冀东油田人工岛设计关键技术*

近年来冀东油田为满足滩海油藏勘探开发需要,成功建造了一系列海上人工岛.工程海域属粉砂质海岸,浅滩、深槽、沙脊交错分布,海域地形条件复杂.工程处于外海且无掩护,风浪流较大,冬季受冰冻影响且冰荷载大.滩海油藏勘探开发用人工岛,安全环保要求苛刻.这对人工岛的设计提出了较高的要求.对冀东油田人工岛设计关键技术进行总结分析,包括人工岛功能、选址、平面布置、建设标准、保滩护底措施、围堤结构、岛域吹填及地基处理、对外交通码头等人工岛设计所涉及的主要方面,可供同类工程参考.

Key technology for design of artificial gravel island in Jidong oilfield

In recent years, in order to meet the needs of sea beach reservoir explorations and developments, a series of artificial islands have been successfully constructed in Jidong oilfield. The project is characterized by silty sea-bed, shallows, deep grooves, sand ridges staggered distribution of the waters and complex terrain conditions. The project locates in the open sea and has no cover, larger storm flow and frozen affect in winter. The exploration and developments of artificial islands in the sea beach have strict demands in safety and environment protection. Thus higher requirements on the design of the artificial island are set forth. This article summarizes the key technology of artificial island design in Jidong oilfield which covers artificial island function, layout,construction standards, bottom protection measures for beach, dike structure, the island domain, reclamation and foundation treatment, external transport and the main aspects in artificial island design.
