| 摘 要： | 深海油气开采是高风险、高投资、高技术、高回报的行业。我国南海海域石油储量巨大，属于世界四大海洋油气富集区之一，其中70%储藏于深水区。南海深水钻井面临的主要挑战是:浅层气和浅层流、深水低温、深水井控技术、缺乏深水作业经验和南海的灾害环境，在分析这些挑战可能造成的危害的基础上，从浅层流控制措施、钻井液优选、水泥浆优选、深水钻井井控措施、建立台风应急预案等方面，给出了技术对策。以2006年在南海钻成的作业水深1 481 m的LW3-1-1井为例，详细介绍了深水钻井施工情况。

| Abstract: | Deepwater oil and gas exploration is a high risk,high investment,high technology,high-return business.South China Sea has huge oil & gas reserves and belongs to one of the four major offshore oil and gas rich region in the world,of which 70% is in deep water.There are several challenges in deepwater drilling in South China Sea,such as shallow gas & shallow flow,deep water and low temperature,deep water well control technology,the lack of deepwater operating experience and South China Sea environmental disas... |
