Characterization of porosity in carbonate rocks is important in the oil and gas industry since a major hydrocarbons field is formed by this lithology and they have a complex media porous. In this context, this research presents a study of the pore space in limestones rocks by x-ray microtomography. Total porosity, type of porosity and pore size distribution were evaluated from 3D high resolution images. Results show that carbonate rocks has a complex pore space system with different pores types at the same facies.
在石油和天然气行业中，碳酸盐岩孔隙度的表征非常重要，因为主要的油气田是由这种岩性形成的，而且它们具有复杂的多孔介质。在此背景下，本研究通过X射线显微断层扫描对石灰岩中的孔隙空间进行了研究。从三维高分辨率图像中评估了总孔隙度、孔隙类型和孔径分布。结果表明，碳酸盐岩具有复杂的孔隙空间系统，在同一岩相中存在不同类型的孔隙。
