四川是碳酸盐岩油气储集层非常发育的地区,前寒武系、二迭系、三达系及侏罗系是著名的储量丰富,产能巨大的碳酸盐岩油气储集层系。近年又在石炭系中发现了高产碳酸盐岩气藏。四川碳酸盐岩储集层的研究,早已随着石油工业,特别是天然气工业的发展广泛开展。但是,常规的孔、渗物性分析及岩石薄片研究,长期不能顺利解释油气生产的地质特征及有效地指导勘探与开发。究竟是什么主要因素控制着储层产能高低?孔隙与裂缝之间有什么主要关系?孔隙与裂缝在控制储能及产能中究竟如何起作用?是
Sichuan is a well-developed carbonate reservoir. The Precambrian, Permian, Sanda and Jurassic formations are well-known reserves of abundant carbonate reservoirs with high productivity. In recent years, high-yield carbonate reservoirs have also been found in the Carboniferous. The research on carbonate reservoirs in Sichuan has long been carried out with the development of petroleum industry, especially natural gas industry. However, conventional pore and permeability analysis and rock thin research have long failed to explain the geological features of oil and gas production and effectively guide exploration and development. What are the main factors that control the level of reservoir productivity? What are the main relationships between porosity and fracture? How do pores and cracks play a role in controlling energy storage and production capacity?
