一种通用的岩心核磁共振实验数据分析软件设计与实现

DESIGN AND IMPLEMENTATION OF A UNIVERSAL CORE NMR EXPERIMENTAL DATA ANALYSIS SOFTWARE

岩心核磁共振实验中,原始采集数据的处理与分析非常关键,但各厂家核磁共振仪器提供的数据处理配套软件的反演方法、参数均不相同,使得同样的岩心测量得到的回波信息无法进行对比分析。研发一套通用的岩心核磁共振实验数据分析软件,基于统一的数据存储模式、统一的快速高分辨反演算法,允许设置不同反演参数和岩心分析参数,进行岩心核磁数据的反演和参数计算,实现所有仪器测量回波数据的统一处理和分析。目前软件支持NIUMAG公司、OXFORD公司、Magritek公司和CoreSpec-1000型仪器测量得到的原始数据,处理结果精确,具有操作简单、方便扩展的特点。

In the core Nuclear magnetic resonance(NMR)experiment,the processing and analysis of original collected data is very critical.However,the inversion methods and parameters of the data processing software provided by various NMR instruments manufacturers are different,which make it incapable of comparing and analyzing the echo information from the same core measurements.Thus,we developed a universal core NMR experimental data analysis software.It was based on the unified data storage model and unified fast and high-resolution inversion algorithm.The inversion and parameter calculation of core nuclear magnetic data were carried out by setting different inversion parameters and core analysis parameters,which realized the unified processing and analysis of echo data from all instrument measurement.At present,the software supports the original data measured by NIUMAG,OXFORD,Magritek and CoreSpec-1000 instruments.The processing results are accurate with simple operation method and convenient expansion.
