| 摘 要： | 将地震高分辨率非线性反演方法应用于地震频带窄、主频低和信噪低的鄂北区块地震剖面的反演,获得了品质高和分辨率高的地震反演剖面.应用这种高分辨率反演剖面对鄂北区块的薄互层进行了有效而可靠的划分和精细追踪,并展示出砂体的分布和厚度变化特征.在这种高分辨率反演剖面上可拾取最小厚度为4.0 m的砂体,其最小误差为2.3%.在鄂北区块的应用表明,该方法可用于识别薄互储层.

| Abstract: | High resolution non - linear seismic inversion is used in Ebei Block, where has narrow seismic frequency band, low predominant frequency and low signal - to - noise ratio, and high quality and high resolution seismic inversion profile had been obtained. The thin interbeds in the block are effectively divided and traced with this profile, and the distribution of sands and the change of sand thickness are shown. This high - resolution inversion profile can pick a minimum sand thickness of 4.0 meters, with minimum error of 2.3 %. The application in Ebei Block shows that high resolution non- linear seismic inversion and its profile have especial efficacy and function in precise research of thin and interbedded reservoir. |
