摘要
开发一套核磁共振T_2(横向弛豫)弛豫仿真软件,考虑了不完全极化、扩散弛豫、信噪比等多种因素,完成岩心核磁共振实验及井下核磁共振测井的数值模拟。仿真软件由弛豫谱构造、模拟数据采集和回波拟合三个模块构成,采用实时图形化显示,可以同时模拟多种流体的T_2弛豫过程。该软件使用简单,结果精确,可在核磁共振反演算法、油气识别算法、岩心核磁实验参数优化等多个领域发挥作用。
We developed a set of nuclear magnetic resonance(NMR) T 2 relaxation simulation software. The software considered many factors, such as incomplete polarization, diffusion relaxation and signal-to-noise ratio. It could complete core NMR experiments and numerical simulation of NMR logging. The simulation software consisted of three modules: relaxation spectrum structure, analog data acquisition and echo fitting. It could simulate the T 2 relaxation process of various fluids simultaneously by using real-time graphical display. The software is simple in use and accurate in results. It can play an important role in many fields, such as NMR inversion algorithm, oil and gas identification algorithm, core NMR experiment parameter optimization and so on.
