海洋深水钻井技术研究

Studies on Offshore Deep-water Drilling Technology

在过去10年,尽管深水勘探和开发工作大规模开展,但到目前为止,深水钻井仍是一个不成熟的前沿领域。介绍了目前深水钻井的一些主要难题,指出了深水钻井面临的挑战,并对解决深水钻井难题的方法进行了探索。根据国外深水钻井的经验,提出了双梯度深水钻井及膨胀管技术等适合深水钻井的技术方法,并对适合深水钻井的钻井液体系进行了研究。

In the past ten years, deep-water E & P was conducted on a large-scale. But until now, deep-water drilling is still an immature and front domain. In this paper, the main difficulties in deep-water drilling are illustrated, the challenges are pointed out and the solutions to drilling problems are also explored. Base on drilling experiences from abroad, the dual gradient drilling and expandable tubulars technologies, which are suitable for deep-water drilling, have been presented. The drilling fluid system suitable for deep-water drilling has also been studied.
