| Abstract: | To solve the problem of multi-wave seismic imaging, we adopt a few approaches such as converted wave static correction, multi-wave velocity joint analysis, and consistent processing techniques for multi-wave data processing in Sulige Gas Filed. Multi-wave data imaging is greatly improved. Based on petrophysical analysis, we use multi-wave AVO analysis, multi-wave joint prestack inversion, and cross plot technique to perform reservoir prediction. The results show that our approaches can greatly improve reservoir prediction and reduce multiple solutions of prediction with only P-wave. |
