MORSE-CG程序三维基准中子多孔隙度测井计算

MORSE-CG CODE THREE-DIMENSION CALCULATIONOF THE BENCHMARK NEUTRON POROSITYWELL-LOGGING

用蒙特卡罗方法计算三维多孔隙度测井问题是一种比较有效的方法。本文给出增加了重新启动功能的MORSE-CG多功能蒙特卡罗程序计算孔隙度分别为1.0％和20.0％的基准中子测井问题的计算结果,以及其与MCNP和McDNL计算结果和计算时间的比较。比较显示三者在相同误差范围内的结果是一致的。

It is a valid method by using the Monte Carlo method to calculate three-dimensional porosity we 11-logging problems. This paper gives out the calculated results of the benchmark neutron well-logging problems with porosity 1% and 20% from the MORSE-CG code which the restart capability have been added into it, and thd comparison of it with MCNP and McDNL results and computing time. Results indicate that the three cokes give the same results within calculated standard deviations.
