Abstract

The invention provides a stratum capture cross section curve processing method and device, equipment and medium. The method comprises the steps: resampling an actual measurement capture cross section curve in collected logging data, carrying out parameter calculation by employing a pre-trained linear model according to the sample data obtained through the resampling, obtaining an inversion parameter, substituting the inversion parameters into a volume model for calculating the capture cross section curve, obtaining a final inversion curve, namely, the original capture cross section curve of the stratum can be obtained, so that a water flooded layer of the stratum can be evaluated subsequently, the stratum is evaluated on the basis of the inversion curve, the influence of a skeleton and argillaceous substances on the capture cross section can be eliminated, and the evaluation precision is improved.
