چکیده

Relative permeability is an important parameter in modeling, simulation and evaluation of gas injection. In this study, new empirical-mathematical models are developed to predict relative permeability of and water/oil systems in different rock and fluid systems. The Multi-Gene Genetic Programming (MGGP) technique is employed to develop relative permeability equations. The smart correlations presented in this work require capillary number, interfacial tension, API, gas molecular weight and viscosity ratio as extra input variables to improve its precision and accuracy. The new models are evaluated by experimental data extracted from literature and validated by extensive error analysis. The results strongly admit the MGGP approach and high accuracy of developed mathematical correlations.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
