Study of the dynamics of changes in the thermal conductivity coefficient of organic deposits

ABSTRACT Ensuring flow in an oil field is one of the most costly problems in oil production and transportation. The fight against the formation of paraffin deposits consists both in the application of methods for the prevention and removal of deposits, and in the modeling of this process. An important parameter for the application of some technologies for preventing the formation of deposits and modeling the temperature regime of the pipeline is the coefficient of thermal conductivity of these deposits. The paper presents a study of the influence of the thermal conductivity of organic deposits on the rate of their formation, measured for 5 hours at the Cold Rod installation. According to the research results, it was found that over time, the thermal conductivity of organic deposits increases, while the rate of deposit formation decreases significantly. This process is explained by an increase in temperature on the surface of deposits due to their compaction and displacement from the volume of the liquid phase. The results obtained are extremely important in modeling the process of deposit formation and modeling a number of technologies to combat them.
