Several straight lines will appear at semi-log curve for transient pressure of the wells in multi-media reservoirs.
在多重介质油藏非稳态压力的半对数曲线上,往往会出现多条"直线段",但是由于其中各种介质的渗透性不同,使得曲线间存在各种差异,理论推导和曲线特征研究证明,在只有一种介质可以渗流的多重介质油藏的非稳态压力的半对数曲线上,才会出现多条相互平行的直线段,而在多种介质同时具有渗透性时,实际上只有最后的系统径向流段才能在半对数曲线上出现直线段,而其他部分则都是曲线。
Odd-even steps interpolation algorithm for logarithmic curve in multi-axis control;
对数曲线的多轴联动奇偶步插补算法设计
The research results show that the triaxial frost heaving stress-strain curve can be fitted with a logarithmic curve,and test-force-ring stiffnes,initial axial pressure and confining pressure have a great effect on the frost heaving stress and strain of frozen saturated clay.
结果表明:三轴冻胀应力-应变关系呈对数曲线变化;测力环刚度、初始轴向压力及围压对冻胀应力和冻胀应变有显著影响。
