摘要
Based on field investigation and data of borehole pumping test, the structure, hydrogeology and their controls to the coalbed methane （CBM） preservation in the eastern margin of the Ordos Basin were discussed. The results showed that the compression faults and folds with nearly south-north direction develop well in the basin margins, and the tectonic deformation weaken gradually towards the center of the basin, which indicates the structure both in the margin and center of the basin is all conducive to the CBM preservation.
