不平衡效应对稠油渗流的影响

本文利用稠油的多组分模型，研究了不平衡效应对粘弹性稠油在多孔介质中渗流的影响。通过建交我孔介质中存在不平衡效应的一维有界不稳定直线渗流的数学模型，分别推出了渗流初期和后期的压力分布解析式，并与一般牛顿流体渗流进行了比较。结果表明，不平衡效应使得渗流过程中的压力下降缓慢，在实际的稠油开采中，要合理的利用稠油的粘弹特性。

Non-Equilibrium Effects on Heavy Oil Flow in Porous Media

This paper studies the non-equilibrium effects on visco-elastic heavy oil flow in porous media with a heavy oil multi-component model. Analytical formulas of the flowing pressure distrbution during the initial and later stage are derived respectively by establishing the mathematical model of one dimensional unsteady bounded linear-flow which takes account of non-equilibrium effects and compared with the results from classical Newtoni-an fluid flow in porous media. The result shows that non-equilibrium makes the flowing pressure decrease slow-ly. In the practice of heavy oil development, the visco-elastic characteristics of heavy oil should be reasonably uti-lized.
