大洋钻探重入钻孔技术与系统发展应用

Development and application of the reentry drilling technology and system in ocean drilling

摘要:

通过对美国“格罗玛·挑战者号”、“乔迪斯·决心号”以及日本“地球号”大洋钻探船搭载的重入钻孔系统进行调研，介绍了大洋钻探重入钻孔技术现状、系统组成、工艺流程与应用。经过了大量实践验证的“挑战者号”和“决心号”上的重入钻孔系统和采用的重入方法是成熟可靠的，可为我国大洋钻探船的建造提供经验和借鉴。

Abstract:

In this paper, the reentry drilling systems on board of America’s “Glomar Challenger” drill ship, “JOIDES Resolution” drill ship and Japan’s “Chikyu” drill ship are investigated. This paper introduces the status of reentry drillingtechnology, the composition of the reentry drilling system, the process flow and application of reentrydrilling in ocean drilling. The reentry drilling system and the reentry method adopted on the “Challenger” and the “JOIDES Resolution” drill ship have been verified by a lot of practices, which may provide full reference for design and manufacture of the drill ship for China.
