文章利用气藏工程与数值模拟的方法,定量分析了地层系数Kh、产水、非达西流系数D、地层压力及表皮系数等因素对不同储层条件下气井绝对无阻流量的影响程度,并得出防止储层污染、对储层进行有效改造、合理利用地层能量是获得气井高产稳产的重要保障的结论。

This paper quantitatively analyzes the effect of formation coefficient, producing water, non-Darcy flow factor D, formation pressure and skin factor on absolute open-flow capacity of gas well under different reservoir conditions. It comes to a conclusion that protecting formation against pollution, improving formation and reasonably utilizing formation energy are important for gas well to get high and steady production.
