摘要
气顶油藏油、气、水交错分布,驱动类型多,油气水运动非常复杂,利用气顶和边水能量使油气、油水界面均匀推进,在层间和平面不让过早地发生水窜和气窜,是开发控制和调整的核心问题,也是提高这类油藏采收率的关键。文章在国内外气顶油藏开发经验的基础上,探讨了气顶油藏的开发特点和开采方式,分析了各种开采方式在开发过程中的差异,为同类油气藏的合理开发提供经验和借鉴。
For gas cap reservoirs,the oil/gas/water distribution is crisscross,the drive types are so many and the oil/gas/water movement is very complicated.The core of development control and adjustment and the key of EOR are to push evenly both oil/gas and oil/water interface by means of gas cap and edge water in order not to generate both water and gas channeling so early at interlayer and plane.According to some experiences on gas-cap reservoir development at home and abroad,this papers discusses the development characteristics and patterns,analyzes the differences among various patterns and provides the guidance for the reasonable development of similar oil and gas reservoirs.
