  Rock electrical data plays an important role in the logging interpretation for reservoir evaluation and reserves prediction.While based on the digital core,rock electrical numerical simulation technology can make up for the deficiencies of traditional rock physics experiment,such as long experimental period,high cost and the difficulty of core displacement.Determining the fluid distribution in the pore accurately is the basis of the numerical simulation of the electrical,most of scholars at home and abroad by using the pore network model with finite element method to carry out the digital core electrical numerical simulation research,but the research of combining mathematical morphology method with other simulation methods,such as lattice boltzmann method,kirchhoffs circuit node method,the random walk method was still in its infancy.After carry out a wide range of literature research for the various methods above,in this paper,the advantages and disadvantages of combining the pore network model or mathematical morphology with other simulation methods to do the electrical numerical simulation research are analyzed.So we put forward a new method that combined mathematical morphology with random walk,and on the basis of predecessors research we considered the connectivity of digital core,anisotropy,water film and other factors,then the simulation results match well with the experiment,which confirmed the feasibility of new method,laid a solid foundation for the electrical digital simulation study.
