从显微CT技术基本原理角度,分析了显微CT技术在多孔介质孔隙结构及渗透机理研究中的应用价值,直观、精确、无损地对钻孔岩心进行透视扫描、定量分析,鉴别岩石性质、矿物成分、量化岩石中孔隙发育情况,动态地显示重建后的透视投影数据,清晰地呈现出岩心内部微观结构和储层中油气运移规律,直接获取岩心有关储层物理特征数据,并模拟出所称岩心的3维立体模型。该技术非常适用于油气勘探开发过程,直观储层性质的变化规律,必将在石油地质中发挥重要的作用,应加大该设备的引进与研究力度。
From the perspective of the basic principle of micro-CT, the application value of micro-CT in the study of pore structure and infiltration mechanism in porous media was analyzed. The drilling core was scanned visually and accurately and non-destructively, Mineral composition, quantify the pore development in rock, dynamically display the reconstructed perspective projection data, clearly show the microstructure inside the core and the laws of hydrocarbon migration in the reservoir, directly obtain the physical characteristics of the reservoir core data and simulate the A three-dimensional model of the core. The technology is very suitable for the process of oil and gas exploration and development, intuitive changes in the nature of reservoir nature, will certainly play an important role in petroleum geology, should increase the introduction of equipment and research efforts.
