【摘要】：在野外的地震勘探作業(yè)中,勘探儀器采集的地震數(shù)據(jù)一般都存儲在磁帶介質(zhì)上,然后把磁帶需要運送到數(shù)據(jù)處理中心,進行分析和處理。作為數(shù)據(jù)交換、存儲介質(zhì)的磁帶發(fā)揮著不可或缺、巨大的作用并被大量地使用于石油天然氣勘探行業(yè)。磁帶介質(zhì)和設備的管理能力已經(jīng)成為地震數(shù)據(jù)處理系統(tǒng)的一個重要衡量標準。為了加強國內(nèi)石油天然氣的勘探開發(fā),川慶物探公司開設GeoMountain軟件研發(fā)項目,本項目是其中重要的子系統(tǒng)。 本文首先調(diào)研當前國內(nèi)國際上主流的磁帶設備管理系統(tǒng),研究了Linux平臺下對設備的管理方法及對磁帶設備的讀寫技術,分析了地震數(shù)據(jù)的格式、在磁帶上的存儲方法和地震數(shù)據(jù)處理方法,使用QT的圖形框架和網(wǎng)絡框架,在此基礎上設計和實現(xiàn)了分布式磁帶資源管理系統(tǒng)。 分布式磁帶管理系統(tǒng)包含中央控制服務器、磁帶機設備代理、操作員控制臺、管理員控制臺等模塊以及通信協(xié)議。通信協(xié)議規(guī)定了本系統(tǒng)中各個模塊中進行通信的數(shù)據(jù)格式以及在發(fā)送或接收數(shù)據(jù)時采取的動作；中央控制服務器管理整個系統(tǒng)的資源,控制設備的分配,控制本系統(tǒng)中的其它模塊,協(xié)調(diào)整個系統(tǒng)的運行；磁帶機設備代理實現(xiàn)對本機掛載的磁帶機執(zhí)行具體操作,包含讀寫和控制,向中央控制服務器報告自身的狀態(tài)；操作員控制臺為用戶提供一個交互可視化的操作界面,實現(xiàn)對磁帶的讀寫操作、對磁帶機的控制操作、可視化顯示地震數(shù)據(jù),顯示日志信息等；管理員控制臺為管理員提供一個圖形界面化的管理工具,管理系統(tǒng)中的用戶、日志和設備信息。 通過本項目的研發(fā),形成一套性能良好、穩(wěn)定的磁帶設備和磁帶/磁盤介質(zhì)整合管理系統(tǒng),更好地為實際生產(chǎn)服務,從而有利促進GeoMountain軟件的商業(yè)推廣,進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.
