摘　　要：牙哈23凝析气田是国内第一个采用整体循环注气部分保压开发的凝析气田,进行有效水体及驱动能量的估算对充分利用天然能量、保持合理的回注比、实现气田开发效益的最大化意义重大。通过物质平衡法,求得牙哈23凝析气田凝析气地质储量及有效水体大小,建立了计算牙哈23凝析气田水侵量数学模型,同时计算了开采期间各驱动指数的变化情况,为该气田的动态认识及下步生产调整提供了可靠依据。The whole cyclic gas injection and partial pressure maintenance processes are used for development of Yaha23 gas condensate reservoir firstly in China.In order to take full advantage of the natural energy maintain the reasonable recirculation ratio and maximize the economic benefits,it is very important to estimate the efficient aquifer size and drive energy.In this paper with material balance equation,the mathematic model is set up to calculate the gas in place and the efficient aquifer size of Yaha23 gas condensate reservoir.The change of drive index during production is also calculated the result provides significant guidance for the dynamic analysis and following-up production of Yaha23 gas condensate reservoir.
