摘要:

碳酸盐岩气藏在世界范围内已经发现的气藏中占有重要地位。近年来中国的碳酸盐岩气藏勘探开发也呈现出快速发展的态势,特别是在塔里木、鄂尔多斯和四川盆地,碳酸盐岩气藏已经成为陆上开发有前景的气藏类型。碳酸盐岩气藏的开发不同于碎屑岩气藏,正确认识碳酸盐岩气藏的类型和开发特征对于增强碳酸盐岩气藏开发的理论性和系统性具有十分重要的意义。基于中国碳酸盐岩气藏开发的实践,按照"实用性、指导性和科学性"的划分原则将碳酸盐岩气藏分为缝洞型、礁滩型、岩溶风化壳型和层状白云岩型4种类型。缝洞型碳酸盐岩油气藏以多缝洞单元为特征;礁滩型碳酸盐岩气藏以多气-水单元为特征;岩溶风化壳型碳酸盐岩以发育不同规模尺度优劣储集体为特征;层状白云岩气藏以发育层状白云岩储层为特征。碳酸盐岩气藏类型划分和开发特征研究为全面认识碳酸盐岩气藏奠定了基础,同时为相同类型碳酸盐岩气藏的开发提供有效指导。

Abstract:

Carbonate gas reservoirs occupy an important proportion of all the gas reservoirs discovered in the world. In recent years, exploration and development of carbonate gas reservoirs in China have showed a rapid rising trend, especially in the Tarim, Erdos and Sichuan basins. Carbonate gas reservoirs have become one of the most promising areas for the China's onshore oil-gas exploration and development. The carbonate gas reservoir development is different from that of clastic gas reservoirs, so a precise understanding on type classification and development characteristics of carbonate gas reservoirs is very important to theoretical and systematic studies of carbonate gas reservoir development. Based on the development practice of carbonate gas reservoirs in China, carbonate gas reservoirs are divided into four types in accordance with principles of practicality, directivity and scientificity, which include fractured cavity, reef shoal, karstic weathering crust and bedded dolomite. These carbonate gas reservoirs are generally characterized by multi-fractured-cavity units for the fractured-cavity type, multiple gas-water units for the reef-shoal type, good or poor reservoirs with different size for the karstic weathering crust type and developed dolomite beddings for the bedded dolomite type, respectively. The study on type classification and development characteristics of carbonate gas reservoirs laid a foundation for a comprehensive understanding of carbonate gas reservoirs and could provide an effective guidance to the development of the same type carbonate gas reservoirs.

Key words: carbonate gas reservoir, gas reservoir type, type classification, classification principle, development characteristic
