摘要：

利用转换波（P-SV)的传播速度比纵波低，传播不受孔隙流体的影响，传播规律和纵波有较大的区别，可以进行有效的油气识别。针对鄂尔多斯盆地储层以陆相中的三角洲平原分流河道砂体为主，储层分布变化大，横向上低孔低渗，储层物性的非均质性比较强，P-SV波资料处理与P波资料处理有一些差异的特征,对SLG气区实际3D-3C地震资料处理中的转换波静校正问题、共转换点（CCP）道集抽取方法、转换波的速度分析方法、动校正方法及转换波和纵波比例压缩方法等进行了研究，建立了3D-3C地震资料处理方法和技术，并取得了良好的应用效果，可以将该方法在实际生产中推广应用。

Abstract:

Converted shear wave （P-SV） has lower velocity than P wave and its propagation is not influenced by pore fluid.The propagation regularity of converted wave is very different from that of P wave and this difference can be used to effectively identify oilgas.The reservoirs are mainly sandstone bodies of deltaic plain distribution channel in Ordos Basin and its distribution changes rapidly with low pore and low permeability laterally.Heterogeneity of reservoir physical property is apparent.In processing of real 3D converted wave seismic data in SLG gas province，researches are concluded in static sorting of common converted point （CCP） gathering，velocity analysis，NMO，etc..The 3C-3D seismic data processing flow chart is finally built and it is suggested that this processing flow chart may be widely used in converted shear wave seismic data processing.

Key words: converted shear wave, 3D-3C seismic data, SLG gas province, CCP（common converted point）, converted wave static correlation 
