摘要

通过对纵波速度变化趋势的分析,探讨了如何利用叠后地震资料的反演成果进行砂体解释,并首次提出了"门槛值体"法。结果表明,该方法对于解决由沉积作用引起的阻抗平面变化所造成的砂体解释的不确定性有很好的效果。
Based on the analysis of the P-velocity variation trend of the reservoir, the paper discussed how to use the data inverted from post-stack seismic data to interpret a sand body, and proposed the method of "threshold value volume" for the first time. The result showed that the method have a great effect in solving the uncertainty in the sand interpretation caused by the deposition.
