Characteristics of water absorption capacity of weathered sandstone based on nuclear magnetic resonance and wave velocity testing [PDF]
Water is a key factor in the weathering and erosion of rocks, and highly porous rocks are generally more susceptible to weathering. However, there has been a lack of in-situ methods for assessing the water absorption capacity of rocks. To investigate the

Shuitu Baochi Xuebao, 2018 利用改进的ZC-2015型渗气仪对不同类型的原状风干和重塑的马兰黄土进行渗气试验，分析土样体积、渗径、干密度、取样深度等对渗气率ka的影响，并利用扫描电镜（SEM）试验得到的孔隙结构参数解释黄土渗气特性。结果表明：渗气率ka不仅是气体渗透特性的衡量指标，也是描述非饱和马兰黄土孔隙和结构特征的重要参数。不同体积的土样由于尺寸效应，其渗气率随着土样体积的增大而增大。另外，渗气率随着渗径、干密度的增大而减小。对比3种不同类型黄土的透气性试验结果和电镜照片，并结合统计的孔隙结构参数 ...

Logging Response Characteristics of Gas Hydrate Formation in Shenhu Area of the South China Sea [PDF]
, 2010 分析了南海北部神狐海域含天然气水合物沉积层声波速度及密度的分布特征和变化规律,并通过对比dSdP 84航次570号钻孔含天然气水合物层段测井资料,总结出神狐海域含水合物地层的测井响应规律特征:神狐海域含水合物地层存在着明显的高声波速度、低密度特征,地层密度随声波速度的变化并不是单一的反比例关系,总体趋势上随声波速度的升高而降低;含水合物地层高声波速度值主要集中在197--220 M段,饱和度值在15%--47%之间,低密度值集中在200--212 M段,分布在水合物饱和度大于20%的地层内 ...

Shuitu Baochi Xuebao目的为探究间歇性降雨条件对黑土表层孔隙结构和团聚体周转的影响。方法以黑土表层土壤为研究对象，采用稀土元素示踪法+人工模拟降雨+CT扫描相结合的研究方法，阐明表层团聚体特征、表层团聚体的周转特征、表层土壤孔隙特征对降雨强度和降雨次数的响应。结果间歇性降雨条件下，孤立孔隙均集中于土壤表层。随着降雨次数的增加，雨强40 mm/h下连通孔隙度始终大于孤立孔隙度，雨强70 mm/h下连通孔隙度和孤立孔隙度交替出现最大值。对于大团聚体，随着降雨次数的增加，当连通孔隙度减小时，5~2 mm团聚体破碎成0.25~0 ...
