渤海油田可移动井口平台总体方案

摘要

Aimed at the present situation of offshore marginal oil field in China,and combined with the offshore marginal oil field development model,a type of removable wellhead platform suitable for the range of 40 meter water depth is developed,which can be used to replace the conventional fixed unmanned wellhead platform.The platform adopts the jack-up structure and stern wellhead support structure,and has advantages of a short construction period on land,short offshore installation time,low disposal cost etc.It's of great significance to the development of marginal oilfield in the future.%针对我国海上边际油田现状进行阐述,并结合海上边际油田开发模式,研究出一种适合于我国40 m水深范围内的可移动井口平台,用以替代常规固定式无人井口平台.该平台采用自升式结构型式,艉部设有井口支持结构,具有陆地建造周期短、海上安装时间短、弃置费用低等优点.该研究对边际油田开发具有重要的意义.
