Abstract
一种元素俘获能谱测井的伽马能谱解谱方法及装置,解谱方法首先对元素俘获能谱测井仪获取的数据进行预处理,然后构建主元素群和辅助元素群,进而在主、辅助元素群构建的基础上利用最小二乘法进行解谱,最后根据最小二乘法解谱获得的各元素产额进行能谱重构,将测量的伽马能谱与重构的伽马能谱对比进行误差控制,相应地,解谱装置包括数据采集及主要元素类型确定模块(101)、元素俘获伽马能谱测井数据预处理模块(102)、主元素群和辅助元素群构建模块(103)、基于元素群的最小二乘法解谱模块(104)以及伽马能谱重构及误差控制模块(105)。元素俘获能谱测井的伽马能谱解谱方法及装置均具有高精度、可操作性强的优点,对不同类型储层均具有较好的普适性,同时为其他类型仪器的中子伽马能谱数据的处理提供了重要的参考和借鉴意义。
