Sichuan region is a hydrocarbon bearing basin characterized by steep structure. Conventional migration method has limitations in prospecting steep structures, while equivalent velocity variable width diffration sweep migration method has advantages such as high efficiency, good image and higher signal-to-noise ratio. More resonable geology section can be pro- duced by using the forward model technique. Of course the migration be- fore stack remains the best migration method for steep structures.

四川是一个以陡构造著称的含油气盆地。用常规偏移方法研究该区陡构造有很大的局限性,而采用等效速度、变范围绕射扫描偏移方法,可以获得效率高、成像好、信噪比较高的效果。采用模型的正演技术,可以得到较为合理的地质剖面。当然,对于陡构造最好的偏移方法还是迭前偏移。

The effect analysis of processing the seismic data gathered from steep structures in Sichuan Basin by existent 1704 computer migration programs (e. g. Kirchhoff integral, finite difference, diffraction sweep and image ray depth migration methods etc.) Verifies that the combination of the equivalent velocity variable width diffraction sweep migration method and the forward model method makes a more ideal method for processing seismic data of complicated steep structures.
