Method and device for predicting fluid pressure coefficient of shale formation rich in organic matters

The invention discloses an organic-matter-rich mud shale formation fluid pressure coefficient prediction method and device, a storage medium and computer equipment, and the method comprises the steps: based on apatite fission track age and length distribution data, through fission track length simulation, determining the uplift time and the uplift denudation process, and according to ancient temperature scale Ro data, through ancient temperature scale inversion, calculating the fission track length distribution data; the method comprises the following steps: determining the uplift time, determining the denudation amount, on the basis of the uplift time, the denudation amount and denudation amount recovery, obtaining the maximum vertical effective pressure endured by the shale in the geological historical period through burial history recovery, and after the maximum vertical effective pressure and the current vertical effective pressure are determined, determining the OCR value of the shale.
