The attribute of seismic frequency spectrum decay can reflect the formations'absorption property、litho-facies and gas-bearing property.Making use of the gas-bearing formations'characteristic that can absorb the high frequency energy of seismic wave easily,we can predict gas reservoir in formations better.The Cretaceous exploration area in oil and gas has been expanded with the use of this technology to make an Oiliness detection in sq1 well area's cretaceous Qing-shuihe oil reservoir.On that basis,several cretaceous favorable goals have been found.
