A New Method of Determining the Lower Limit of Pore in Saturated Kerosene

To determine the lower limit of pore size saturated kerosene indirectly for testing porosity, combined total porosity was first calculated using carbon dioxide adsorption, nitrogen and mercury intrusion tests. Then is gradually accumulated from large pores to tiny pores. When accumulation equal corresponding diameter a minor measured by porosity. A 5 samples were collected this time. The determined as 3.1nm, which shows that saturation method can describe most shale's mesopores macropores. This also be extended method, such helium.
