Under best centrifugal force, author selected a lot of representative Glutenite、carbonatite and vulcanite cores and carried on centrifugal experiments and NMR T_2 measurement, and determined T_2 cutoff value of each cores, This *** also selected a certain amount of representative fresh oil-bearing sandstone for calibrating T_2 cutoff value, and analyzed influence of T_2 cutoff value with original wettability of core.

在最佳离心力下，本文选取了大量有代表性的砂砾岩、碳酸岩和火山岩岩心进行了离心实验和核磁共振T_2丈量，确定出了对应岩心T_2截止值大小，本文还选取了一定数目有代表性的新鲜含油砂岩湿样进行了T_2截止值标定，分析了岩心原始润湿性对T_2截止值的影响。

The gravels, plants and water contain gold, which can contribute to the regeneration of gold placers in permafrost region.

Cold places like cold stone substrate, transparency, quality nourish, low hardness, gloss strong line better varieties; soft ground nearly frozen to substrate, but the lack of transparency; just manner, then the hardness high, often with quartz quality of sand screw; hard the worst quality, hardness, opacity, gloss weak, often more impurities, and rock in the gravel. 3, defects, including impurities and cracks in the stone.

冻地的底质似冻石、透明度高、质细润、硬度低、光泽强，系较佳品种；软地的底质接近冻地，但透明度不足；刚地，则硬度偏高，常含石英质砂钉；硬地的品质最差、硬度大、不透明、光泽弱，常有较多杂质和围岩中的砂砾。3、瑕疵，包括石中的杂质和裂纹。
