| Abstract: |
| Seabed Drill Rig, for its advantage of low cost, high efficiency, small disturbance of core sample, easy to keep pressure, small size, easy to operate and good ship adaptability, etc. has became an important technical equipment of seabed resource exploration, geological survey and scientific investigation, and also gained attention and application of all marine power country. Combined with its development and application, around four generation of seabed drill rig were summarized and analyzed as the evaluation criteria of water depth, drilling depth, coring methods, multi-function, intelligent, etc. and some representative drill rigs also were described in detail. And at last, five development trends were put forward from drill depth and core diameter, multi-mode drilling and coring way, intelligent monitoring of equipment status, multi-monitoring of downhole and wellhead, support system and deck suitability, etc. |
| Key words: seabed resource exploration drill rig status development. |
