With the continuous improvement of conventional oil and gas exploration，the eastern old oilfields，especially Shengli Oilfield，are facing a new situation and new task of expanding exploration field and opening up situation of unconventional oil and gas exploration. Compared with North American marine shale oil，continental shale oil has its own particularity of complex reservoir-forming conditions and being lack of corresponding quantitative evaluation technology. Therefore，taking the Lower Es3 Member of Luojia area in Jiyang Depression as an example，on the basis of definition of the logging response characteristics of shale oil“sweet spot”，the logging quantitative identification model of shale oil“sweet spot”in Luojia area was established，by which the logging quantitative identification of shale oil“sweet spot”is realized.Meanwhile，the relationship between key geological and engineering factors，including TOC，lithofacies，fracture and brittleness，and pre-stack and post-stack seismic information was discussed. Four categories of unique seismic prediction technologies were generated，including the inversion prediction of TOC under multi-logging curves constraint，the sedimentary parameter based shale lithofacies prediction，post stack seismic data based gentle angle fracture density quantitative characterization，pre-stack elastic parameters based shale brittleness characterization. Finally，based on the seismic prediction results of four key geological and engineering factors and constrained by logging quantitative identification，a“sweet spot” seismic characterization model is constructed，which realizes quantitative evaluation of“sweet spot”in continental shale oil with the well-seismic joint technology，and achieves good application results.
