深水海底管线挖沟机的发展现状 张新明，梁富浩，田 帅 （海洋石油工程（珠海）有限公司，广东珠海 519050 ） 摘要：陵水17-2 自营深水气田勘探成功，将带动我国深水油气田的勘探与开发发展。挖沟是深水油气田开发中海 底管线的重要保护措施，我国目前研制与运营的挖沟机以浅水为主，通过分析现有深水挖沟机的发展现状，深水 挖沟机已发展成喷射式、犁式、机械式挖沟机，其核心技术集中在SMD、IHC EB 、FET 、Seatool、Nexans 等公 司，产品成系列化发展，由DeepOcean 、Saipem、Canyon Offshore、Nexans 等海洋工程公司运营，这将为我国深 水挖沟机技术及装备发展提供借鉴。 关键词：深水油气田；海底管线；喷射式挖沟机；犁式挖沟机；机械式挖沟机 The Development of Deepwater Trencher for Pipeline ZHANG Xinming, LIANG Fuhao, TIAN Shuai (Offshore Oil Engineering (Zhuhai) Co., Ltd., Zhuhai Guangdong, 519050, China) Abstract: The succeeded exploration of the Lingshui17-2 self-operated deepwater gas field, will promote the exploration and development of our deepwater oil gas oil. Trenching is one of important protected way for deepwater pipeline, our developed and operated trenchers were shallow-water ones. This paper focuses on analysis of the development of the deepwater trencher, which was developed water jetting, plough and mechanical cutting trenchers, its core technology was monopolized by the SMD, IHC EB, FET etc, and the parts of their products had been serialized. The trenchers are operated by the DeepOcean 、Saipem、Canyon Offshore、Nexans etc. This paper will support reference for the technology and equipment development for our deepwater trencher. Keywords: deepwater oil gas field, pipeline, water jetting trencher, plough, mechanical cutting trencher 中海油2002-2013 年间公布的海域开放区块153 个，其中南海占85%，42 个深水区（水深≥300m）全 [1] 部位于南海 ，尤其伴随2014 年9 月我国首次勘探成功自营陵水17-2 深水气田（作业水深1500m），我国 将加快南海深水及超深水油气田勘探与开发。海底管线是深水油气田开发中输送油气资源的重要设施，保 障海底管线运营安全，对整个深水油气田的安全生产都至关重要。挖沟是对深水海底管线保护的措施之一， 了解深水海底管线挖沟机发展现状对我国深水挖沟机的发展及我国深水油气田开发护航非常必要。 1 挖沟在深水海底管线保护中的应用 深水海底管线在海底处于复杂的海洋环境中，如海底水流、不
