松辽盆地兴城地区营城组火山岩岩性的测井识别方法

Logging identification methods of vocanic rocks of Yingcheng Formation in Xingcheng area,Songliao Basin

综合岩心、薄片、扫描电镜、地球化学等多种分析测试手段,对研究区火山岩岩石类型进行了划分。以各种岩性测井为基础,分析不同岩性在各种测井曲线或成像图上的响应特征,进而应用交会图、聚类分析及成像测井等手段建立岩性识别模式,有效地识别研究区火山岩不同岩性,总结出适合研究区火山岩岩性测井识别方法。实践证明,应用效果较好。

The volcanic rock types in the study area have been classified by means of core,thin slice,scanning electron microscopy and geochemical analysis.Based on a variety of lithologic logging and analysis of the response characteristics of different lithology in a variety of well logs or imaging diagrams,lithology recognition model has been established by the application of intersection diagrams,cluster analysis and logging imaging.By adopting this model,the effects of which is proved effectual,an effective identification of different lithology of volcanic rocks in study area has become available,furthermore,logging identification methods of the volcanic lithology practicable in the study area has also been concluded.
