【摘要】 针对基岩、裂缝、溶洞三重介质油藏,在考虑裂缝和溶洞均与井筒连通的情况下,进行三重介质物理模型描述,提出双渗三重介质概念,建立双渗三重介质油藏数学模型,并通过拉普拉斯变换和数值反演法对数学模型进行求解。提出的三重介质缝洞型油藏数学模型,为更好地应用现有的数值模拟软件模拟缝洞型油藏提供了依据。更多还原

【Abstract】 A physical model of triple medium is described by considering that both fracture and cavity are connected to well bore in reservoirs with triple medium of matrix, fracture and cavity. A concept of dual-permeability triple medium is proposed and a mathematical model is built. This mathematical model is solved by using the Laplace transform and numerical inversion methods. This model for triple medium fracture-cavity reservoir is helpful to reservoir modeling with existing simulators.更多还原
