| 摘 要： | 针对电法测井中遇到的全非均匀的二维地层模型，将深浅侧向视电阻率曲线作为约束条件，提出了计算地层真电阻率及侵入半径的一种快速迭代反演方法。数值模拟和实际资料处理的结果表明，所有反演计算结果均与实测结果吻合，且地层电阻率的吻合程度最高，高分辨率三侧向资料的反演比普通三侧向资料更为精细。

| Abstract: | The radially and vertically inhomogeneous formation models are widely encountered in electrical well logs. Taking the deep and shallow apparent resistivity curves as constraint conditions,a rapid iterative inversion method is put forward for inversion of virgin resistivities and radius of invasion zone. The results of numerical simulation are in good agreement with those of field examples. |
