Using a large amount of data calculated by the author in the three-dimensional numerical model of well flow and heat transfer in the well, the article systematically analyzes the sensitivity of many factors that affect well temperature. The results show that the thermophysical parameters such as drilling fluid and formation, Drilling fluid inlet temperature, circulating displacement and other temperature have a greater impact on the temperature, therefore, accurate understanding of the drilled area of the formation and drilling fluid thermal physical parameter values, taking into account the temperature and pressure on the thermal physical parameters, accurate measurement of drilling fluid Parameters such as inlet temperature, displacement and so on are of crucial importance for accurate simulation of well temperature.
