【摘要】 针对裂缝油藏特点,以Fraca裂缝建模软件为平台,以Gocad基质属性建模成果为基础,分析各种不同的地震属性对储层及裂缝的响应特征,计算不同的变差函数,建立杨家坝油田的裂缝模型,并将裂缝的几何模型转化成裂缝渗流模型。结合储层基质属性模型,建立双重介质孔渗属性模型,为数值模拟提供地质参数,为油田调整挖潜提供依据。更多还原

【Abstract】 According to the characteristic of fractured reservoir,based on the fracture modeling software of Fraca and modeling results of matrix attributes,analyzing all sorts of response characteristics of seismic attributes corresponding to the fractured reservoirs,calculating variogram,fracture model of Yangjiaba Oilfield is set up.The geometry model is transformed into fracture seepage model.Combining with matrix attribute model,dual porosity-permeability attributes model is founded to provide geological parameters for numerical modeling and adjusting production.更多还原
