摘　　要：天然气动态储量的计算方法很多,其中物质平衡法是广泛用于计算气藏(气井)单井动态储量最常用的方法,而压力恢复法也是计算气井动态储量的常用试井分析方法,它们有很多优点,其应用程度已被矿场实际证实,但它们都有各自限制的应用条件,很难说明哪种方法计算更可靠,特别是压力恢复法分析气井单井动态储量。将上述两种方法的结合建立多目标优化函数,使其计算储量趋于一致。该方法既能很好地应用压力恢复法,又能体现压物质平衡法,克服了各自的应用缺点,使得该方法适用范围更广,计算结果更可靠,特别对致密气藏具有更好的推广应用价值。通过实例气井动态储量进行的验证对比,说明该方法在理论上是合理的,通过实际验证是可行的。The material balance method is the common one in those of calculation the dynamic reserves of gas reservoir. Pressure buildup method is a conventional well test method of calculation the dynamic reserves of gas well. Those two methods have many strong points and those strong points have been verified in a certain extent by the practical application in the field. But it is hard to ensure which one is more suitable for the limiting condition of their own, especially the pressure buildup method for the analysis of dy- namic reserves of gas well. One method united by the two methods enable the reserves calculation coincides with each other by establish a multi--objective optimization function. This method has many advantages, for example, more excellent apply of the pressure buildup method also incarnate the material bal- ance method,overcome the shortcoming of their own,make the applicability of the method more roominess and the result more confidence, more popularize and apply value especially for the tight gas reservoir. Through the comparing and verifying of the field example of the dynamic reserves of gas well indicate that the method is reasonable in theory and viable in the field validate.
