海油陆采平台护底方案优化研究——以胜利油田垦东12区块3号平台为例

Study on the Optimal Plan for Protection of Onshore-platform Under-pan for Offshore Oil Recovery——An Example of the No.3 Platform in KendongNo.12 Area of Shengli Oil Field

胜利油田垦东12区块3号海油陆采平台位于进海路端头,防护非常重要。通过建立潮流数学模型及理论计算确定护底宽度,进而对护底结构进行了优化研究。经过经济技术对比,优选出砼联锁块软体排+局部抛石结构为3号平台的护底结构方案,该方案具有现场施工效率高,后期维护工作量少的优点。

The No. 3 onshore-platform is located at the end of Jinhai Road in Kendong No. 12 Area of Shengli oil field. It is very important to protect the platform. A mathmetical model for tide is established to calculate and determine the platform under-pan width, and to oplimize the under-pan structure. Based on the detailed comparison in economics and technology, an optimal plan is suggested for the under-pan structure of the No. 3 platform, which made of machine-made cloth and adhesive-bonded cloth weighted with concrete block rows, and partly with dropped rocks. This plan can be effieently implemented in the field engineering, with its advantages for less amount of work in the later maintainance.
