【摘要】 地震反射层的地质层位是地震资料解释的基础,确定地震反射层的常用方法是利用声波测井资料,通过合成记录与反射层的标定。但声波测井的分辨率较高,地震记录的分辨率低,直接利用声波测井曲线制作合成记录,与实际地震记录进行层位标定常常不匹配。为提高层位标定的准确性,参考了多种测井曲线与岩性的对应关系,以及合成记录极性与岩性和层位的对应关系,在辽河盆地东部浅海地区实现了准确的层位划分。更多还原

【Abstract】 Seismic horizon labeling is the basis of structural interpretation of seismic data. The usual method of seismic horizons labeing is to tie the seismic synthetic record made by sonic curve to the reflection horizons. The reflection horizons of seismic record usually does not, however, match the seismic synthetic record well, because of the low resolution of seismic record and the high resolution of sonic curve. To improve the veracity of the seismic horizons labeling, by analyzing the relationship between the multiple well logging data and the lithology, and the connection between the polarity of seismic records and the horizons of lithology, we realize reasonable seismic horizons labeling in the east shallow sea area of the Liaohe basin.更多还原
