煤体内部裂隙和流体通道分析的核磁共振成像方法研究
A method of nuclear magnetic resonance imaging analyzed in the crack and fluid pass way of coal body
【摘要】 将水饱和煤样置于核磁共振仪中,利用核磁共振成像技术获取水饱和煤样的核磁共振图像。应用数值软件中的图像处理函数对共振图像进行处理分析,观察研究煤样的主裂隙及水在煤样流体通道中的流动情况。
【Abstract】 Coal sample saturated by water is put in the nuclear magnetic resonance instrument and the nuclear magnetic resonance ima-ges of the coal sample are gained by nuclear magnetic resonance imaging technology.The images are carried on the processing analysiswith the imagery processing function in numerical simulation software to observe the main crevasse of the sample and the flow of waterin the fluid pass way of the sample.
