A geological interpretation method for non-uniform survey

In recent years, time-domain electromagnetic method, as a rookie of electromagnetic method, is widely used in shallow surface physical survey. When the terrain is too steep, the survey points are distributed unevenly. This paper proposes a quasi-three-dimensional inversion method suitable for general conditions, which has universality. In addition, the current electrical survey and inversion methods have problems such as rough results and low accuracy. In order to obtain a better geological interpretation, this paper proposes a pseudo-three-dimensional inversion method suitable for non-uniform distribution. The simulation sets up a set of 3D models of underground isomers and background noise to simulate the actual environment. In geological interpretation, the outline of the model and the boundary of the strata are complete and smooth. The experimental results demonstrate the rationality and reliability of the method, and it is suitable for non-uniform field surveys.
