Design Visualization In Marine Seismic Data Parallel Process System

At present, foreign major seismic data processing software: American WesternGeophysical’s Omega, LANDMARK company ProMax, Israel’s Focus and theFrench CGG; the domestic are: the oil GeoEast software Chuanqing geophysicalcompany GeoMountain system, Zhongyuan Oilfield PSI and Shengli OilfieldSeiWay systems.Most domestic universities and research institutes abroad Focus software withmassive seismic data processing, because the domestic seismic processing softwareis still not perfect, mature, particularly in dealing with massive data areas is slow,inefficient, while CNOOC developed MPS massive seismic data parallel processingsystem can processing huge amounts of data to improve the speed and efficiency, tomake up for the domestic software without dealing with massive data blank, thesystem can deal with huge amounts of data on land and at sea, to meet the currentseismic data processing for the accuracy and depth requirements, the software has avery good platform portability, in a unix/Linux/windows running on multipleplatforms.The thesis first introduces the hardware and software platform to build, as wellas the entire system development process. This software is a massive earthquake inthe MPS data parallel processing system based on the schema upgrade, to achievethe trace header keyword extraction, improved data display module, enhancedsystem stability and practicalityestablished a more efficient image interactionhandling mechanism, making CNOOC method for seismic processing resea rch andproduction system platform.Secondly introduced graphic images QT development tools and development kitsINT seismic data, there are two ways to achieve two-dimensional visualization ofseismic data, one is using QT image drawing mechanism will display seismic datanormalization and its interactive processing; another is the use of more maturedevelopment kit INT seismic data, the development kit can be directly read standardformat segy earthquake files, because this system is used in earthquake DHT format files, you need to use memory mapping incoming seismic data. This second methodis used with QT and INT build an efficient processing platform to improve theefficiency of oil and gas exploration, to get high-quality2D seismic data, seismicexploration personnel to facilitate the post-processing.This thesis having realized of the massive two-dimensional visualization ofseismic data, completed the seismic interaction process, not only to achieve aseismic trace editing, quality analysis, time-window rendering, and completed acomposite comparisons show gathers flip, density display and the color differentialdisplay, these interactions can be easily processed to obtain high-quality seismicexploration staff profiles, seismic interpretation so as to provide efficient and reliableseismic images.
