摘　　要：在塔里木盆地碳酸盐岩储层实际评价工作基础上,结合近期大量发表文献,系统地总结当前碳酸盐岩储层渗透率研究新进展。基于孔隙结构是影响储层岩石渗透率的重要因素,首先论述应用2D/3D数字化成像技术定量地表征岩石孔隙结构;重点讨论将这些孔隙结构参数与储集岩类型的概念相结合,形成一种新的储集岩类型划分方法;接着综述了应用NMR和FMI测井及三维地震评价碳酸盐岩储层渗透率的研究新进展,进一步指出,综合2D/3D数字化成像技术、新储集岩类型划分方法、NMR和FMI测井及三维地震,将是一套新的碳酸盐岩储层渗透率评价思路。Permeability that measures the ability of a rock transmit fluids is the key reservoir parameter in reservoir characterization and prediction, which is of paramount importance in exploration and development of carbonate petroleum reservoirs. This article aims to summarize the current state of the art in research on carbonate rocks＇ permeability. Based on the fact that pore networks of reservoir rock primarily influence the intrinsic permeability, so, firstly, it discusses quantitative characterization of pore structure in sidewall plugs and/or drill cuttings by employing 2D/3D digital image analysis （DIA） technologies. As permeability is predominantly a function of rock type, it subsequently emphasizes an alternative method to determine reservoir rock types with the combination of those forenamed 2D/3D DIA parameters. Meanwhile, new progresses on the utilization of NMR, FMI logs and 3D seismic data to predict spatial distribution of reservoirs rocks＇ permeability are overviewed. Further, it is argued that a new approach integrating 2D/3D DIA technologies, new reservoir rock classification method and NMR, FMI logging and 3D seismic interpretation should be promoted extensively and treated as a critical part in carbonate reservoir characterization and prediction.
