【摘要】：在野外的地震勘探作业中,勘探仪器采集的地震数据一般都存储在磁带介质上,然后把磁带需要运送到数据处理中心,进行分析和处理。作为数据交换、存储介质的磁带发挥着不可或缺、巨大的作用并被大量地使用于石油天然气勘探行业。磁带介质和设备的管理能力已经成为地震数据处理系统的一个重要衡量标准。为了加强国内石油天然气的勘探开发,川庆物探公司开设GeoMountain软件研发项目,本项目是其中重要的子系统。 本文首先调研当前国内国际上主流的磁带设备管理系统,研究了Linux平台下对设备的管理方法及对磁带设备的读写技术,分析了地震数据的格式、在磁带上的存储方法和地震数据处理方法,使用QT的图形框架和网络框架,在此基础上设计和实现了分布式磁带资源管理系统。 分布式磁带管理系统包含中央控制服务器、磁带机设备代理、操作员控制台、管理员控制台等模块以及通信协议。通信协议规定了本系统中各个模块中进行通信的数据格式以及在发送或接收数据时采取的动作；中央控制服务器管理整个系统的资源,控制设备的分配,控制本系统中的其它模块,协调整个系统的运行；磁带机设备代理实现对本机挂载的磁带机执行具体操作,包含读写和控制,向中央控制服务器报告自身的状态；操作员控制台为用户提供一个交互可视化的操作界面,实现对磁带的读写操作、对磁带机的控制操作、可视化显示地震数据,显示日志信息等；管理员控制台为管理员提供一个图形界面化的管理工具,管理系统中的用户、日志和设备信息。 通过本项目的研发,形成一套性能良好、稳定的磁带设备和磁带/磁盘介质整合管理系统,更好地为实际生产服务,从而有利促进GeoMountain软件的商业推广,进一步提升物探公司的地震勘探能力。
[Abstract]:In the field seismic exploration, the seismic data collected by exploration instruments are usually stored on tape medium, and then the tape needs to be transported to the data processing center for analysis and processing. As data exchange, magnetic tape of storage medium plays an indispensable role and is widely used in oil and gas exploration industry. The management ability of magnetic tape media and equipment has become an important measure of seismic data processing system. In order to strengthen the exploration and development of domestic oil and gas, Chuanqing Geophysical Exploration Company has set up GeoMountain software research and development project, which is one of the important subsystems. In this paper, the current mainstream tape equipment management system at home and abroad is investigated, the management method of equipment and the reading and writing technology of tape equipment under Linux platform are studied, and the format of seismic data is analyzed. Based on the storage method on tape and the seismic data processing method, the distributed tape resource management system is designed and implemented based on the graphic framework and network framework of QT. Distributed tape management system includes central control server, tape drive device agent, operator console, administrator console and communication protocol. The communication protocol specifies the data format of the communication in each module of the system and the actions taken when sending or receiving the data. The central control server manages the resources of the whole system, controls the allocation of the equipment, controls other modules in the system, and coordinates the operation of the whole system. The tape drive device agent implements the specific operation on the mounted tape drive, including reading, writing and controlling, and reports its own status to the central control server. The operator console provides users with an interactive visual operation interface to realize the reading and writing operation of the tape, the control operation of the tape drive, the visual display of seismic data, the display of log information and so on. The administrator console provides administrators with a graphical interface management tool to manage user, log, and device information in the system. Through the research and development of this project, a set of good performance and stable tape equipment and tape / disk media integration management system has been formed, which can better serve the actual production, so as to promote the commercial promotion of GeoMountain software. Further improve the seismic exploration capability of Geophysical Exploration Company.
