Zusammenfassung:	A method for predicting the corrosion rate of a pipeline in a complex oil and gas environment relates to the field of corrosion rate prediction, and comprises the following steps: S1, constructing a corrosion rate base table according to corrosion rate data under various environmental parameters; s2, determining the independence among various environmental parameters through the correlation coefficient matrix, keeping the consistency of other parameters, analyzing the influence degree and rule of a single environmental parameter variable on the corrosion rate of the pipeline, and establishing a linear interpolation calculation program; and S3, inputting the environmental parameters of the actual working condition into an interpolation calculation program, and obtaining a predicted corrosion rate according to the corrosion rate base table data. According to the method, the influence of each influence factor on the corrosion rate can be analyzed and determined based on the corrosion mechanism in a complex oil a
