摘要
根据三塘湖盆地研究区域火山岩岩性的分类,利用常规测井曲线交会图、成像测井和ECS (元素俘获谱)测井技术进行火山岩岩性识别。在求准岩性的基础上,利用混合骨架理论求取测井解释孔隙度值,进而计算含水饱和度等储层参数。从重点井的薄片鉴定结果及其岩心分析资料对比可以看出,该研究所提出的岩性识别和孔隙度的计算方法在火山岩储层评价中是行之有效的。
According to the lithology classification of volcanic rock in the research area of Santanghu basin, the lava lithology can be distinguished using cross plot of the normal well logging curves, imaging well logging and ECS （elemental capture spectroscopy logging）. Based on the lithology to be identified rightly, this study uses the mixed matrix theory to acquire the logging interpreted porosity so as to calculate the water saturation and other reservoir＇ s parameters. The contrastive result of rock slice identification and core analysis of key wells proved that the methods of lithology identification and porosity calculation can be used effectively in lava reservoir evaluation.
