Abstract: Bright spots technique is a effective seismic oil and gas testing technique and is a disputed technique in Petroleum Geophysics. This paper mainly introduces digital processing of seismic data and seven characteristics of bright spots profile as well as the limitation of the bright spots technique; According to actual data in Anzhuang area to make the reflect factor plate, it helps to interpret and analyze the bright spots technique and shows that it is a good assistant method to bright spots technique.
