摘要
作者在 MCNP的基础上 ,开发了中子测井 ,中子通量随空间、能量、时间分布蒙特卡罗(Monte Carlo)模拟软件包。对裸眼井、井眼里无下井仪器、水饱和灰岩地层、井眼注水 ,用该软件计算了沿井轴和沿井壁中子通量随能量、时间分布 ,以及沿井轴和沿井壁热中子和超热中子时间谱。即源距变化对中子通量随能量、时间分布和井轴与井壁热中子、超热中子时间谱的影响。
Based on MCNP, authors developed the software package of the Monte Carlo method to simulate the neutron flux distributions with the space, energy and time for neutron logging. For the following conditions: an open hole well, without logging instrument in bore hole, fresh water saturated limestone formation, injected fresh water in bore hole, the software package was used to compute the neutron flux distributions with the energy and time along bore hole axis and wall, and the time spectra of thermal neutron and the time spectra of epithermal neutron along bore hole axis and wall. The spacing influence of source distance variation on neutron flux distributions with the energy and time and the time spectra of thermal neutron and the time spectra of epithermal neutron along bore hole axis and wall were studied.
