Scanning electron microscopy,transmission electron microscopy,circular dichroism and small-angle X-ray diffraction were used to analyze the aggregation mode of CSG in the organogel phase.A hierarchical self-assembly model was proposed to explain the transition from molecular to primary and secondary structure.It is shown from our results that CSG can aggregate into a micellar fibril nanostructure with high length-to-width ratio which is bundled and entangled to form a three-dimensional(3D) network that immobilize the fluid component probably by surface tension.Moreover,sol-gel polymerization of tetraethoxysilane was carried out using CSG in the gel phase.

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.
