| Abstract: | The imaging mechanism and application in coal bed methane are presented.It is indicated that the permeability of coal seams,as an important parameter that shows the transport rule of coal bed methane,has favorable relativity with the NMRI permeability.The calculation means of NMRI permeability is put forward.The results show that the quantitative analysis and real-time observation of the storage and transport of coal bed methane by NMRI are more effective and accurate.So NMRI research on the storage and transport of coal bed methane supplies new means and approach to increase the recovery ratio of coal bed methane,which will play an important role in practice. |
