Using NMR T2 spectrum distribution to study fractal nature of pore structure
Online published: 2008-03-15
It is a newmethod to analyze the fractal nature of pore structure and petrophysical property by using NMR T2 spectrum distribution. Based on the former study, the fractal nature of the medium-high porosity and permeability reservoir is analyzed, and then the applicability and reliability of this method are discussed in low porosity and low permeability reservoir, finally, the application effect of this method in medium-high porosity and permeability reservoir is compared with the effect in lowporosity and lowpermeability reservoir. The result shows that it could determine the fractal nature of pore structure exactly and calculate the fractal dimension by using NMR T2 spectrumdistribution. The fractal dimension calculated by this method could characterize the petrophysical property closely and provide reference for reservoir characteristics research and reservoir classification.
