流花11-1油田水下跨接管拆除技术要点分析

摘要

介绍流花11-1油田水下设施的跨接管接头的改造与利用工程。拆除流花11-1的旧跨接管，为流花4-1新建油田的水下生产系统所利用。分析改造施工中的各种创新技术，供类似的改造工程项目参考。%The transformation and utilization project of the subsea jumper in Liuhua 11-1 oil field was introduced .Two old subsea jumpers in Liuhua 11-1 were removed and reused in the new-built underwater production system of Liuhua 4-1 oil field. Some innovative technologies in the transformation project were analyzed , which can be referenced for utilizing and reusing of the old subsea facility in future .
