摘要
海上三维地震资料处理是海上石油勘探开发的一个重要环节。在油田开发中,为满足储层研究对三维资料高分辨率、高信噪比的要求,必须提高三维处理的技术水平,改善成果资料的质量。本文着重介绍了海上三维资料处理中的几个关键技术问题的解决以及处理效果文中首先介绍了海上三维工作中特有的问题,覆盖次数不匀的影响以及解决办法和效果;其次讨论了空间采样的影响以及道内插技术的应用;然后介绍了三维偏移速度的建立方法及其效果,以及一步法偏移的效果;最后对如何提高处理成果资料的分辨率问题进行了分析讨论。
The marine 3-D seismic data processing is considered a key link in offshore exploration and development as well. In the coures of oil development, the technical competence in
3 - D data processing and quality of final presentation must be increased and improved for ensuring high resolution and high S/N which are supposed to be the MUST for reservoir studies . The stress of the paper is laid on how to solve the key problems come across in marine
3-D data processing and its processed results.
Problems peculiar to offshore 3-D survey, such as influence resulted from randomly-laid
out fold coverage, the solution for it and its positive effect produced are. in the first place, expounded; next, to discuss the affect caused by spatial sampling and application of trace interpolation technique; and then what's brought out is the approach of and effect from developing 3-D migration velocity and migrated result from one - step approach; at last, the way how to enhance the resolution of the resulting data processing is examined and deliberated over.
