摘要
Based on the dual water saturation model, in this paper, the authors select the typical rock samples of Fuyang reservoir to test, for establishing the relationship between formation factor F with porosity, permeability, clay and calcium content, at the same time, according to the experiment to set up the relationship between saturation exponent n with porosity and permeability. So it made the formation factor F and saturation exponent n more suitable for low permeability and porosity reservoirs of study area. Verified by coring well, the relative error of the calculation of saturation is 7.6%, meeting the requirements of actual production.
