Application analysis of shale gas core hyperspectral in weican-1 well

Hylogger core scanning system is used to detailed scan shale gas drilling cores, obtaining visible-near infrared (spectral range 380nm-1100nm),short-wave 1100nm-2500nm) spectral curves and high-definition images. Taking Well weican 1 in the West Taikang Uplift South China North Basin as an example, based on analysis of clay mineral types target layer, it judged be alkaline deposit environment rich iron magnesium with a temperature about130°C. Combined information image, layer divided,mud developed, cumulative thickness exceeds 400m, maximum single reaches 38m, at same time, hydrocarbon absorption characteristics section are obvious, shows good prospect for region.
