In this paper, the authors establish a rational porosity interpretation model. The method of porosity logging interpretation is a commonly used way for porosityinterpretation. Use unary line regression and binary line regression method to build porosity model. After comparison and validation, it indicates that for sandstone reservoirs in Zichang area, the porosity interpretation model established by unary line regression method, the correlation is low, the binary line regression method is better.
