Abstract:

The drilling core is precious geological material for the study of hydrocarbon zone and hydrocarbon reservoir. Core
image is the surface image of drilling core by using high resolution core image acquisition instruments. When image resolution
is high enough，the sediment characteristics in core image can be clearly recognized. The paper introduces the application of
core image in sandy conglomerate core diameter，area and psephicity calculation，and so on. It is expected to provide some
help for exploration of subtle reservoirs gradually deepen.

Key words: drilling core, sandy conglomerate, core image, image recognition, quantitative description
