Abstract: GeoEast-Lightening VI.0 software is one-way wave equation pre-stack depth migration software system designed to meet oil and gas exploration and development demand and facilitate a large-scale calculation on cluster with interactive job management. Its RMT function can be operated on GPU-CPU heterogeneous multi-core clusters for 2D and 3D seismic data imaging. It has been widely used in exploration of oil and gas resources. To meet the demand for seismic imaging technology for increasingly complicated oil and gas exploration and break international technological blockage, BGP started to develop “GeoEast-Lightening wave equation pre-stack depth migration software” in 2009 for the purpose to develop RMT software with independent intellectual property right. This software takes the lead in realizing large-scale application and industrialization of RMT in China. This technology reached international advanced level of its kind, with some technological targets leading the world in this area.

Key words: RTM, oil and gas exploration

摘要： GeoEast-LightningV1.0软件是一款为了满足油气勘探和开发需要而研制的,能够适应大规模并行机群,交互式作业调度管理的单程波、逆时叠前深度偏移软件系统,其逆时偏移功能可在GPU-CPU异构多核集群上运行,适用于大规模二维、三维地震资料成像处理,在油气田资源勘探过程中能够得到广泛应用。为增强自主创新能力和核心竞争力,满足油气勘探复杂程度日益增大对地震成像技术的需求,突破国际技术封锁,开发具有自主知识产权的逆时叠前深度偏移软件填补国内空白,东方地球物理公司于2009年开始了"GeoEast-Lightning波动方程叠前深度偏移软件"的研发。该软件率先实现了逆时偏移技术在国内的规模化和工业化应用,整体技术达到国际同类先进水平,部分技术指标达到国际领先水平。
