Abstract: The numerical sedimentary forward simulation of Lower-Middle Ordovician of Shunnan area in Tarim Basin was presented by means of software Dionisos, which are controlled by primary model, tectonic subsidence, fluctuation of sea level, sedimentation rate and wave energy. Through the validation, the appropriate model has been chosen and then the sedimentary process is clear. The evolution of this area has four deposititional cycles. The distribution of carbonate reef, beach and short-time exposed surfaces has been analyzed. During Early-Middle Ordovician, there developed four frequent short-time exposure surfaces which occurred at the top of the depositional cycle in Shunnan area and resulted in the formation of vugular-pore in carbonate deposits subjected to leaching and dissolution of meteoric fresh water,leading to which makes a change that only the fracture dominates the development of the carbonate reservoir.
