At high speed, asphaltene plugging is more serious with increase of flow rate. The damage degree of asphaltene plugging is higher in low permeability core than in high one.
在较高流速下，随速度升高，沥青所造成的孔喉堵塞更加严重，在低渗岩心中沥青堵塞引起渗透率伤害程度大于高渗透岩心。
The space degree and permeability of two groups of rock specimens are both raised with temperature and decreased with pressure.
两组岩样随温度升高空隙度、渗透率都是呈现增大的趋势。
Based on the core and logging data, this paper analyses and evaluates density of seams, opening degree, porosity, permeability and seam spacing in the Tazhong area.
