Subject: rock fabric facies Коллеги, прошу совета и консультации!Что такое rock fabric facies? Вот контекст: The extreme petrophysical heterogeneity found in carbonate reservoirs is clearly demonstrated by the wide variability observed in porosity-permeability crossplots of core-analysis data. Research has shown that basic rock fabrics dominate control of petrophysical heterogeneity; within a rock-fabric facies, porosity and permeability have little spatial correlation and are widely variable at the scale of inches and feet... Only rock fabrics, not pore-throat size, permeability/porosity ratio, or flow-zone indicators, have vertical and lateral continuity. Therefore, rock-fabric facies are the basic elements for characterizing a carbonate reservoirs. Если я правильно понимаю, rock fabric - это структурно-текстурные особенности породы, определяющие ее фильтрационно-емкостные свойства. Да или нет? Заранее спасибо за все идеи! |
