Safety management of high-pressure gas wells is a prerequisite for ensuring the safe production of high-pressure gas wells. In recent years, with the continuous production of high-pressure gas wells in front of Kuqa Mountain, some gas wells have experienced abnormal annular pressure, which has increased the risk of gas well management. The key points of high-pressure gas well production management are to determine the range of annular pressure control, determine the safety status of abnormal pressure wells, and ensure long-term safety production of high-pressure gas wells. Due to insufficient understanding of these risks in the early stage, effective measures were not taken during the oil testing design and construction process, resulting in multiple high-pressure gas wells experiencing incidents such as tubing string failure and casing deformation during the oil testing process, resulting in operation failure or even scrapping. This article evaluates the annular pressure and control mechanism of high-pressure gas wells based on the current concept of integrity, which cannot meet the complex factors of high-pressure gas wells, and combined with the characteristics of high-pressure gas reservoirs in front of Kuqa Mountain;
