摘　　要：高温高压气井通常存在多种风险影响气井完整性,需要应用集成新技术解决各类潜在风险。针对塔里木油田库车山前高温高压气井新技术应用面临的各项挑战,综合技术评估、风险评估和性能评估方法,建立了一套适合于高温高压气井的新技术评估方法。通过应用高温高压气井新技术评估方法开展新技术的潜在风险、失效模式、技术缺陷、适用条件等评估,可确定新技术的应用范围、应用要求及改进方案。封隔器应用案例分析表明,考虑现有技术控制措施对风险降低的影响后,能快速得到部件的风险及风险零件占比,方便后续针对性进行验证测试,提高封隔器使用的可靠性和环境适应性。该新技术评估方法能够有效促进高温高压气井新技术的推广应用和持续改进。The integrity of high-temperature and high-pressure(HTHP)gas well is usually vulnerable to multiple risks.It is necessary to integrate new technologies to address the potential risks.In the Kuqa piedmont of the Tarim Oilfield,where the application of new technologies to HTHP gas wells is very challenging,a new technology assessment method for HTHP gas wells was established by integrating technology assessment method,risk assessment method,and performance assessment method.The new technology assessment method can be used to evaluate the potential risks,failure modes,technical defects,and applicable conditions for a new technology,so as to determine the application scope,application requirements,and aspects to be improved.The analysis on packer application shows that after considering the impact of existing technical control measures on risk reduction,the proportions of risky components and risky parts can be quickly obtained for subsequent targeted verification testing and improving the reliability and environment adaptability of the packers.The new technology assessment method can effectively promote the popularization,application,and continuous improvement of new technologies for HTHP gas wells.
