。利用最大隶属原则 ,编程实现了火成岩地层岩性的自动识别。实际处理结果与岩心或录井岩性柱状图的对比表明 ,该方法对松辽盆地北部深层火成岩岩性划分具有较好的效果更多还原

【Abstract】 According to core and log data from deep igneous rocks in the northern Songliao Basin, the igneous rocks can be divided six classes. For each class 11 log data are used in the statistical analysis to extract the characteristics associated with different lithology. The lithologies of the igneous rock layer are automatically discriminated under the maximum membership. The comparison between the results thus obtained and the lithological column from cores or well logs shows that the method is good at lithology classification for deep igneous rocks in the area.更多还原
