Physical simulation, numerical simulation and field test are the three primary methods of EOR research,. 3D large-scale simulation device has a very important role in understanding the mechanism of SAGD development, but due to the long cycle of the experiment, the more investment in human and material, it not be able to carry out much more experiments , Using the digital experimental techniques, tracking production data and temperature field of SAGD experiment, and then, reappearing SAGD physical simulation process，expanding SAGD physical simulation program, rich SAGD physical simulation results.
