【摘要】：地震勘探作为一种有效的地球物理勘探方法,已被广泛应用于煤田和工程地质勘察、区域地质研究和地壳研究等领域。地震勘探数据采集作业涉及勘探测线布置、采集装备布置、记录放线班报、布设炮点、激发震源、数据采集、数据回收等环节,需要使用采集设备和配套的地震勘探管理平台共同完成。通常,地震勘探管理平台需具备采集站和检波器管理、数据质量监控、触发管理、勘探信息管理、地震数据回收、地震数据预处理等功能。目前,市面上主流的地震勘探采集装备的管理平台已比较成熟,但却普遍存在以下缺点:1、无高可用性配置,存在单点故障隐患。勘探管理平台通常部署在一台计算机上,易出现设备故障问题,导致勘探作业中断,甚至勘探数据丢失。2、缺少勘探信息共享机制。通常,勘探作业的进度信息仅能由管理平台操作人员获取,并通过其他通信方式与测线上工作人员分享。3、大道距大数据量数据处理效率低下。获取地震数据后,需对原始数据进行预处理,获得单炮记录。随着地震勘探规模不断扩大,采集节点的增多,地震数据处理的计算量也越来越大,传统的计算模式已无法满足勘探需求。无缆自定位地震仪是吉林大学仪器科学与电气工程学院自主研发的地震勘探采集装备。具有野外布设便利,不受道数和距离限制,无需定位测量等特点,并支持多种模式的无线数据回传。但由于没有一套完整的地震勘探管理平台支持,无法良好地服务于地震勘探作业。针对以上问题,本文设计并开发了一套无缆自定位地震仪的勘探管理平台。该平台紧密结合地震勘探采集作业需求,并基于无缆自定位地震仪的特点进行开发。同时,针对目前其他平台普遍存在的缺点提出了解决方案。主要研究内容如下:1)研究地震勘探野外施工方法,基于无缆自定位地震仪设计并开发地震勘探现场控制模块。该模块具有勘探参数配置、采集站管理、地震数据质量监控、触发管理等功能。可配合无缆自定位地震仪完成地震数据采集任务。2)设计地震勘探信息发布模块。该模块基于JavaEE企业应用平台开发,以Web服务形式发布勘探进度信息,弥补了以往勘探管理平台缺少信息共享机制的不足,为作业人员及时掌握勘探信息提供便利。3)提出基于云计算的地震数据处理方法。该方法基于Hadoop大数据平台设计,用于处理原始地震数据,获得地震单炮记录文件。同时,使用HDFS(Hadoop分布式文件系统)存储地震数据,保证地震数据安全,满足大规模数据存储的需求。本文设计的地震勘探管理平台可满足无缆自定位地震仪独立完成地震勘探采集工作的需求,并且,加入信息共享和大数据处理及存储等模块,使地震勘探更加便利和高效,对无缆自定位地震仪的普及和推广具有重要的意义。
[Abstract]:Seismic exploration is an effective geophysical prospecting method has been widely applied in the coal and engineering geology, regional geological research and field research. The crustal seismic data acquisition operations involving the exploration line layout, equipment acquisition, recording line classes reported, gun laying excitation source, data acquisition, data recycling and other sectors, requires the use of acquisition equipment and supporting the seismic exploration management platform to complete. Typically, seismic exploration management platform required acquisition station and detector management, data quality control, trigger management, information management of geological exploration, seismic data recovery, seismic data preprocessing functions. At present, the mainstream market seismic acquisition the equipment management platform has been relatively mature, but generally has the following disadvantages: 1, no high availability configuration, the existence of hidden single point of failure. Exploration management platform is usually deployed in a meter On the computer, prone to equipment failure problems, resulting in exploration of interruption, even the exploration data loss.2, the lack of exploration information sharing mechanism. Usually, the progress of exploration operations can only obtain information management platform by the operator, and through other means of communication with the line staff to share.3 Avenue from the large amount of data processing the efficiency is low. After acquiring seismic data, need to preprocess the original data and get the single shot record. With the seismic exploration continues to expand the scale, increase the amount of calculation of seismic acquisition node, data processing is more and more big, the traditional computing model has been unable to meet the demand. Without cable self localization exploration seismograph seismic exploration acquisition equipment Jilin University School of Instrument Science and electrical engineering. With independent research and development of field layout is convenient, is not affected by the number and distance constraints, no characteristic measurement, and supports a variety of patterns The wireless data transmission. But due to the absence of a seismic exploration management platform to complete support, not good service in the process of seismic exploration. The exploration management platform to solve the above problems, this paper designed and developed a set of wireless self positioning seismograph. This platform combined with seismic exploration acquisition operation requirements, and no cable self locating earthquake the instrument was developed on the basis of characteristics. At the same time, in view of the common existing shortcomings of other platform solution is put forward. The main contents are as follows: 1) the field construction method in seismic exploration, wireless self positioning seismic instrument design and the development of seismic exploration field control module based on. The module has the exploration parameter configuration, acquisition station management. The seismic data quality monitoring, trigger management functions. With the wireless self positioning seismic instrument complete seismic data acquisition task.2) design of seismic information release module. This module The development and application of enterprise JavaEE platform based on the release of exploration progress information in the form of Web service, make up for the shortcomings of previous exploration management platform for the lack of information sharing mechanisms, to facilitate.3 workers to grasp the exploration information) method is put forward for seismic data processing based on cloud computing. The design of Hadoop big data platform based on the method for processing the original earthquake the data obtained, the seismic single shot records. At the same time, the use of HDFS (Hadoop distributed file system) storage of seismic data, seismic data to ensure safety, meet the massive data storage requirements. Seismic exploration management platform this paper designed can meet the wireless self positioning seismic instrument independently of seismic acquisition work demand, and add information sharing and data processing and storage module, the seismic exploration of more convenient and efficient, without cable self localization of seismic instrument and spread out It is of great significance.
