Paper Abstract

Hylogger hyperspectral core scanning system is used to detailed scan shale gas drilling cores, obtaining visible-near infrared (spectral range 380nm-1100nm), short-wave infrared (spectral range 1100nm-2500nm), thermal infrared (spectral range 6000-14500nm) spectral curves and high-definition core images. Based on the analysis of mineral covalent bond vibrations differences which is generated by wavelength discrepancies to extract the mineral information; Such as Hydrocarbon quantity、carbonate minerals、silicate minerals and iron oxides. Form the changes of those minerals assemblage we could deduce the information of diagenetic temperature and thermal maturity which have instruction significance for oil and gas exploration, meanwhile, combining with core image color, texture, contrast, brightness information the lithology can be quickly identified and the sedimentary environment can be inferred too. Integrate the information can provides a strong basis for the determination of favorable areas for hydrocarbon generation.
