摘要
选择伽马—伽马方法是煤田测井近几年发展起来的一种新方法,有必要对该方法进行深入探讨使之成为有意义的定量参数。本文从方法响应与原子序的关系、有效原子序数等方法原理入手,阐述了密度干扰剔除、室内刻度及野外刻度方法。分析表明,该法是受密度干扰的原子响应;系列模块刻度法可剔除密度干扰,建立Pe及U值的响应方程;经现场简易模块刻度对资料归一处理后,在一定条件下可进行煤灰定量解释。
The article explains methods of density disturbance rejection,laboratory graduation and field graduation starting from technique principle of relationship between gamma-gamma response and atomic number,effective atomic number,and so on.It is clear by analysising that this method is a atomic number response disturbed by density.Series modular graduation technique can reject the density disturbance and set up response of Pe value and U value.After data are normalized by site simple modular graduation,it can do quantity interpretation of coal ash contains on certain condition.
