Method and device for determining irreducible water saturation parameters and computer equipment

The invention provides a method and device for determining irreducible water saturation parameters and computer equipment, and belongs to the technical field of oil field reservoir evaluation. The method comprises the following steps: determining a target reservoir to be researched and a target well section of a standard well; based on nuclear magnetic resonance logging data, first element capture logging data and first conventional logging data of the target well section at each sampling depth, determining a clay water volume coefficient of the target reservoir and a micropore bound water volume coefficient and clay content of the target reservoir at each sampling depth; and for each sampling depth of a non-standard well, determining bound water saturation parameters of the target reservoir at the sampling depth based on the second element capture logging data, the second conventional logging data, the clay water volume coefficient of the target reservoir and the micropore bound water volume coefficient and
