摘　　要：在墨西哥湾大陆架外深水区域的水下存在大量的油气资源,在钻探过程中遇到了完全不同于以往的技术障碍,产层被分布广泛的巨厚盐层所覆盖,对通常采用的钻井和完井技术是一个巨大的挑战。对如何利用先进的钻井工具、工艺和钻井液管理方法解决巨厚盐层带来的钻井难点进行了论述,探讨了如何在满足深水开发的特殊经济和技术需求的同时实现上述目标。墨西哥湾地区已经完成了盐下远景区的勘探工作,目前已进入开发和生产阶段。There are abundant oil and gas resources underwater in the deepwater areas outside the continental shelf in the Gulf of Mexico. During the drilling and exploration, the technical obstacles encountered were completely different from those previously met. These production layers are covered by the widely distributed and tremendously thick salt beds, posing a great challenge to the common drilling and completion technologies. How to make use of advanced drilling tools, processes and drilling lfuid management methods to settle the drilling dififculties due to the tremendously thick salt beds has been expounded, and how to meet the special economic and technical requirements of deepwater development while realizing the abovementioned goals has been discussed. The perspective explo-ration below the under-salt has been ifnished in the Gulf of Mexico. Currently, it has entered the development and production stages.
