渤中34-1N钻井帽在锦州9-3油田井口平台上的应用

摘要

The drilling cap of BZ34-1N was founded in 2009 for the drilling and completion operation in BZ34-1N oilfield along with a non-cantilevered drilling ship (Bohai 5) over the platform jacket. However, the drilling cap, upon its completion, has been placed in the construction site for 4 years on the account of the cantilevered drilling ship. Given the comprehensive adjustment of JZ9-3 oilfield project, a four leg wellhead platform is to be built. It is thus considered to use the drilling cap over the JZ9-3 oilfield jacket to complete the relevant work. Hence, the drilling cap needs further transformation for its adaptability.%渤中34-1N钻井帽始建于2009年，计划在渤中34-1N油田利用其与非悬臂式钻井船(渤海5号)在导管架上方进行钻完井作业。但在钻井帽建造后期，悬臂式钻井船的紧张局面得到缓解，钻井帽被放置于建造场地4年。鉴于锦州9-3油田综合调整项目新建1座四腿井口平台，初步考虑利用钻井帽在锦州9-3油田井口平台的导管架上进行钻完井作业。因此，需要对钻井帽进行适应性改造。
