摘要
目前确定初始含油饱和度场的方法主要有单相渗曲线法、井间插值法和J函数法,本文在简要介绍这三种方法的基础上,通过实例应用对比表明,J函数法建立的初始含油饱和度场更能体现出油藏高度的变化,更符合非均质油藏实际特征,为进一步准确描述剩余油潜力提供了坚实的基础。
At present, the methods to determine the initial oil saturation field mainly include single-phase permeability curve method, interwell interpolation method and J function method.In this paper,on the basis of the brief introduction of these three methods, the comparison of examples shows that the initial oil saturation field established by the J function method can better reflect the change of reservoir height and is more consistent with the actual characteristics of heterogeneous reservoirs, which provides a solid foundation for further accurate description of remaining oil potential.
