摘要
The study of efficient inversion method was carried out for continuous formation, targeting at improving the inversion precision and efficiency of 3-dimensional (3D) induced polarization (IP) data with waved geometry. Blocky continuously varied parameterization based on tetrahedral element was developed for the continuous changed resistivity model with fluctuated geometry. Finally, the effectiveness of the inversion method was tested by two examples. The numerical results show that the inversion converges within 6 iterations and takes very little computational time. The inversion software developed can be used to interpret the real data.
