Application of seismic attributes in the prediction of deep reservoirs in Anpeng region

Seismic data sets contain abundant subsurface geological information. Seismic attributes are related to geology, and can be effectively used in reservoir prediction. This paper discussed the geologic meaning of various seismic attributes and extracted attributes such as amplitude,frequency, and attenuation on He the third member sandstone segments Ⅴ of Ⅵ and in Anpeng. The reflections of segment Ⅴ were characterized by good continuity,strong amplitude, low frequency and sharp attenuation of energy, and can be classified as bright spot reservoir. The reflections of segment VI were characterized by poor continuity, weak amplitude, and high frequency, and can be classified as dim spot reservoir. The results were confirmed by drilling.
