摘要
吐哈盆地现有的以各三维区块拼接为主的区域性地震资料品质差异大,难以满足区域整体研究的需要。基于GeoEast系统,开展吐哈探区环胜北洼陷20块三维地震资料整体融合处理,运用微测井约束层析反演静校正技术、叠前保真组合去噪技术、子波一致性处理技术、面元均一化处理等,较好地消除了不同区块资料间的差异,有效提高了地震资料品质,为区域整体评价研究提供了可靠的数据基础,同时充分展示了GeoEast系统具有盆地级地震资料连片融合处理的强大功能。
The quality of available regional seismic data in the Tuha Basin,mainly spliced by the data of three-dimensional(3D)blocks,varies greatly,which can hardly meet the needs of overall regional research.Therefore,we use the GeoEast system to carry out the merging processing of three-dimensinal(3D)seismic data of 20blocks in Shengbei Sag of the Tuha exploration area.We employ the static correction technique for tomographic inversion constrained by uphole surveys,wavelet consistency processing technology,true pre-stack combined denoising technology,bin averaging technique,etc.These techniques can well eliminate the differences between seismic data from different blocks,improve the quality of seismic data,and provide technical support for overall regional evaluation research.The research also shows that the GeoEast system has a powerful function of merging processing for basin-level seismic data.
