摘要: 为了更准确地计算粘土束缚水含量和阳离子交换容量,依据现代核磁共振测井的基本原理,对孔隙度解释模型予以改进,提出了一种综合利用核磁共振测井和常规孔隙度测井资料计算粘土束缚水含量和阳离子交换容量的新方法。经过编程计算,并对实际井的测井曲线进行逐点解释处理,表明该方法效果良好,完全优于常规测井解释方法。

关键词: 粘土, 束缚水含量, 阳离子交换容量, 核磁共振测井, 常规孔隙度测井, 测井解释

Abstract: It is rather difficult to calculate clay bound water volume and cation exchange capacity from well log data. Based on modern nuclear magnetic resonance log (nmrl), porosity interpretation model is improved and ten a new approach to calculate the volume and capacity is pointed out by using cur data and con-
ventional log data together. And some programs are developed and some well’s log curves from real formation are processed and interpreted point by point. Its result is satisfactory and showed this method excels conventional log interpretation

Key words: clay, bound water volume, cation exchange capacity, nuclear magnetic resonance log, conventional porosity log, log interpretation
