摘　　要：针对核磁共振(NMR)测井教学理论性强、原理抽象复杂等特点,设计了基于MATLABGUI的NMR双等待时间(TW)测井储层流体识别仿真实验,设计的MATLAB GUI交互界面包含地层T2谱模型构建、流体极化及双TW回波数据正演和回波数据处理等模块。通过在仿真实验中输入不同参数,模拟得到的地层T2谱模型、长短TW回波数据和处理结果将实时显示在图形界面,并对实际NMR测井资料进行了处理。该仿真实验操作简单,能将NMR双TW测井储层流体识别过程及结果直观地展示给学生,增强学生对该流体识别方法的理解,提高NMR测井教学效果。In view of the characteristics of nuclear magnetic resonance(NMR)logging teaching with strong theory content and abstract and complex principles,this paper designs a reservoir fluid identification simulation experiment of nuclear magnetic resonance(NMR)dual waiting time(TW)logging based on MATLAB GUI.The designed MATLAB GUI interactive interface includes the construction of formation T2 spectrum model,fluid polarization,dual TW echo data forward modeling and echo data processing modules.By entering different parameters in the simulation experiment,the simulated formation T2 spectrum model,long and short TW echo data and processing results can be displayed in real time in the graphical interface,and the actual NMR logging data are processed.The simulation experiment is simple to operate,which can visually display the reservoir fluid identification process and results of NMR dual TW logging to students,enhance students'understanding of the fluid identification method,and improve the teaching effect of NMR logging.
