Drilling system suitable for ocean exploration drilling
The invention provides a drilling system suitable for marine exploration drilling, and belongs to the technical field of marine exploration drilling. The drilling system suitable for ocean exploration drilling comprises an offshore operation platform, an exploration brick well assembly, an adjusting assembly and a maintenance assembly. The damaged drill rod single body is separated from the lower drill rod single body, one holding piece holds the replaced drill rod single body, the other holding piece holds the damaged drill rod single body, and the damaged drill rod single body is separated from the upper drill rod single body; the positions of the replaced drill rod single bodies and the damaged drill rod single bodies are exchanged, the upper drill rod single bodies are connected to the replaced drill rod single bodies in a threaded mode, the replaced drill rod single bodies are connected to the lower drill rod single bodies in a threaded mode, the height of the drill rod needing to be lifted is effectively reduced through seabed maintenance operation, and the construction period of replacing the drill rod is greatly shortened; the traditional tedious process of lifting the drill rod to the water surface is replaced, and time and labor are saved.
本发明提供一种适用于海洋勘探钻井的钻井系统，属于海洋勘探钻井技术领域。该适用于海洋勘探钻井的钻井系统包括海上作业平台、勘探砖井组件、调节组件以及维修组件。本发明的损坏的钻杆单体和下方的钻杆单体分离，将一个抱合件抱合更换的钻杆单体、另一个抱合件抱合损坏的钻杆单体，损坏的钻杆单体和上方的钻杆单体分离，通过吊杆组和更换件的共同作用，将更换的钻杆单体和损坏的钻杆单体之间的位置交换，将上方的钻杆单体螺接于更换的钻杆单体，将更换的钻杆单体螺接于下方的钻杆单体，海底维修作业有效地减少了钻杆需要提升的高度，极大缩短更换钻杆的工期，取代了传统必须将钻杆提升至水面上的繁琐过程，省时省力。
