南海东部不同类型油藏流场重构技术研究

Study on flow field reconstruction technology of different types of reservoirs in the eastern South China Sea

流场重构是实现剩余油有效挖潜的重要技术措施,南海东部各油藏开发方式、油藏类型、驱动类型各异,需针对不同类型油藏制定相适应的流场重构模式。针对边底水天然能量开发油藏中主控因素井间干扰、隔夹层、井网井距和注水开发稠油油藏中主控因素地层压力、生产压差、井网井距,形成靶区油藏2类6种流场调整模式。

Flow field reconstruction is an effective method to enhance the development of the remaining oil.However,it should be developed base on reservoir type.In South China Sea,for natural energy driven edge water reservoirs,most influential factors including inter-well interference,interlayer,well pattern and spacing are considered.For waterflooding developed heavy oil reservoirs,reservoir pressure,production differential pressure,well pattern and spacing are considered.Two types and six kinds of flow field reconstruction modes are developed.
