实验结果表明，裂缝的存在对低渗透储层的渗流特征有明显的改造，裂缝开启前，储层渗流可以看作是基质岩石渗流，裂缝对渗流的影响不大；裂缝开启后，由于其渗流能力较强，将发挥主要的渗流通道作用。

The loading process of trehalose has no effect on apoptosis of platelets. The efficacy of trehalose plus phosphate in suppressing apoptosis of platelets during cryopreservation is superior to that of only trehalose. Compared to 6% DMSO and 2% DMSO plus TS, trehalose plus phosphate can retain the same platelet count, superior hypotonic shock response and platelet aggregatory reaction to ADP, and lower apoptosis rate of platelets. Platelets cryopreserved with trehalose plus phosphate can retain intact ultrastructure.

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.
