摘　　要：胜利油区目前投入开发的气藏大多数属于构造背景上的岩性气藏,受断层及岩性的控制,水体是封闭的,其大小是有限的。在开发过程中,其动态特征表现为产水量小、生产水气比低。将气藏这一具体地质开发特征与物质平衡理论相结合,给出了水体能量的动态评价方法。实际运用表明,该方法的计算结果是可靠的,具有很强的实用性。The gas pools exploited in Shengli oilfield mainly belong to lithologic traps controlled by fractures and lithology, with closed and size-restricted water. Their performances in process of development are characterized by low water production and low water/gas ratio. This paper presents the dynamic evaluation method for calculation of water energy, based on the performances and material balance theory. The case study indicates that the calculated result by this method is reliable and practicable.
