To provide a technology for estimating a geological distribution.
A geological estimation system includes: resistance acquisition means for acquiring resistance when placing a long burial object to be buried underground to the ground; conversion means for converting the resistance acquired in the resistance acquisition means to penetration force in a cone penetration test; bed distribution generation means for processing the penetration force converted in the conversion means and generating the bed distribution of an area where the burial object is buried; and output means for outputting the bed distribution generated in the bed distribution generation means. The conversion means includes: distal end resistance force calculation means for processing the resistance acquired in the resistance acquisition means and calculating distal end resistance force acting on the distal end part of the burial object in a placing direction; peripheral surface friction resistance force calculation means for processing the resistance acquired in the resistance acquisition means and calculating peripheral surface friction resistance force acting on the peripheral surface of the burial object; and penetration force calculation means for processing the distal end resistance force and the peripheral surface friction resistance force and calculating the penetration force of the burial object when placing the burial object.
