This invention relates to the field of pipeline corrosion prevention technology, specifically a method for obtaining the drying time of the water film on the inner wall of a pipeline during a CO2 gas-water alternating process. The method involves obtaining the saturated water content of a single-stage plug and the water content of the water film on the inner wall of the pipeline, assuming the CO2 flow state within the pipeline is supercritical and highly turbulent. Then, it determines the effective number of drying plugs required to completely dry the water film on the inner wall. Based on the effective number of drying plugs and the single-stage plug passage time, the drying time of the water film on the inner wall is obtained. This invention, by accurately calculating the drying time of the water film on the inner wall of the pipeline, can optimize the set duration of the CO2 gas-water alternating injection, avoiding cost waste or corrosion risks caused by over-injection or under-injection. It achieves efficient corrosion prevention of pipelines with CO2 gas-water alternating injection at low cost. Simultaneously, it can output multi-dimensional data such as drying time, CO2 consumption, and the distribution of parameters along the pipeline, providing a scientific basis for pipeline corrosion risk assessment and drying process optimization.
