Abstract：In the study area located in the Athabasca oil sand region of Canada, the target layers are extremely shallow, the surface conditions are complex, and the time of reservoir development is short. Therefore, the difference of seismic data before and after the reservoir development is small, and it is difficult to do 4D seismic consistency processing, extract reliable reservoir change and record secondary logging data. This limits the popularization and application of 4D seismic inversion. This paper proposes a 4D multi-component joint inversion method based on a low-frequency model. The model takes into account the difference of converted seismic data, adds converted seismic data into the inversion process. By using 4D3C seismic data and fully integrating two frontier seismic exploration technologies (“4D” and “multi-component”), the 4D multi-component joint inversion method realizes fine reservoir characterization and dynamic monitoring. The following understandings are obtained: ①Real-time combination of processing and interpretation and step by step quality control improve the consistency of non-reservoirs, and retains and highlights the real difference of reservoirs; ②rock physics analysis shows that the velocity ratio of compressional and shear wave is most sensitive to reservoir change and can be used as a sensitive parameter for dynamic reservoir monitoring; ③by making full use of time-shift information of compressional seismic data and converted seismic data, the low-frequency model reflecting reservoir variation can be established, which avoids the limitation of secondary logging data. The method is simple and easy to use, and the prediction of steam chamber is accurate and reliable.
