Rock resistivity parameters are important data for reservoir oil saturation evaluation and reserve calculation by logging data. Laboratory core testing is the only way to obtain rock resistivity parameters. Influencing factors on the test results of rock resistivity parameters for the low permeability sandstone reservoir in Shengli Oilfield were analyzed from two aspects of experimental methods and experimental conditions. By means of factor comparison experiment，the influence of displacement method，displacing fluid，temperature，confining pressure and brine salinity on cementation exponent m，saturation exponent n and lithology factor a and b was discussed. The research results show that quasi-static displacement process of semipermeable plate method is similar to the oil accumulation of the oil reservoir whatever the displacement media is. The rock resistivity parameters is not sensitive to the experiment temperature，but is influenced by confining pressure and formation water salinity greatly. At last，technique of laboratory measurement of rock resistivity parameters for the low permeability sandstone reservoir was determined. Experimental water was prepared using the formation water with the same salinity，the semipermeable plate method was applied for water drive by gas or by oil，effective overburden pressure was simulated on the condition of indoor temperature，and the rock resistivity parameters of the low permeability sandstone reservoir were tested.
