| 摘 要： | 针对稠油松散岩心的相对渗透率曲线计算问题，根据渗流力学及最优化理论，给出了描述岩心内部油、水两相渗流的简化方程，并利用约束变尺度法求解最优化问题，基本解决了岩心堵塞以及结果对初值的敏感性问题。通过实例计算，说明了本方法的可靠性和可行性。

| Abstract: | Aiming at obtaining the relative permeability curves of unconsolidated Corecontaining heavy petroleum,a set of governing equations are obtalned based on porousmedium flow theory and optimum theory. The optimum problems are solved by means of constraint Variable metric method.The sensitivity and blockage of results to initial data iseliminated.Several examples are included to illustrate the reliability and usefulness of this method. |
