The results suggest that the uranium content and 234U/238U ratio s in the sandstone of the redox transition zone are generally higher than those of the oxidation and reduction zones,while the Th/U ratios of the transition zon e are lower than those in sandstone of the oxidation zone and the reduction zone .234U/238U and 230Th/238U ratios in uran ium ore samples are in the range of their ratios in the redox transition zone.

研究表明，与氧化带、还原带相比，氧化-还原过渡带具有较高U含量和234U/238U比值，较低Th/U比值；矿石样品中的234U/238U、230Th/ 238U比值位于过渡带范围内，234U/238U比值偏高区往往是过渡带分布区。

Fluid pattern is suitable for NMR porosity calibration in Berea sandstone as well as terrestrial sediment sand with little shale content and well sorted. Ceramics reference material is applied to shaly sand with average sorted. Both fluid pattern and solid ceramics material are not suitable for calibration in sandstone sample with high clay content, complex lithology with rich paramagnetic materials.

流体标样适合于贝瑞砂岩、陆相沉积分选好、泥质含量低的砂岩NMR孔隙度的标定；固体陶瓷标样适合于分选中等的泥质砂岩NMR孔隙度的标定；对粘土含量高的砂岩、含顺磁性物质的砂岩和砾岩等复杂岩性岩样，用流体标样和固体陶瓷标样标定都得不到准确的NMR孔隙度值。

Two dominate variation trends are distinguished in the data plots of compressional-wave velocity versus Possion ratio, indicating the effects of mud content and calcite cement on the elastic properties of sandstone samples. In each change trend, with the rock texture transfering gradually from grain-supporting to matrix-supporting with increasing mud and calcite cement content, the propagation of elastic wave also changed from grain-to-grain contacts to rock matrix, which resulted in the measured data illustrating extremely different tendency. It helps utilize the physics properties of reservoir sandstone to extract rock texture and diagenesis properties in the research area.

样品在纵波速度－泊松比交汇图中表现出两种主要变化趋势，分别对应泥质与钙质胶结物的影响；在每个变化趋势中随泥质含量与钙质胶结物含量的增加，岩石结构从颗粒所构成的骨架支撑逐渐表现为基质支撑，弹性波能量的传播也从通过颗粒接触边界转变为通过岩石基质传播，这是使砂岩样品测试结果表现出两种截然不同变化趋势的主要原因，为利用岩石物理特性从地震资料中提取岩石结构、沉积与成岩特征的信息提供了依据。
