【摘要】：大地電磁測深法是當(dāng)今研究地球內(nèi)部電性結(jié)構(gòu)的一種重要的地球物理手段,在地質(zhì)構(gòu)造探測、地震的預(yù)報、石油天然氣勘探、礦產(chǎn)普查和勘探、地質(zhì)工程、地殼和上地幔電性結(jié)構(gòu)研究和海洋地球物理等領(lǐng)域都發(fā)揮著重要作用。隨著大地電磁三維反演理論的完善和計算機(jī)硬件的發(fā)展,三維反演慢慢的在實用化。由于三維反演程序運(yùn)行平臺與用戶操作平臺的差異,可能使操作反演程序變得復(fù)雜和困難。本文通過分析三維反演運(yùn)行平臺和用戶運(yùn)行平臺之間的差異和三維反演的實際需求,設(shè)計和編寫了與反演程序配套的反演數(shù)據(jù)遠(yuǎn)程操控模塊,并實現(xiàn)了三維建模模塊、數(shù)據(jù)準(zhǔn)備模塊、數(shù)據(jù)通訊模塊和作業(yè)提交模塊。使得用戶能在Windows操作系統(tǒng)平臺遠(yuǎn)程操控Linux端的三維MT反演程序的運(yùn)行。本文中的三維建模模塊,根據(jù)測點分布情況自動生成模型網(wǎng)格,網(wǎng)格大小以列表顯示,用戶可以對網(wǎng)格進(jìn)行添加刪減操作；電阻率模型分計算域和物理域顯示,用戶通過鼠標(biāo)交互方式或輸入數(shù)值來對模型進(jìn)行電阻率賦值操作。數(shù)據(jù)準(zhǔn)備模塊,讀取數(shù)據(jù)文件后將測點數(shù)據(jù)信息(坐標(biāo)、視電阻率、相位等)進(jìn)行顯示,用戶通過鼠標(biāo)進(jìn)行參與反演測點選取、參與反演數(shù)據(jù)選取等操作。同時,用戶通過反演設(shè)置界面對反演進(jìn)行詳細(xì)設(shè)置。數(shù)據(jù)通訊模塊,將常用反演操作命令進(jìn)行了封裝,連接了Windows與Linux,具有發(fā)送反演命令、接收反演情況和傳輸文件等功能。用戶點擊相對應(yīng)的按鈕即可實現(xiàn)包括反演開始、反演停止、反演刪除和反演查看等功能。實現(xiàn)了在Windows操作系統(tǒng)平臺遠(yuǎn)程操控Linux端三維MT反演程序的目的。作業(yè)提交模塊,與三維MT反演程序一起部署于Linux端,基于PBS作業(yè)管理系統(tǒng)對多個用戶提交的多個反演計算任務(wù)作業(yè)及對應(yīng)數(shù)據(jù)文件進(jìn)行管理,與數(shù)據(jù)通訊模塊相配套,在Linux端接收反演相關(guān)操作命令后對反演任務(wù)進(jìn)行相關(guān)操作,能同時運(yùn)行多個反演任務(wù)而互相不影響,盡可能地利用計算集群性能。
[Abstract]:Magnetotelluric sounding is an important geophysical means to study the electrical structure of the earth's interior. It plays an important role in geological structure detection, earthquake prediction, petroleum and natural gas exploration, mineral prospecting and exploration, geological engineering, crust and upper mantle electrical structure research and marine geophysics. The three dimensional inversion theory is perfect and the computer hardware is developed, and the three-dimensional inversion is gradually practiced. Because the difference between the three dimensional inversion program running platform and the user operating platform, the operation inversion may be complicated and difficult. This paper analyzes the difference between the three dimensional inversion operation platform and the user running platform and the three dimensional inverse. The actual demand, design and write the remote control module of inversion data matching with the inversion program, and realize the 3D modeling module, the data preparation module, the data communication module and the operation submission module. The user can operate the 3D MT inversion program of the Linux end remotely in the Windows operating system platform. Model module, the model grid is automatically generated according to the distribution of measuring point. The size of the grid is displayed in list. The user can add and delete the grid. The resistivity model is divided into the calculation domain and the physical domain. The user uses the mouse interaction mode or the input value to perform the operation of the electrical resistance rate. The data preparation module is used to read the data. After the file, the data information (coordinates, apparent resistivity, phase, etc.) is displayed. The user participates in the selection of the inversion point and participates in the inversion data selection through the mouse. At the same time, the user sets the inversion through the inversion setting interface in detail. The data communication module encapsulates the commonly used inversion operation commands and connects Window S and Linux have the functions of sending inversion commands, receiving inversion conditions and transmitting files. Users click the corresponding button to implement functions such as inversion start, inversion stop, inversion deletion and inversion view. The purpose of remote control of Linux terminal 3D MT inversion program on the Windows operating system platform. The 3D MT inversion program is deployed at the Linux end together. Based on the PBS job management system, it manages multiple retrieval tasks and corresponding data files submitted by multiple users. It is matched with the data communication module. After receiving and inversion of relevant operating commands at the Linux side, the inversion tasks are operated and multiple inversion tasks can be run at the same time. Do not affect each other and make use of computing cluster performance as much as possible.
