Calculation of Soil Natural Temperature Field in Cold Region and Analysis of Influencing Factors
Soil properties directly affect the temperature change of crude oil in buried pipelines in cold regions, and clarifying soil temperature field and its influencing factors is the key to production management in gathering and transportation field. In this paper, a mathematical model for calculating soil natural temperature field was established to analyze the influence of frozen and unfrozen soil physical properties on soil natural temperature field, and to clarify the influence of soil physical properties parameters on soil temperature, delay time, freezing time and starting time of freezing, so as to provide theoretical support for thermal calculation of buried pipelines.
