| 摘 要： | 运用混合法的对偶形式给出了纵向成层、径向不均匀的轴对称介质中位场格林函数的数值解,并将其应用于普通电阻率测井响应的数值分析。由于该算法对问题进行了降维处理,和有限元法相比,具有明显的速度优势。

| Abstract: | The numerical solution of Green's function for potential in axisymmetrically stratified media with axial inhomogenity is given using the duality of the hybrid method,which is then applied to the computation of response of the fundamental resistivity tool.Compared with the 2D finite element method,this algorithm is of higher efficiency because of the reduction of the problem dimension. |
