英文摘要The processing of semi-airborne electromagnetic data (SAEM) mainly adopts1D or quasi-2D inversion, which is not conducive to fine detection. By targeting 2.5D inversion problem of SOTEM, a hybrid algorithm based on particle swarm optimization (PSO) and lateral constraint inversion (LCI) is optimized. PSO can remove dependency on the starting model and improve the accuracy of interpretation. LCI may overcome the disadvantages of PSO, such as low convergence rate and over-stochastic problem. The cosine probability function varying with the number of iterations is used to merge the two algorithms to arrive at a compromise between precision and speed. Compared with the particle swarm optimization algorithm, the convergence speed of the hybrid algorithm is significantly accelerated in the late stage and successfully suppresses the over-stochastic problem. Lastly, the new algorithm is applied to the inversion of the data measured by the coal mine target.
