摘要
本文根据烃类二次运移机理、静水条件下气藏的原始气水分布受控于浮力和岩石的毛细管阻力等,用毛细管压力曲线确定气藏含气饱和度,使之更接近于气藏的原始含气饱和度。该方法的技术关键是建立等饱和度下的毛细管阻力与含气高度的数学关系式。
Based on secondary migration mechanism of hydrocarbon compound and gas reservoir's initial gas-water distribution controlled by capillary resistance of buoyancy and rock in the static water condi- tions, it is described that the gas saturation determined by capillary pressure curve is close to the gas saturation of gas reservoir in this paper. The technical key of this method is to build up the mathemati- cal dependence of capillary resistance and gas bearing height under equal saturation.
