AN OPTIMUMARITHMETIC FOR RELATIVE PERMEABILITY OF UNCONSOLIDATED CORE CONTAINING HEAVY PETROLEUM

  • 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.
