【摘要】 长期以来,准噶尔盆地石南地区地震资料分辨率较低,无法满足岩性油气藏勘探的要求。针对准噶尔盆地石南地区原始地震资料的特点,提出采集阶段提高对地震波场的空间采样密度,并通过高覆盖次数改善资料信噪比;处理阶段解决好静校正,应用F-XYO域预测去噪技术、动校正考虑各向异性问题,通过合理流程提高分辨率处理。通过采集处理一体化解决方案的实施,在提高地震资料分辨率方面取得了明显效果。更多还原

【Abstract】 The resolution of seismic data was low in Shinan Area of Jungar Basin, it could not satisfy the demands of lithologic reservoir exploration. In allusion to the characteristics of Jungar Basin, it was proposed that the density of space sampling was improved for seismic field at the stage of acquisition, its signal-noise ratio was improved by higher coverage and static correction was implemented effectively during the process of noise removal was predicted with F-XYO. Anistropic correction was involved in dynamic correction, and a rational flow chart was used to improve resolution. It is implemented by the integration of data acquisition and processing, by which obvious result is obtained for improving the resolution.更多还原
