摘要: 油田钻探取芯所获得岩芯是研究油气田和研究油气层最直观、最宝贵的地质实物资料,岩芯图像是利用高分
辨率岩芯图像采集仪对岩芯实物资料的外表面或剖切面进行光学扫描形成的表面特征图像,在图像分辨率足够高的
条件下,岩芯图像上的沉积物特征非常明显。介绍了岩芯图像在砂砾岩岩芯结构描述和砾石的砾径、面积、磨圆度等
参数计算中的应用,期望对正在逐步深化的隐蔽油气勘探提供一些帮助。

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
