【摘要】 沉积相约束下的储层建模方法比较普遍,本文提出了岩石类型控制下的建模方法。采用Winland R35方法划分油藏岩石类型,建立不同岩石类型下孔隙度和渗透率关系模型;获得各口井岩石类型后,通过序贯指示模拟预测井间岩石类型,继而建立三维岩石类型模型;最后基于地震波阻抗属性约束孔隙度,建立孔隙度模型,再利用不同岩石类型下已建立的孔隙度和渗透率关系确定渗透率,建立渗透率模型。更多还原

【Abstract】 Carbonate reservoir modeling has been a research focus recently.This paper puts forward a 3D geological modeling method based on rock typing for carbonate reservoirs.we use Winland R35 method to identify the rock types of a carbonate reservoir.With the rock types of each well,3-D rock type model is built with sequential indicator simulation.The seismic acoustic impedance is used to constrain the porosity between wells,and the permeability is determined with the relationship between porosity and permeability for a specific rock type.3-D geological model is established with the constraint of rock types.更多还原
