查询词典 permeability

The silicone rubber membrane used in SRMBR is a polymer-made non-porous material. It is hydrophobe and non-permeable to inorganic salt, and has the high selective ethanol permeability. Compared to the conditional separation technology, the pervaporation through SRM has the advantages of low-cost and low-pollution, especially applicable to separating volatile matter from organic matter-water system or organic-organic matter system.

The results indicate that the different thermal expansions and elastoplastic properties and distributed randomness of various mineral particles composed of oil shale will lead to the nonuniformity of thermal field, deformation field and stress field in heating process, which makes the particles of oil shale deform incompatibly: and the release of product pyrolysis results in irreversible damages of oil shale material and structure. These are the main reasons for the thermal fracture of oil shale. When oil shale is heated through thermal conduction, temperature transfers slowly, so the spacing between heating well and production well should not be kept too long. When difference exists in oil shale reservoir's properties, heating well should be chosen in the high conductivity region. Oil shale's stratification is vital for developing permeation zone in in-situ retorting. Oil shale will generate additional expansion force as it reaches its pyrolysis temperature, and stratification will be cracked first, so the oil shale stratification should be utilized to enhance its permeability.

研究结果表明：组成油页岩各种矿物颗粒热膨胀和弹塑性性质的不同及其分布的随机性，导致油页岩加热过程中温度场、变形场和应力场的非均匀性，使得油页岩颗粒间变形不协调和油页岩热解产物释放引起油页岩材料与结构性能发生不可逆的劣化损伤，这是油页岩发生热破裂的主要原因；热传导方式加热油页岩，温度的传递比较缓慢，加热井和生产井的间距不宜过大，对油页岩储层性质存在差异时，注热井应选择较高热导率的区段；油页岩的层理对油页岩地下原位开发形成渗透带至关重要，油页岩达到热解温度会产生附加的膨胀力，首先在层理处开裂，应充分利用油页岩层理赋存条件改造其渗透性。
