刘辛，吴宏春，岳爱忠，等．中子┐中子测井数值模拟集成系统．测井技术，１９９８，２２（４）：２８７～２９０在二维居中和三维偏心的中子－中子测井数值模拟软件包ＮＮＬＳＰ和ＦＥＭ３Ｄ的基础上开发了中子测井数值模拟集成系统ＮＮＬＴＣ。该系统采用了ＷＩＮＤＯＷＳ用户界面技术和独立模块结构，在保留原有软件包计算精度高、速度快等优点的基础上，又包括了仪器划分、模型井模拟、居中响应计算、偏心响应计算、校正图版制作和多环境自动校正等功能。本文介绍了ＮＮＬＴＣ的设计思想，实现过程以及实际应用。
Liu Xin, Wu Hongchun, Yue Aizhong, et al. Neutron ┐ neutron logging numerical simulation integrated system Well Logging Technology, 1998,22 (4): 287 ~ 290 Based on NNLSP and FEM3D, two-dimensional central and three-dimensional eccentric neutron-neutron logging numerical simulation software packages NNLTC . The system uses WINDOWS user interface technology and independent module structure, while retaining the advantages of high accuracy and high speed of the original software package, it also includes instrument division, model well simulation, centering response calculation, eccentricity response calculation and correction Plate making and multi-environment automatic calibration and other functions. This article describes the NNLTC design thinking, implementation process and practical application.
