, China; 4. Xi’an University of Science and Technology, College of Safety Science and Engineering, Xi’an 710054, China) Abstract: The circular thin plate specimens of different porosity were made by the method of controlling sand sizes. RSM-SY7 automatic ultrasonic measuring instrument with foundation piles and more cross-holes was used to measure and mark the values of porosity. Permeability test......

with a series of experiments including casting thin slice, SEM, the techniques of physical properties and so on. And a simulation equation corresponding to porosity was established according to the feature of diagenetic evolution and the generalized geologic effect. By comparing the route of porosity evolution of Chang 6 sandstone reservoir in Jiyuan Oilfield and Huaqing Oilfield, the difference......

geometry, porosity, microstructure and mechanical properties of the stitch welded seams were investigated by digital microscope, optical microscope, scanning electron microscope and universal tensile... nozzle. Porosity formation could be suppressed with the gap between plate and skeleton less than 0.1 mm, while the existing porosity can be reduced with remelting. The maximum shear strength of stitch......
porosity 5.1%. With the addition of 5%(mass fraction) CNTs, the density of the composite block is elevated to 1.84 g/cm3, and its open porosity is reduced to 3.5%. The flexural strength of composite block...; flexural strength; density; open porosity ......
