The invention discloses a resource exploitation method and device based on shale reservoir relative permeability, and belongs to the technical field of oil-gas field development. According to the method, the flow models of the liquid-phase fluid and the gas-phase fluid in the single nanopore are established respectively, and the slip length and the effective viscosity of the fluid related to the flow models are corrected based on the actual flowing condition of the multi-phase fluid in the nanopore, so that accurate fluid flow and flowing state characteristics are obtained; according to the method, the relative permeability of the shale reservoir is obtained, and the accurate relative permeability is obtained in combination with the actual nano-pore structure, so that corresponding working parameters are determined according to different relative permeability during resource exploitation, and the exploitation efficiency and yield of shale reservoir resource exploitation are improved. 本申请公开了一种基于页岩储层相对渗透率的资源开采方
