Using “Umbrella Deconstruction & Energy Dispersive Spectrometer (UD-EDS)” technique to quantify the anisotropic elements distribution of "Chang 7" shale and its significance

This study utilizes the experimental technique named “Umbrella Deconstruction & Energy Dispersive Spectrometer (UD-EDS)” method to quantify the anisotropic element distribution of shale which has been proved significant in the stimulation of shale. Direct quantification of anisotropic distribution of element in shale from the Triassic Yanchang formation in the HJS” district was carried out to ensure both observational resolution and sample...
