呼探1井属于高温高压超深井，针对试油过程中所面临复杂的地质条件、恶劣的井况条件、极端的工况条件等问题，开展了施工风险评估，结果显示，试油施工主要面临入井管柱埋卡风险、井筒安全风险和井控安全风险。通过优选光油管射孔测试一体化管柱进行施工，避免了入井管柱埋卡的风险；通过井筒安全校核、出砂预测和套压控制计算，设置套管最高限压，现场控制生产压差，消除了井筒安全风险；通过地面测试流程优化、实时跟踪分析、制定应急措施方法，有效控制了井控安全风险。呼探1井试油作业安全平稳运行，并试获高产工业油气流，日产气61×10⁴ m³、日产油106 m³，录取地层压力高达146.07 MPa。研究成果为高温高压超深井试油测试提供了技术借鉴。

Well Hutan 1 is an ultra-deep well with high pressure and high temperature. To address the challenges posed by complex geological conditions, adverse well conditions, and extreme operational conditions during the well testing process, a risk assessment of the construction was conducted. The well testing operation primarily faces three potential risks: pipe sticking in the well, well safety and well control risk. Innovative measures were taken to mitigate these risks. An integrated pipe string, optimized for perforation and testing, was used to avoid the risk of pipe sticking in the well. On the base of well safety check, sand production prediction and casing pressure control calculation, the maximum casing pressure limit was set, and the production pressure difference was controlled on-site, eliminating well safety risk. Through optimization of surface testing processes, real-time tracking and analysis as well 000 emergency measures, well control risk was effectively controlled. The safe and smooth well testing operation in Well Hutan gained a high-yield industrial flow of oil and gas, with daily gas production of 61×10 m and daily oil production of 106 m, the recorded reservoir pressure reached an impressive 146.07 MPa. The research results provide technical reference for oil testing in high-temperature, high-pressure and ultra-deep wells.
