The invention relates to a process for preparing a large super-thick nodular cast iron container sample, which comprises: taking out a TM sample by using a trepanning drill blind hole sample preparation process, removing excess materials by turning or milling, and sequentially preparing a casting body by using the following processes: preparing a TD sample by using a trepanning drill; drilling a circle of central row holes at the diameter distribution position of the TD sample, wherein every two central row holes are intersected; longitudinally drilling three rows of through holes in the positions of the side face row holes and are evenly distributed in the circumferential direction by 120 degrees, and evenly dividing the positions of three sets of H1000 samples of the nodular cast iron container shell into three fan-shaped parts; sawing the 120-degree fan-shaped part into a 90-degree part and a 30-degree part respectively; longitudinally sowing off the 90-degree part in a five-equal-part mode according to 17
