摘要整理
医学计算机断层扫描（CT）技术在医疗诊断中广泛应用于人体病变检测。近年来，科研人员将该技术引入石油工业，用于检测油气储层岩石样品的孔隙连通性及微观结构特征。微CT扫描技术因其非破坏性和高分辨率的优势，在储层岩石表征和多相流驱替实验中的原位监测中获得广泛关注。结合数字岩心物理（DRP）理论，CT扫描图像可精确描述和模拟岩样的孔隙结构。本综述系统阐述了微CT和医学CT扫描在油气工业中的应用现状，讨论了DRP与现代成像技术的最新进展，并通过实验和数值模拟相结合的方式进行了深入分析。DRP与CT扫描的耦合应用为孔隙网络模型的建立提供了新思路。该技术使得流体在多孔介质中的流动行为可视化成为可能，能够实时监测流体在岩心样品中的运动过程。本综述为油气工业中应用图像技术的新研究领域提供了系统总结，有助于相关研究人员快速掌握该领域的核心技术和应用方向。
