一种水驱油藏开发后期的剩余油预测方法

Remaining oil description method at late oil development stage of water drive oil deposit

根据油田开发过程中剩余油饱和度变化规律,结合相关地层参数适宜性评价和两相流体渗流机理理论,建立了兼顾油水两相平衡剩余油动态预测模型;并应用不同开发阶段测井信息,提出一种水淹层测井评价与数值模拟方法相结合的剩余油预测方法,并根据此方法编制了剩余油描述软件,在大庆杏南开发区应用,效果较好.

According to the changing rules of remaining oil saturation during the oil field development, the remaining oil performance forecast model of oil-water phase equilibrium was established through the combination of the related formation parameter evaluation and the seeping mechanism of two phase fluid. Using the logging information at different development stages, a method combining water flooded zone logging evaluation was developed to evaluate and predict remaining oil. The remaining oil description software was programmed and applied in Daqing Xing-nan developing zone.
