Abstract

The results of modelling non-isothermal oil movement in a section of the main oil pipeline are presented. It is emphasised that finding effective oil transportation methods through the pipeline system is a topical issue related to establishing rational pumping modes. The feasibility of using modern mathematical programming methods and application software is determined; however, the latter requires direct participation from programmer users with an understanding of the development area. To study the thermal and hydraulic characteristics of oil flow in an oil pipeline, it is necessary to consider many factors and select the correct determinants. The main stages of the modelling process are presented: construction of the oil pipeline geometry in the Fusion360 programme; compilation of a physical and chemical oil model in the PVTSim Nova programme; and modelling of heat transfer and hydrodynamics in the COMSOL Multiphysics programme. An example of the calculation of the transportation of heated viscous oil is given, in which the oil enters the main oil pipeline at a temperature of 50 °C. The pipeline is a shallow-laid underground pipeline at a depth of 0.9 m. The change in oil temperature along the cross-section and length of the channel was studied, taking into account losses to the environment. It has been proven that a decrease in soil temperature is accompanied by a decrease in oil temperature. This corresponds to the physical process of cooling a moving fluid in a pipeline. The temperature changes across the cross-section in accordance with physical laws, indicating the feasibility of using the selected program for thermal calculations. According to the modelling results, data on oil velocity and pressure changes along the length of the pipeline were obtained. The presented data on pressure changes takes into account costs along the length of the oil pipeline; however, it would also be possible to include the difference in geodetic heights and costs at local supports in the program.
