摘　　要：深水深层超高温井测试存在井下封隔器易失封、工具易失效、井筒结水合物等难题,相比常规深水测试面对的挑战难度更大。以南海东部首次深水深层超高温X井测试实践为例,结合井况和储层特征,进行测试工具优选和测试管柱优化,开展测试液选型和射孔器材选配,优化井筒清洁、水合物防治和环空压力管理方案,通过现场应用,测试工艺成功,并大幅缩短了作业周期。该技术为类似油气井测试方案制定和安全高效施工提供了借鉴。Well testing for deep-water and deep reservoir well with ultra-high temperature has many problems, such as packer loss, tool failure and wellbore hydrate formation, which is more difficult than conventional deep-water testing. Taking the first testing for deep-water deep reservoir with ultra-high temperature of well X in the east of South China Sea as an example, combined with well conditions and reservoir characteristics, the paper optimized the testing tools and string, carried out the selection of testing fluid and perforating equipment, optimized the scheme of wellbore cleaning, hydrate prevention and control as well as annulus pressure management. Through field application, the testing technology was successful, and the operation cycle was greatly shortened. This technology provides a reference for similar oil and gas well testing scheme formulation and safe and efficient construction.
