Abstract: The eighth member of Shihezi Formation is a major reservoir of Sulige gas field in Ordos Basin. It is a thin reservoir of low porosity and permeability, so it is hard to be predicted based on regular seismic prediction. Multi-wave exploration technique could be used to improve accuracy of rock character and fluid property by adding with S-wave data. This paper focuses on multi-wave application in Sulige gas field, mainly discusses converted wave static correction, converted wave imaging, fine PS wave calibration, P and S joint interpretation, joint inversion, and thus better solves difficulties in converted imaging. Meanwhile, the success ratio of drilling is improved greatly by using the fluid detection methods based on multi-wave AVO and multi-wave joint inversion. This paper presents a set of reservoir prediction methods of multi-wave fluid detection focusing on western area of Sulige, which are proved to be feasible in the area

Key words: converted wave static correction, pre-stack time migration, full wave attributes, joint inversion, Sulige gas field
