Drilling Technology Status and Development Trends of Deep-sea Seafloor Drill
Subsea drilling and coring is the critical technology necessary to carry out marine geological and environmental scientific research,marine mineral resources exploration,and subsea engineering geological survey,and seafloor drill is the most promising technical equipment for deep-sea drilling.First,the existing technical characteristics and drilling cases of several major deep-sea seafloor drills in the world are described;Then,a systematic summary of the technical characteristics of Chinese deep-sea seafloor drills and the application of drilling and coring rigs in four stages:deep-sea seafloor shallow strata drill,deep-sea seafloor medium-deep strata drill,deep-sea seafloor deep strata drill,deep-sea seafloor ultra strata drill;Finally,the development trend and challenges faced by deep-sea seafloor drills are analyzed.These deep-sea seafloor drills are anticipated to evolve towards ultra-deepwater,ultra-deep drilling,high quality,and multi-functionality,while also encountering challenges in materials,sealing,support,and retrieval.A comprehensive review of the technical characteristics and current status of deep-sea seafloor drills domestically and internationally will provide a reference for the design and research of future deep-sea seafloor drills.
