摘　　要：中国碳酸盐岩气藏主要分布在塔里木、四川和鄂尔多斯盆地,碳酸盐岩气藏开发面临着储层非均质性强、预测难度大、流体性质及分布复杂、单井产量差异大、稳产难度大等难题。立足于中国碳酸盐岩气藏的开发实践,可将中国碳酸盐岩气藏划分为:缝洞型、礁滩型、风化壳型以及层状白云岩型4种类型。不同类型碳酸盐岩气藏在储集空间、储层成因、开发特征等方面存在很大差异,气藏特征的差异导致不同类型碳酸盐岩气藏面临不同的开发难题。以中国目前正在开发的4个典型碳酸盐岩气藏为例研究不同类型气藏开发面临的问题,并在此基础上提出了典型气藏开发的解决对策,从而为不同类型碳酸盐岩气藏实现"规模建产、高效开发"提供技术支撑。Carbonate gas reservoirs in China are mainly distributed in the Tarim,Sichuan and Ordos Basin.It is facing many problems in developing them such as the strong heterogeneity of reservoirs,the great difficulty in prediction,and the complexity of fluid property and its distribution.Meanwhile,the difference of single well productivity is always very large and it is also very hard to keep their steady production for single well or the whole reservoir.Based on the development practices,carbonate gas reservoirs in China can be divided into four types,which include fractured vuggy,reef flat,weathering crust and layered dolomite carbonate gas field.Different types of carbonate gas reservoir have significant difference in reservoir space,reservoir genesis,and development character istic.These differences result that the development of different type of carbonate gas reservoir faces different problems.Taking four typical carbonate gas reservoirs as an example,this paper describes the problems faced by different types carbonate gas reservoir.Meanwhile,countermeasures are proposed in order to offer technical support to different carbonate gas reservoir.Finally,it can realize commercial productivity construction and high efficient development to different types of carbonate gas reservoir.
