浅析显微CT技术在油气储层研究中的应用

APPLICATION OF MICROSCOPIC CT IN OIL-GAS RESERVOIR STUDY

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。

This paper, from the principle of microscopic CT technology, analyzes its application in porous structure and penetration mechanism, which can precisely, directly, harmless, perspectively scan cores, quantitatively analyze and identify rocks, minerals, and display porosity, dynamically show a reconstructed perspective projection data, and clearly reflect the internal microscopic texture and oil-gas migration rule in reservoir, and directly acquire reservoir physical data, and establish a 3D model of the rock. This technology works well in oil-gas exploration, and directly shows the reservoir property, which will surely play a key role in petroleum geology. China shall intensify study on and import this kind of equipment.
