Relativity analysis of regional soil property is useful for the soil corrosion estimation on the basis of certain appropriate indicators. This is significantly important for the corrosion control of oil & gas pipeline engineering. However, as we all know, soil properties is extremely complicated in natural environment. Large data dispersion error of the in-situ soil property measurement has been found out. Obviously, routine data statistical methods can not be used in such situation. The Kriging method of spatial data analysis has been applied on the project of typical soil property data according to the field measurement. At the same time, the data analysis software has been developed to deal with the soil characters specified. 300 on-site data have been processed，and the corrosion classification map has been founded based on the evaluation indicators of soil resistivity. This paper described the principle and basic procedures of Kriging method used in soil corrosion assessment, as well as relevant software development and its application.
