| 摘 要： | 考虑气体在地层水中的溶解度、矿化度和表面张力引起的气泡内外压差等因素对气体泡沫体积性质的影响,推导出气体泡沫的理论状态方程,并结合分析对该模型进行了化简,对泡沫的气相和液相分别选择了合适的密度模型。计算结果表明,泡沫理论状态方程具有较好的计算精度和满意的预测能力,能够用于理论分析和现场应用。

| Abstract: | A theoretical model of state equations of gas foam is derived and simplified by considering the impacts of gas solubility,formation water salinity and surface tension on foam volume.Suitable density models are selected respectively for gas phase and liquid phase.Calculation results indicate that the theoretical state equations of gas foam can be applied to theoretical analysis and field practice with high calculation accuracy and satisfactory prediction capability. |
