摘　　要：随着南海东部海上油气资源勘探开发需求的日益增长,大位移井数量呈逐年递增趋势。结合流花油田高水垂比大位移井井筒清洁难题、复杂地层井下高风险、尾管下入难度大等问题,开展关键技术研究和工程实践,形成了水下井口重建、浅层中&短曲率半径造斜、长稳斜延伸段井筒清洁、全掏空旋转下尾管等一套高水垂比大位移井提效集成技术,为后续海洋石油大位移井作业积累经验。With the increasing demand for exploration and development of oil and gas resources in the eastern South China Sea,the number of offshore large displacement wells is increasing year by year.This article combines key technology research and engineering practice with the difficulty of cleaning the wellbore of high water to vertical ratio and large displacement wells,the high risk of complex formations underground,and the difficulty of tail pipe insertion.It has formed the following key technologies:underwater wellhead reconstruction,shallow medium to short curvature radius deviation building,long stable inclination extension section wellbore cleaning A set of integrated technology for improving the efficiency of high water to vertical ratio and large displacement wells,such as a fully emptied rotating tail pipe,provides experience and ideas for subsequent offshore oil large displacement well operations.
