基于人工地震剖面的深地测深数据库建设

Construction of deep seismic sounding database based on artificial seismic profile

深地测深数据库是根据人工地震剖面,以科学大断面为数据基础,综合物理勘探方法,并充分吸收历年成果资料,应用新技术、新理论和新方法编制而成。深地测深数据库内容丰富,信息量巨大,数据约3 TB,记录了1976—2016年131条人工地震剖面,观测距离34455 km,炮点个数825个,观测点数60374个。各剖面均建立相应属性,并编写数据库说明书和元数据。数据库采用统一编号和格式,编写过程采用SQL平台工作站完成,数据精度高,质量好,符合设计要求。深地测深数据库充分反映了人工地震多年的研究成果和当前研究的新水平。

Deep seismic sounding database is compiled based on the data of artificial seismic sections and scientific large sections by integrating physical exploration methods,fully absorbing the achievements of the work over the years,and using new technologies,new theories,and new methods.The deep seismic sounding database is rich in content and has a huge amount of information,with about 3 TB of data consisting of 131 artificial seismic profiles from 1976 to 2016,with observation distance of 34455 km,number of shot points of 825,and observation points of 60374.For each seismic profile,corresponding attributes are established,and database specifications and metadata are compiled.The database adopts unified numbering and format,and the preparation process is completed based on the SQL platform.The data has high precision and good quality,which meets the design requirements.The deep seismic sounding database fully reflects the research achievements of artificial seismic for many years and the new level of research at present.
