摘　　要：针对20%孔隙度饱和水的石灰岩地层,应用蒙特卡罗方法模拟了探测器计数在地层径向、纵向和空间上的变化,进而模拟得到不同源距处探测器计数随地层径向深度变化的关系曲线。这些可为优化仪器设计提供源距参数。By the Monte Carlo method, the changes of detector tallies in formation radial, longitudinal direction and space has been simulated for the formation of water saturated limestone with 20% porosity. Thus, the relationship between detector tallies and formation radial depth is gained. The study can provides spacing parameters for tool designing.
