疏松砂岩稠油油藏孔隙度大，胶结疏松，粘土矿物含量偏高。
Heavy oil reservoir of loose sand is of large porosity, loose cementation and higher clay content.
软土在我国广泛分布，软粘土的显著特性是含水量高、孔隙比大，抗剪强度及渗透系数低和压缩性、灵敏度高。
The other quality of the soft clay includes smaller shearing strength intensity and higher coefficient of compressibility and so on.
淤泥，粘土和土坯往往是固体流，而不是障碍，吸收水，因此考虑在沙子，覆盖或其他材料，以增强吸收低孔隙度地面。
Silt, clay and adobe often form solid barriers that shed water instead of absorbing, so consider adding sand, mulch or other absorption enhancing materials to low-porosity ground.
