裂缝性碳酸盐岩是世界上最重要的油气藏储层类型之一,其渗流机理一直是石油工程的研究难点和热点.随着油气勘探开发的不断深入,许多深层海相裂缝性碳酸盐岩油气藏被发现,现有理论已无法准确表征流体流动规律,亟待进一步发展和完善.基于对现有理论和方法的广泛调研,系统回顾了裂缝性碳酸盐岩油气藏裂缝渗流能力表征、不同介质间流体交换机制以及渗流数学模型等方面,展望了此类油气藏渗流理论今后的发展和研究方向.本文分析结果可以为国内外类似油气藏的高效开发起到指导和借鉴作用.
Fractured carbonate rock is one of the most important oil and gas reservoirs in the world, and its seepage mechanism has been a research hotspot and a hot spot in petroleum engineering.With the continuous deepening of oil and gas exploration and development, many deep marine fractured carbonates Salt rock reservoirs have been found, the existing theories can not accurately characterize the law of fluid flow and need to be further developed and perfected.Based on the extensive research on existing theories and methods, the authors systematically reviews the characterization of fracture seepage ability of fractured carbonate reservoirs , The fluid exchange mechanism between different media and the seepage mathematical model, the future development and research direction of such seepage theory of oil and gas reservoirs are prospected.The results of this paper can be used as guidance and reference for the efficient development of similar oil and gas reservoirs at home and abroad.
