In order to study the difference of pore structure characteristics between the second oil reservoir and the main oil reservoir in Daqing oilfield, the pore structure characteristic parameters of core were characterized by routine mercury injection experiment. The results show that the average pore radius of the main reservoir ranges from 5.24μm to 12.50μm, the sorting coefficient ranges from 1.14 to 3.08, the median saturation pressure ranges from 0.04MPa to 0.27MPa, and the maximum median radius can reach 15μm. The permeability is high and the displacement pressure is low. The average pore radius of the second type reservoir is in 2.21μm~9.03μm, the sorting coefficient is 2.70~4.77, the median saturation pressure is 0.076MPa~5.148MPa, the maximum radius is only 5μm, and the permeability is low and the displacement pressure is high. It is important to clarify the difference of reservoir pore structure characteristics for efficient reservoir development.
