摘要
气顶油田油、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,在层间和平面不过早发生水窜和气窜是开发控制和调整的核心问题,也是提高这类油田采收率的关键。本文在国内外气顶油田开发经验的基础上,探讨了气顶油田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,为同类油气田的合理开发提供经验和借鉴。
Gas cap oilfield is characterized by interlaced oil - gas - water distribution, various drive types and com- plicated oil -gas -water movement. Using gas -cap and edge water energy to advance oil -water interface and oil -gas interface evenly, avoiding water channeling and gas channeling early appearing in interlayer and plane are the central problems for development controlling and adjustment, and also the key to increase oil recovery. Based on the experience of gas cap oilfield development at home and abroad, development characteristic and recovery method are discussed, and the differences of a variety of methods during the development are analyzed, which pro- vided experience and reference for reasonable development of the similar oilfield.
