The signal processing of induction logging is thoroughly studied, and the research results in recent ten years in the theories in signal processing of induction logging, the optimization design of filter, and the implementation of the processing of non-linear measurement are comprehensively stated. The limitation of the common geometrical factors is summarized; the idea of solving the problems in the optimization design of filter by related techniques and soft constrain methods is proposed; combining true resolution focusing with resolution matching greatly reduces the effects of borehole; adaptive non-linear processing of measurement is implemented. The results of this paper are applied to dual induction logging, high resolution induction logging, array induction image logging(AIT) and high resolution array induction log(HDIL).
