【摘要】 地震频谱衰减属性可反映地层吸收性质、岩相和含气性,利用含气层段对地震波高频能量吸收强特点,可较好地预测地层含气层段[1].利用此项技术对车排子周缘的Sq1井区三维白垩系清水河组油藏进行含油气性检测,扩大该地区白垩系油气勘探领域.在此基础上,已发现多个白垩系有利目标.更多还原

【Abstract】 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.更多还原
