摘要
The authors developed a 3-D numerical injection model on parallel TOUGH2-FLAC3 D based on the site-specific stratigraphic information in Ordos Basin to simulate the Shenhua COgeological storage( CGS)demonstration project injection process for three years and forecast COmigration and layers displacement after injection for seven years. The results suggested that COmigration did not stop after three years of consecutive injection,but migration rate was slowing down with time. As a result,displacement near injection well increased with injection and decreased slowly after injection. The maximum displacement of surface center occurred near the end of injection,which was only 1. 24 cm. According to the displacement result,it is safe to continue injecting for this project.
