     In Lunnan lower uplift, low amplitude trap was densely developed, and more than 90% of these traps have amplitude less than 10 meters, and that has out of the ranges in seismic resolution with current technique. Therefore, the challenge of reservoir rolling evaluation in this area is how to locate these low amplitude traps. Considering the inheri- tance of the Triassic structure in this area, the amplitude of these traps was calculated with two methods： sedimentary de- position＇ s palaeo-thickness bed by bed recuperation and sedimentary basin clasolite＇ s originality thickness experiential recuperation, referred to the height of the karstic residual buried-hill in Ordovician. The result was proved by drilled wells and depicted that these two methods were both effective.
