| 摘 要： | 针对微裂缝低渗透砂岩油藏普遍存在的测井渗透率与油田开发实际渗透率差异较大的矛盾,提出以油田实际生产目的层段为单位,应用平面径向流产能公式,结合油田初产资料求取动态渗透率,引入校正系数,将测井渗透率校正到油田开发动态渗透率的方法.应用该方法对靖安油田白于山区微裂缝低渗透砂岩油藏进行测井渗透率校正,建立油藏数值模拟的渗透率模型.结果表明:应用该方法校正的测井渗透率所建立的渗透率模型拟合效果更加符合油田开发实际状况.

| Abstract: | For micro-fractured low permeability sandstone reservoirs,logging permeability usually differs a lot with actual permeability in oilfield development; therefore it is proposed to apply productivity formula of radial fluid flow to derive dynamic permeability based on target reservoir interval and preliminary production data,and to introduce a correction coefficient to revise logging permeability to oilfield dynamic permeability. This method has been successfully applied to logging permeability correction and... |
