国内外天然气水合物的研究目前集中于勘探、开采等技术层面,对天然气水合物数据库研究的报道较少.天然气水合物勘探开发是一个综合多门学科的技术,涉及地球物理、地球化学、沉积学、热动力学、环境科学等学科,各个学科之间交叉性强.野外调查获取的数据异常复杂,数据之间具有很强的关联性,因此,如何建立一个综合多门学科的统一的水合物空间数据库结构成为一个亟待解决的问题.设计了一套面向勘探开采的天然气水合物数据库结构,数据库结构在广州海洋地质调查局天然气水合物数据实际存储过程中得到有效验证.为天然气水合物数据的进一步挖掘研究提供有效保障.“,”At present,the work around natural gas hydrate is mainly focused on geological survey and exploration.Only has little attention been paid to database construction.However,the exploration of natural gas hydrate is a integrated technological endeavor containing geophysical,geochemical,sedimentological,geological,geothermal dynamics,environmental scientific studies.Due to the complex of the data and the strong interrelationship among them,how to manage the data has become a big challenge in front of us.To solve this problem,this paper proposed a new database construction scheme to manage the gas hydrate data obtained from the survey in the South China Sea.The use of the construction is proved successful for Guangzhou Marine Geological Survey.
