Abstract
本申请公开了一种含氢指数校正方法、装置及计算设备。方法包括：获取标准环境参数下含氢指数与热中子计数比的第一函数关系；针对任一环境参数的任一参数值，利用中子测井正演模型模拟获取在不同孔隙度值下的热中子计数比值，环境参数包括矿物类型和 / 或流体类型；根据该环境参数该参数值的热中子计数比值及第一函数关系计算含氢指数值，根据孔隙度值以及含氢指数值生成该环境参数的该参数值下校正量与含氢指数的第二函数关系；利用第二函数关系对实际环境参数的含氢指数测量值进行校正。本方案能够对不同矿物类型和 / 或不同流体类型的复杂环境进行含氢指数校正，提升含氢指数校正的适用范围，提高含氢指数表征地层孔隙度的精度。
