Abstract: Based on the experimental data of core properties and mercury curve,the pore structure study of glutenite reservoirs in Hailar oilfield has been carried out.The results indicate the glutenite reservoir properties vary greatly and the correlation between porosity and permeability is poor.The pore throat radius distribution is bimodal based;the permeability and average pore radius has a better power function.The logarithmic and sorting permeability logarithmic factor characteristic structural parameters are of good linear relationship,the displacement pressure and permeability has a double logarithmic linear relationship,a linear relationship with the sorting coefficient.The retreat mercury efficiency and permeability has power function,and a linear relationship with the sorting coefficients.
