In this paper, we took the time-distance curve equation and the Normal Moveout (NMO) principle as breakthrough point. According to the forward seismic simulation model and the cross-correlation principle in signal processing, we have convincingly studied the accuracy of NMO in simulation experiment. Firstly, the time-distance curve equation of single-layer reflection and the characteristics of cross-correlation are simply analysed. Then, we build the seismic forward model by Tesseral software,

The conclusion shows that the method effectively demonstrates the feasibility of the cross-correlation method in testing the accuracy of NMO, and provides a new idea for analysing the accuracy of velocity picking, even the accuracy of the underground model during petroleum exploration.
