Abstract
In the long-distance pipeline of product oil, gasoline and diesel oil are transported in batches. Due to the large difference of physical properties between the two kinds of oil products, there will be oil mixing at each interface. Because the index parameters of mixed oil do not meet the sales standard, it is necessary to track the interface accurately, so as to provide necessary reference for cutting mixed oil. The topography of southwest mountainous area is characterized by continuous large drop and U-shape, which brings difficulties to batch tracking of product oil pipeline. The previous method is not suitable for this type of pipeline. Therefore, it is necessary to re study the batch tracking method of this type of product pipeline, and use vs2019 to write batch tracking software for continuous large drop and U-shaped product pipeline based on this method. The batch tracking error of the software for this type of pipeline is within the acceptable range, which can provide more accurate reference for the operation control personnel

The previous method is not suitable for this type of pipeline, so it is necessary to re study the batch tracking method of this type of product pipeline, and write batch tracking software for continuous large drop and U-shaped product pipeline based on this method
When two kinds of oil products alternate in the pipeline, the amount of mixed oil varies greatly under different flow regimes, because the mixing mechanism is different under different flow regimes
Summary
The construction, development and rise of domestic product oil pipeline are relatively late, and the research on batch tracking of product oil pipeline is relatively late. Until 2005, domestic scholars began to pay attention to the tracking of batch interface of crude oil and product oil pipelines [1,2,3], and some scholars used Excel software to track the batch operation position of Sinopec South China pipeline network [4], and some scholars applied online batch interface calculation software to PetroChina Western product oil pipeline and Lanzhou Chengdu Chongqing product oil pipeline [5,6]. There are Hengduan Mountains in Southwest China, which are characterized by continuous large drop and U-shape, which brings difficulties to batch tracking of product oil pipelines. The previous method is not suitable for this type of pipeline, so it is necessary to re study the batch tracking method of this type of product pipeline, and write batch tracking software for continuous large drop and U-shaped product pipeline based on this method
