| The Seismic loading And Quality-Control system is the software scheme which is proposed to deal with the data missing, oversight and loading mistakes in the course of multiple seismic data gathering. Facing the seismic data volume and seismic data management departments, the output data stream of the system is directly used for the Seismic Data Management system. And the system plays an important role in the course of digitization construction and management of the domestic seismic data.The main content of the system is data analysis, control and management as the seismic data is loading, including the description and explanation information collection matching with the seismic data, the data loading and sorting according to the standard of seismic data management system, giving a preliminary evaluation on data quality, etc.In the course of study and development, the high-level Language C#, Visual Studio 2008 development environment,.NET framework are all used. In addition, MVC (Modal-View-Controller) model is used for system interface design, module design and process design, and Unified Modeling Language (UML) is also used to establish object-oriented model throughout the requirement and design in this paper. Considering the safety requirements of seismic data, the system uses the architecture development based on C/S, on which the main server and backup servers combine together and many management control nodes operate synchronously. High-speed links between server and client terminal is completed using fiber switches on LAN network configuration. Finally, the data quality control procedure is achieved including the two-dimensional seismic data processing, the three-dimensional seismic data processing, the seismic velocity data processing, universal functions, file system, help system. The coordinates extraction, navigation documents generating, navigation validation, C card reset, C card information input, CDP inspection, the trace serial number inspection, the trace identifier inspection, data volume analysis, data volume split and merger, trace header gone, seismic section shows, trace header extrication, speed format translation, data evaluation, matching script creation, the navigation data inspection, the seismic data inspection functions are realized throughout measurement results for quality control, seismic result data quality control, velocity data quality control, navigation and data matching relation control quality control points.As the system developed, the interdisciplinary theory research, model establishment and algorithm design has been done based on SEG-Y data in depth. Mostly, the module and algorithm of the seismic data trace reading, the two-dimensional seismic data navigation coordinate calculation, the three-dimensional seismic data navigation coordinate calculation are established and designed, which improves the application pattern and efficiency of the seismic data.In the actual application benefit aspect, the software thoroughly solves the high strength and error-prone issues in the seismic data quality control, and makes it batched, programmed and automatic. A large amount of historical data could be loaded, and the important information related could be added, so the value of the seismic data is promoted. The system has changed the seismic data control mode, in which the data is mainly processed manually. It improves the data accuracy with reducing cost at the same time. The system is innovative and practical because of combining with the development of the seismic database construction.At present, the software system passed the test and has been put into use. The effect is fairly good. The system is convenient and practical to use, which makes the seismic loading quality control workflow efficient, stable, safe, and reliable. The system greatly improves the effect of the seismic data of utilization and control. The software has certain space for development in function expanding and seamless links with the seismic data management system. |
