摘要碳酸盐岩储层具有复杂的孔隙结构和储集空间，孔隙大小分布范围很大。孔结构呈双峰或三峰分布，并伴有明显的非阿尔奇现象。基于孔隙尺寸分类的双孔隙度和三孔隙度电导率模型与非阿尔奇行为具有较好的一致性。采用数字岩心技术对碳酸盐岩双孔隙电导率模型进行了验证。此外，进行了大量的岩石物理实验和数值模拟。通过适当分辨率的CT扫描，对碳酸盐岩样品分别建立了宏观和微观数字岩心，以表征不同孔隙。在此基础上，进一步应用叠加法构建了可同时表征不同孔隙的叠加数字岩心。定量分析和比较了基本结构参数对系统性能的影响。
AbstractCarbonate reservoirs have complicated pore structure and reserving space, and the pore size distribution ranges are very large. Pore structure distributions represent a bimodal or trimodal state, which is also accompanied with an obviously non-Archie phenomenon. Double- and triple-porosity conductivity models based on the classification of pore dimensions were of a good coincidence with the non-Archie behavior. We have adopted digital core technology to verify the carbonate double-porosity conductivity model. Also, many rock-physical experiments and numerical simulations were performed. Through CT scanning under appropriate resolutions, macro- and micropore digital cores, which could respectively characterize the different pores, were constructed for the carbonate samples. Then the superposition method was further applied to construct the superposition digital cores, which can characterize different pores simultaneously. To quantitatively analyze and compare the effect of basic structural paramete...
