At the super-low permeable reservior sandstone of Fu and Yang in Daqing Oilfield, many pore throats exist a lot in the types of compacted and restored flakes and curved lamellas while the pore volume of micropore and the thin, compacted and shrunken throat that contribute little to flow take large scale in the total pore space. Thereof high filtrational resistance is caused by much trouble including high content of reservoir shale, serious sensibility to pressure at waterflooding, remarkable effects of undersaturation and water blocks in micropore. A method with laboratory experiment, theoretical confirmation and field application included was adopted to analyze the non-linear flow characteristics, to reveal the deep mechanism of pinhole enveloping macropore and to provide a new technology of improving the development effect. The outcomes aquired are as follows: Multiple cores with different low and super-low permeability were selected to perform seepage experiments by gas, water and oil. Three fields of flow were observed in the reservoir at different low and super-low core permeability. They are pseudo- elastic flow, transition flow and plastic creep flow. So the concept that there was no correlation of rocky absolute permeability with fluid properties that pasted itself was broken up. Two-phase seepage of water displacing oil in uniform super-low permeability shows that the two-phase seepage zone is narrow.

针对大庆油田扶、杨特低渗透油层砂岩孔隙喉道的大小和形态以压实再生型片状、弯片状喉道分布较广，压实、缩小型细喉道型，微孔不可流动的孔隙体积所占总孔隙体积的比例较大的特点；及储层泥质含量高，注水开发中压力敏感性强、微孔隙欠饱和及水锁效应显著，导致流体渗流阻力增大的问题，本文采用室内实验、理论推证和矿场应用相结合的方法，研究、分析了流体非线性渗流特征，更深刻地揭示出小孔包围大孔的机理及产生原因，并提供了改善开发效果的新的技术方法，取得如下成果：选择不同渗透率的低渗透、特低渗透岩心，进行了气、水和油单相渗流实验，揭示出当岩心渗透率不同时，油层内的流体呈现出拟弹性流变、过渡流变、塑性蠕变三种流变区，从而打破了岩心的绝对渗透率与通过岩心流体性质无关的观点；同类特低渗透岩心的水驱油两相渗流实验表明，两相渗流区较窄。

Look in him, because mode of industry net alliance gathered together,industrial catenary swims up and down numerous link, can offer for traditional business include a domain name to register, build station, information to push send, attestation of online and network sale, interactive, aptitude, trade match those who wait inside is one-stop electronic business affairs serves, and the partner of industry net alliance also can be used in the ascendant be based on " 1P " academic tripartite pays cost mode, acquire the reasonable interest such as redound of sale of sale promotion, product, investment, accordingly, mode of industry net sale is expected to become afterwards in future after the member makes sale pattern another mainstream mode.

在他看来，由于行业网联盟模式汇聚了产业链上下游众多的环节，并可为传统企业提供包括域名注册、建站、信息推送、网络营销、在线互动、资质认证、交易匹配等在内的一站式电子商务服务，而行业网联盟的合作伙伴亦可利用方兴未艾的基于&1P&理论的第三方付费模式，获得营销推广、产品销售、投资回报等合理利益，因此，行业网营销模式在未来可望成为继会员制营销模式之后另一个主流模式。

The nonlinear mechanical model of contact between soil particles was established based on the effects of liquid bridges on mechanical microstructure of soil and the basic Distinct Element Method theory. The dynamic behaviors of dry soil ahead of the bulldozing plate with different cutting angles were simulated by DEM.

The mathematical model by which the forming time can be precisely calculated is ratiocinated. This model shows that in SLS the scanning "delay" phenomenon can make the actual forming time greatly exceed the theoretical time, and the total number, total length of the scanning lines and the scanning speed have different effects on the scanning "delay".

This thesis collects 21 refurnishing work samples, using SPSS program and by means of regression analysis to estimate the generation coefficient for refurnishing waste, it's 0.139t/m2 or 0.231m3/m2 (assume the density of waste is 0.6t/m3), based on the building area. We can also use the coefficient mentioned above to calculate the theory quantity for refurnishing works.
