高分辨率处理技术在松辽盆地中、浅层岩性油藏勘探中的应用

在分析了影响高分辨率处理的主要环节的基础上，探讨了高分辨率处理中需要解决的几个关键问题，给出了一套实用的高分辨率处理技术；重点阐述了合理利用叠前去噪、振幅恢复、组合反褶积和多次剩余静校正等处理方法提高地震资料分辨率的技术问题。在实际地震资料处理的成果剖面上，各反射层位的波组特征清楚，层间信息丰富，波形自然稳定。与老剖面相比，利用高分辨率处理技术所得到的地震剖面在分辨率、信噪比、波形特征等方面都有明显改进，能够较好地满足地震资料解释的要求，表明这套高分辨率处理技术具有推广应用价值。

Application of high resolution processing technique in middle-shallow lithologic reservoirs of Songliao Basin

This paper discusses several key problems need to be solved in high resolution processing based on analyzing the main effecting factors in high resolution processing and puts forward a set of practical high resolution processing technique.The focal point is to expound processing methods including reasonably remove noise before stack,amplitude recovery,combination deconvolution and multiple residual correction to improve the resolution of the seismic data. In practical seismic data processing achievement profile,wave group characteristics of every reflection zone are clear,information of layer to layer is rich and wave shape is natural and stable.Compared with old profile,resolution,signal to noise ratio,wave characteristics achieved in seismic profile of high resolution processing technique is improved obviously,which could better fulfill the requirement of the seismic data interpretation. This shows that this set of high resolution processing technique has a value of popularizing and application.
