碳酸盐岩储层非均质发育裂缝和溶蚀孔洞,具有更复杂的空隙空间结构与极强的各向异性,使得碳酸盐岩储层的渗透率评价技术成为碳酸盐岩测井评价技术的难题之一。目前评价碳酸盐岩储层渗透率主要利用岩心分析渗透率、常规测井渗透率、斯通利波渗透率、核磁共振渗透率和试井渗透率等。通过研究这些不同方法的适应性和应用效果,筛选出最适合碳酸盐岩储层渗透率评价方法。
The heterogeneous developmental fractures and dissolved pores in carbonate reservoirs have more complicated spatial structure and strong anisotropy, making the evaluation of permeability of carbonate reservoirs a carbonate well logging evaluation One of the technical problems. At present, the evaluation of permeability of carbonate reservoirs mainly uses core analysis permeability, conventional well permeability, Stoneley permeability, NMR permeability and well test permeability. By studying the adaptability and application effects of these different methods, the most suitable method for evaluating permeability of carbonate reservoirs is selected.
