摘要: 针对火山岩裂缝-孔隙型复杂孔隙结构储层,根据辽河盆地东部凹陷火山岩的地质特点,从岩矿分析入手,深入研究火山岩的岩石物理特征,阐明了火山岩测井评价机理,并建立了辽河盆地东部凹陷火山岩岩性识别测井评价方法。用多种交会图法定量识别火山岩岩性方面开展了研究工作,总结出适合本地区特点的、可操作性强的火山岩岩性识别测井评价方法。Abstract: Aiming at conquering the difficulty in evaluation of fractured reservoir of volcanic rocks, the authors began from mineralogy to study the rock composite and its physical character on the well logs, and built the methods of lithology log evaluation in volcanic rock of middle segment in easten sag of Liaohe basin. This article mainly referred to recognize and evaluate the lithology with well logs and numerable logplots.The methods had been built and will be used.
