摘要
截至2006年7月初,全球有103座深水半潜式钻井平台和33艘深水钻井船,它们主要分布于美国墨西哥湾、北海、巴西和西非海域。全球只有26家公司有能力从事深水钻井,其中美国公司最多,它们所拥有的深水钻井装置占全球总数的约70%。随着技术的进步,半潜式钻井平台和钻井船不断更新换代,额定作业水深和钻深能力相应增大。当前的钻井水深纪录和海上钻井井深纪录已分别达到3051米和10421米。半潜式钻井平台的钻深能力在6000～11430米,深水钻井船的钻深能力在5000～11887米。这两种在建钻井装置的钻深能力分别达到9000米或超过万米,并都采用动力定位方式。目前,国际市场上深水钻井装置供不应求,利用率接近或达到100%,最高日费已突破50万美元。国内的石油公司现在还没有深水钻井装置,这严重制约着我国三大石油公司进军深海的步伐,应引起有关部门的高度重视。
There were 103 semi-submersible and 33 submersible deep-water drilling vessels in the world by early July, 2006, located primarily in the Gulf of Mexico, the North Sea and offshore Brazil and West Africa. 26 companies are engaged in deep-water drilling, primarily from the US which accounts for about 70% of the world's deep-water drilling facilities. Continued technological advances are pushing the rated depth of underwater operation and drilling capacity to record highs. The current records for underwater depth and offshore drilling depth are respectively 3051and 10421 meters. Drilling depth capacities of semi-submersible platform are between 6000 and 11430 meters. Deep-water vessels can drill at a depth between 5000 and 11887 meters under water. The two dynamic-positioning drilling facilities under construction are designed to drill at a depth of 9000 meters and more than 10,000 meters under water. Deep-water drilling facilities are badly needed in the global market, with the day rate going to as high as 500,000 dollars. But Chinese oil companies still have no deep- water drilling facilities, lagging their expansion into the field of offshore oil development.
