胜利油田滩海潜堤施工技术

胜利油田滩海地区是油田产油的重点区域。近年来,由于黄河来水锐减,致使海岸线蚀退,海水严重浸入海岸线,对胜利滩海油田海堤的安全造成了极大的威胁。因此,防止海岸线蚀退,已列为中国石化集团重大科技攻关课题。文章根据胜利油田滩海地区特殊的施工环境,结合多年在滩海潮间带的施工经验,提出了3种施工方案,即板桩直立墙式潜堤结构施工、双排管桩内外侧抛石堤结构施工和抛石堤上平铺FS浆垫结构施工,并着重对双排管桩内外侧抛石堤结构进行了详细的介绍,为治理胜利油田滩海地区海岸线蚀退积累了宝贵的经验,可供相关的工程技术人员借鉴。

Research on Construction Technique of Submersible Sea Bank in Shengli Oilfield

The beach area of Shengli Oilfield is an important oil production reg ion. In recent years, the flow capacity of Yellow River has been decreasing sha rply, so that the coastline is set back owing to erosion. It brings severe thre at to the oilfield bank safety. To prevent coastline from erosion has been a maj or research subject of CINOPEC. Based on the especial construction environment a nd in combination with the construction experiences in this beach area, this pa per puts forward three structural construction schemes, i.e. sheet pile standin g wall sea bank, double rows of pipe piles with both sides of riprap, and ripr ap bank with FS grouting mat. And the structure of double rows of pipe piles wit h both sides of riprap is described in detail. The valuable experiences for prot ecting coastline from erosion in the beach area of Shengli Oilfield are accumula ted.
