Investigation and analysis of the dynamic anomaly of deepwater temperature in Yong’an well
-
摘要: 在分析永安井水温动态背景特征的基础上,对该井长期以来的大幅动态异常变化原因进行调查核实,利用观测数据对比分析、井下电视探测和井孔内外环境调查等方法,基本查明是由于井孔自身条件及场地环境所限,使得该井存在影响水温动态的因素,建议对该井进行井孔改造。Abstract: 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.
