【摘要】 地震波的传播速度与地层的岩性、孔隙度、埋藏深度等因素密切相关。速度谱是地震资料处理过程中产生的重要资料,将其与钻井资料相结合,可以用来预测地层的岩性及含油气性。对速度谱资料进行精细解释,提取出层速度,并结合已解释好的层位数据,利用C++编程,可以实现砂泥岩质量分数的自动预测。实际应用结果表明,此方法预测的砂泥岩质量分数结果与钻井资料一致。更多还原

【Abstract】 The propagation velocity of seismic wave is closely related to the lithology,porosity,buried depth of reservoir. The velocity spectrum is the important information created during the seismic data processing. It can be used to predict the stratigraphic lithology and hydrocarbon situation combined with the drilling data. The horizon velocity is extracted through a fine explanation of velocity spectrum data. And the automatic prediction of sandstone and mudstone content can be carried out by C++ programming combined with the interpreted horizon data. The practical application results show that the content of sandstone and mudstone predicated by this method is consistent with the drilling data.更多还原
