The Study of Daqing Oilfield Class II Reservoirs Pore Throat Ratio Using Conventional Pressure Mercury Method

Abstract:

Through the Conventional pressure mercury experiment, the pore structure characteristics of the Class II reservoirs were studied in Daqing, and the conventional mercury penetration experiment date of 26 natural cores of Class II reservoirs were obtained, the pore volume, permeability contribution and pseudo pore-throat ratio distribution of different pore radius interval in Class II reservoirs were analyzed, the distribution characteristic of pore radius, throat radius and pore-throat ratio of Class II reservoirs were researched. The results showed that more than 60% of the Class II reservoirs pore volume distributed in the pore radius interval from 0.1μm to 5μm, the range of pore-throat ratio was 1.5~89.5. Therefore the reservoir space range of Class II reservoirs was from 0.1μm to 5μm.
