摘要
由于直接利用地震资料难以有效刻画准噶尔盆地征1井区侏罗系三工河组1号、2号含油砂体的分布,这里结合研究工区地质、地震资料特点,采用子波反褶积进行高分辨处理后,利用层段解释技术对目标层段的多种属性进行优选,认为40Hz的分频切片对1号、2号砂体反应最为灵敏。应用40Hz的分频切片刻画的1号、2号砂体分布特征与现有钻井一致,能够有效刻画征1井区含油砂体储层的横向展布。
It was difficult to effectively describe Zheng 1well area of Jurassic Sangonghe No.1and No.2oil-bearing sand body with the direct using of seismic data.To solve the above problem,we combined geology and seismic data characteristics in the research area,optimized the multi-attributes of target stratum by section interpretation technique for wavelet deconvolution of high-resolution processing seismic data.The studied results show the frequency decomposition（40Hz）was the most sensitive of No.1and No.2sand body.Then frequency decomposition（40Hz）was applied to depict the sand distribution of No.1and No.2,being consistent with the sand of the existing drilling wells.It shows that frequency decomposition can effectively characterize the horizontal distribution of Zheng 1well area of oil sand body reservoir.
