不渗透性

The binomial deliverability equation can only be used to describe the high velocity non-Darcy filtering flow. For low permeability fracturing gas wells, due to low permeable property and high flow conductivity of the formation, the filtering flow laws of the formation are different from those before fracturing, and binomial deliverability equation can not be used for the flow condition of gas wells, therefore, new equation is needed.

二项式产能方程只能描述高速非达西渗流，对于低渗压裂气井，地层的低渗透性和裂缝的高导流能力使得其渗流规律已经和压裂前大不一样，二项式产能方程已无法描述气井的生产状况，必须建立新的方程。

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 .

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。

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.

Unfortunately there exists no official requirements limit for the down and feather proofness.

Almost all CF was released from Dansyl-PE by CTX-IX that osmosed the Dansyl-PE liposome like detergent; CF releases from PE or PS liposome induced by CTX-IX were related with both of CTX-IX and phospholipid concentrations, this indicated that the phase seperation should be a reasonable mechanism for CF permeability of PS or PE liposome in the presence of CTX-IX rather than CTX-IX channel formation on the membrane. CTX-IX influence of CF release of PC liposome was very slight. CF release from Dansyl-PE、PE or PE liposome in response to CTX-IX could be inhibited by Ca〓.

CTX-IX对靶脂如此种种强烈的作用，使得它引起含Dansyl-PE脂质体CF的泄漏犹如击污剂那样强烈；引起含PS或PE脂质体CF渗透的增加为一个与CTX-IX及磷脂浓度有关的二级反应过程，这种动力学特征提示渗透性增加的机制可能是CTX-IX在脂膜上产生的脂质分子相分离，而不是CTX-IX脂膜上形成通道；CTX-IX对PC脂质体渗透性几乎没有影响，而对上述脂质体渗透性增加作用均可被Ca〓所抑制。
