辽河油田海南8区块海工建设

Offshore Engineering Construction at Liaohe Oilfield Hainan-8 Block

辽河油田海南8区块位于辽东湾海域,根据该海域涨潮满水、落潮为滩、冬季固定冰、流冰共存的实际情况,研究开发了辽河油田海南8区块海底管道和砂石人工岛建设新技术,并建成了中石油第一条海底混输管道和国内第一座不与陆地相连的砂石人工岛。文章概述了海南8区块海底管道和砂石人工岛的工程环境及结构特点,重点介绍了工程建设采用的各项新技术。

Liaohe Oilfield Hainan-8 Block is located in Liaodong Bay. Considering the special sea conditions of being water area in flood tide and shoal in ebb tide as well as coexisting fast ice and moving ice in winter, a new offshore construction technology of subsea pipeline and artificial sand-stone island was developed for Hainan-8 Block. The first subsea multi-phase transmission pipeline and the first artificial sand-stone island isolated from land in China were built. This paper introduces briefly the engineering environment and structural characteristics of the subsea pipeline and the artificial island at Hainan-8 Block, and puts the emphasis on the new techniques applied for the engineering project construction.
