Abstract: The quantitative evaluation and productivity prediction of heterogeneous carbonate reservoir is keeping a hard-solved problem in well logging analysis,the characteristic of heterogeneous reservoir is analyzed by using such data as imaging logging,NMR logging and dipole sonic logging,the pore size and the relation between the size and permeability are also analyzed with NMR logging,the application of POROSPECT calculation result in describing primary and secondary porosity is introduced,the approach quantitatively describing heterogeneous reservoir with imaging logging and NMR logging is studied,the development degree of pore,vug and fracture,the total porosity,secondary porosity,permeability,the relation of pore size and productivity,as well as the suitability of evaluating productivity with NMR logging and imaging logging are all studied.

Key words: heterogeneity, carbonate rock, reservoir, pore and vug, fracture, productivity
