Abstract:
At present, most of the existing data processing software for TEM only aim at the loop source devices, and can not deal with the data of the electric source devices. With the wide application of SOTEM, it is urgent to develop a set of data processing software suitable for SOTEM. By solving the key techniques of one-dimensional forward modelling for arbitrarily transmitters-receivers, joint inversion of multi-component and multi-source data, inversion of data with induced polarization effect, quasi-2D lateral constrained inversion, etc., SOTEMsoft, a special software system for SOTEM data processing was developed. The system has the functions of data arrangement, image display, data pre-processing, model building, forward modelling, data inverse, drawing input and so on. The results of numerical simulation and field data processing show that SOTEMsoft has perfect function, high precision and efficiency of data processing, and can meet the actual production requirements in field.
