【摘要】：大地电磁测深法是当今研究地球内部电性结构的一种重要的地球物理手段,在地质构造探测、地震的预报、石油天然气勘探、矿产普查和勘探、地质工程、地壳和上地幔电性结构研究和海洋地球物理等领域都发挥着重要作用。随着大地电磁三维反演理论的完善和计算机硬件的发展,三维反演慢慢的在实用化。由于三维反演程序运行平台与用户操作平台的差异,可能使操作反演程序变得复杂和困难。本文通过分析三维反演运行平台和用户运行平台之间的差异和三维反演的实际需求,设计和编写了与反演程序配套的反演数据远程操控模块,并实现了三维建模模块、数据准备模块、数据通讯模块和作业提交模块。使得用户能在Windows操作系统平台远程操控Linux端的三维MT反演程序的运行。本文中的三维建模模块,根据测点分布情况自动生成模型网格,网格大小以列表显示,用户可以对网格进行添加删减操作；电阻率模型分计算域和物理域显示,用户通过鼠标交互方式或输入数值来对模型进行电阻率赋值操作。数据准备模块,读取数据文件后将测点数据信息(坐标、视电阻率、相位等)进行显示,用户通过鼠标进行参与反演测点选取、参与反演数据选取等操作。同时,用户通过反演设置界面对反演进行详细设置。数据通讯模块,将常用反演操作命令进行了封装,连接了Windows与Linux,具有发送反演命令、接收反演情况和传输文件等功能。用户点击相对应的按钮即可实现包括反演开始、反演停止、反演删除和反演查看等功能。实现了在Windows操作系统平台远程操控Linux端三维MT反演程序的目的。作业提交模块,与三维MT反演程序一起部署于Linux端,基于PBS作业管理系统对多个用户提交的多个反演计算任务作业及对应数据文件进行管理,与数据通讯模块相配套,在Linux端接收反演相关操作命令后对反演任务进行相关操作,能同时运行多个反演任务而互相不影响,尽可能地利用计算集群性能。
[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.
