Investigation and analysis of the dynamic anomaly of deepwater temperature in Yong’an well

Based on the analysis of the dynamic background characteristics of Yong’an water temperature, the cause of the large fluctuation has been investigated and verified. Through comparative analysis of observed data, downhole TV detection and investigation of the borehole environment, it is found that the factors affecting the water temperature dynamics are due to the limitation of the well conditions and the site environment. It is suggested to carry out the transformation of the well.
