介绍了中海油田服务股份有限公司在中国南海进行的预试井活动,讨论了将用于深水油田钻井作业的人工海底新技术.深水钻井市场在最近10年中处于不断扩张的过程,目前世界上用于深水和超深水钻采作业的钻井船和平台数目不足.中国目前也需要更多的设备用于深水海洋的钻采作业.中海油田服务股份有限公司目前拥有的一些半潜式钻井平台可以在水深浅于475m的水深中进行作业.自从2004年以来,中海油田服务股份有限公司与挪威公司合作,进行人工海底技术的研究和改进,这种技术发展的目标是,利用较浅水作业的钻井平台,进行水深1000～1500m的油气田的钻井作业.介绍了该种技术研究和改进的过程,相关装备的生产和更新.2008年6月,在中国南海的500m水域应用人工海底技术进行了预试验井的作业.2009年,中海油田服务股份有限公司将在中国南海的同一海域进行另一次更深入的实际钻井作业.
This paper introduces the pre-well drilling activities undertaken by China Oilfield Services Co., Ltd. in the South China Sea and discusses the new artificial seabed technology to be used in drilling operations in deep-water oil fields. The market for deep-water drilling has been expanding continuously in the recent 10 years. At present, The number of drilling vessels and platforms used for deepwater and ultra-deep-water drilling operations is not enough, and China now needs more equipment for deepwater drilling. Some of the semi-submersible drilling rigs now owned by China Oilfield Services Co., Ltd. Operating at depths less than 475 m. Since 2004, China Oilfield Services Limited, in cooperation with the Norwegian company, has conducted research and improvements on artificial seabed technology, which has been developed with the goal of drilling with shallower water Platform to carry out drilling operations of oil and gas fields with water depth of 1000 ~ 1500m, introduces the research and improvement process of this kind of technology, and the production and renewal of related equipment.In June 2008, pre-test was carried out in 500m waters of South China Sea using artificial seabed technology Well operations. In 2009, China Oilfield Services Co., Ltd. will conduct another in the same area of the South China Sea More in-depth actual drilling operations.
