The quantitative evaluation of the Upper Cretaceous oil shale has been conducted by abundant testing, log and seismic data from the Songliao Basin in Northeast China. Based on the log-seismic characteristics of oil shale, the technique of log-seismic multi-attributes reconstruction to evaluate single-well oil shale has been adopted. By using the method of log-con­strained seismic inversion, the inversion volume of wave impedance, total organic carbon (TOC), and oil yield have been obtained to carry out evalua­tion of oil shale. According to the evaluation results, the inversion of wave impedance can only be used for qualitative evaluation of the spatial distribu­tion of oil shale. Meanwhile, the inversion of TOC and oil yield can be used not only to evaluate the spatial distribution of oil shale, but also for quantitative evaluation of the quality of oil shale. Hence, the evaluation technique of oil shale was developed combining single-well log evaluation and spatial seismic evaluation, which integrates the quantitative evaluation of oil shale with geophysical technique.
