深水钻井关键装备现状与选择

Status and Selection of Key Equipment for Deep Water Drilling

与陆地和浅滩相比,深水钻井海况环境更为复杂,对钻井装备和技术的要求更高。针对深水钻井的特点,对深水浮式钻井所需要的钻井装置、水下器具、水下井口等装备进行了阐述,分析了其发展现状、技术特点和关键参数,提出了选择这些装备应考虑的因素。

With the exhausting of onshore oil and gas resources, people begin to explore and develop new oil and gas resources in deep water and ultra deep water area. It requires more drilling equipment and drilling technologies due to the increased water depth and complicated marine conditions. According to the characteristic of deep water drilling, some key equipment is discussed in the paper, including the floating drilling equipments, subsea apparatus, suhsea wellhead. The factors that should be taken into account in equipment＇s selection are proposed on the bases of the analysis of the equipment＇s development status, technical characteristic and key parameters.
