Comparison of Nitrogen Gas and Thermal-Insulation Liquid to Control the Temperature–Pressure Effect in Deep Gas Well

Thermal-insulated liquid and nitrogen gas are two common methods to control the trapped annular pressure caused by the temperature–pressure effect, but few researches analyzed the control performance of these two measures applied in the deep gas well. Therefore, this paper builds a model to compare...
