Application of NMR in the Study of Shale Gas Reservoir

Abstract:

Shale characteristic is very important in the exploitation. Using NMR determine the pore distribution of shale, it is found that the pore radii of shale samples is mainly between 3-10nm, which is in accordance with the results of mercury injection. NMR is also applied in the determination of movable fluid of shale, gas saturation of the measured 14 samples is mainly between 12% and 28.1%, no relationship is found between gas saturation and porosity or permeability.
