Abstract

This study investigates the heat dissipation mechanism of the insulation layer and other plane insulation layers in the polar drilling rig system. Combining the basic theory of heat transfer with the environmental requirements of polar drilling operations and the characteristics of polar drilling processes, we analyze the factors that affect the insulation effect of the drilling rig system. These factors include the thermal conductivity of the insulation material, the thickness of the insulation layer, ambient temperature, and wind speed. We optimize the thermal insulation material of the polar drilling rig system using a steady-state method to measure solid thermal conductivity. By analyzing the distribution of temperature in space after heating, we optimize the distribution and air outlet angle of the heater using Fluent hydrodynamics software. The results demonstrate that under polar conditions, polyisocyanurate with stable thermodynamic properties is selected as the thermal insulation material. The selection of thermal insulation material and thickness significantly affects the thermal insulation effect of the system but has little effect on its heating effect. Moreover, when the air outlet angle of the heater is set to 32.5°, the heating efficiency of the system can be effectively improved. According to heat transfer equations and heat balance theory, we determine that the heating power required for the system to reach 5°C is close to numerical simulation.
