The calculation method for multi-stage rift subsidence process and deep thermal evolution in the present invention can describe the multi-stage rift subsidence process of a basin more accurately, is of great significance for correctly understanding and quantitatively evaluating the dynamic process of a multi-stage rift basin, and can predict various basin processes including deep heat flow.
