摘要
三维感应测井能同时获得储层垂直、水平电阻率,可直接计算垂直与水平方向电阻率各向异性系数,该系数在储层流体识别方面的研究较少。进行物理模型、岩心实验数据分析,总结出岩样垂直电阻率与水平电阻率各向异性和岩性、流体的关系;分析典型流体的三维感应测井电阻率响应特征,总结出利用三维感应电阻率各向异性系数识别储层流体性质的方法。通过在12口井57个砂泥岩类储层段的现场应用,利用三维感应电阻率各向异性流体识别方法得到的解释结论与试油结论的符合率达91.2%。该方法在现场实践中取得了良好效果,为三维感应测井资料解释应用提供了一种新思路。
The vertical and horizontal resistivity can be obtained by three-dimensional(3D)induction logging,and the vertical-horizontal anisotropy coefficient of reservoir resistivity can be calculated directly.There are few researches on this coefficient in reservoir fluid identification.The relationship between the vertical-horizontal resistivity anisotropy and the lithology/fluid is summarized from the physical modelings and core experiments.By analyzing 3D induced resistivity anisotropy response characteristics of typical fluid types,the method of characterizing reservoir fluid based on resistivity anisotropy is concluded.The 3D induced resistivity anisotropic fluid characterization method is verified in 57 sandstone layers of 12 wells,with a matching rate of 91.2%.This method is achieved good results in field practice and provides a new idea for the interpretation and application of 3D induction logging data.
