透水层，透水岩层
1、fossiliferous strata───化石地层
2、strata───n.层；[地质]地层；阶层；n.(Strata)人名；(意、塞)斯特拉塔
3、freehold strata───不动产地层
4、leaflike strata crossword───叶状地层纵横字谜
1、capacity of the intermediate and low permeable strata increasing and the water intake capacity of the high permeable strata reducing are marked by the permeability grade increasing.───渗透率级差越大，低渗透层相对吸水量提高，高渗透层相对吸水量降低幅度越大，调剖效果越显著。
2、permeable condition of shale reservoirs with stress releasing has been improved, and the current stress field controls the stress distribution of strata.───应力释放区的泥岩储层渗透条件得到改善，现今应力场控制着地层压力的分布。
3、major pay bed is low permeable ultra dense sandstone. Its permeability and pore throat texture are very sensitive to the net pressure of overlying strata.───主要产层为低渗透超致密砂岩，其渗透率和孔喉结构对上覆地层净压力很敏感。
4、The porous permeable strata are called carrier beds. They are the pathways for hydrocarbon migration.───渗透性地层称为输导层，它是油气运移的通道。
