| 摘 要： | 根据地震层序的时间—层速度数据对研究区建立“纯砂岩”和“纯泥岩”压实曲线方程，然后以时间一平均方程计算研究层的理论砂岩百分比，最后用钻井资料统计的砂岩百分比时计算的理论砂岩百分比予以校正，因而得到能够反映实际情况的校后砂岩百分比。这种定童方法，在T盆地H组实际应用，效果良好。

| Abstract: | According to time-interval velocity data of seismic sequence, we give out the compaction curve equation for "pure sand" and "pure shale" in the area of study, compute theoretical sandstone percentage of objective layers by using time—average equation, and then correct theoretical sandstone percentage in terms of statistcal sandstone percentage. Therefore, we obain the corrected sandstone percentage reflecting practical one. This method proved to be good in H group of T basin. |
