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.

The proposed robust road main direction detection method consists of initial main direction extraction based on the direction histogram of structure tensor and precise direction detection on vectorized edge image. Experiment results demonstrate its robustness and precise. The proposed Gibbs-sampling-based method models road network with marked point process and can effectively extract road network with initial configuration. However it is slow and still can not deal with single and isolated road segment. These problems can be solved by the real-time method. And experiments verify that the real-time method is fast during extracting road segment.
