应用ECS测井资料丰富岩性识别图版信息

Application of ECS Logging Data Increases Crossplot Informations in Identifying Volcanic Lithology

在火山岩储层研究中,岩性识别显得越来越重要。利用常规测井曲线识别岩性简单有效的方法是交会图版法。以松辽盆地北部深层火山岩为对象,利用岩心薄片和对应的ECS测井资料双向定名绘制了该区的岩性识别图版。薄片毕竟是有限的,利用其他井的ECS资料对未有薄片样点的图版区域进行划分,丰富了图版信息。

Litholoyical identification is becoming increasingly important in the study of volcanic rock reservoirs.Application of conventional well log in identification volcanic lithology is simple and effective well log crossplots,volcanic rocks of northern Songliao Basin are used as examples and the identifying volcanic lithological drawing bases are complied based on crossplots,at the same time using ECS log data to identify lithology.Thin slices is limited,the use of others well ECS information to classify the chart where is not containing thin slices.
