摘要: 将干气在高压条件下注入高凝析油含量的凝析气藏,能够减缓地层压力下降速度,有效抑制反凝析,提高凝析油的最终采收率,这是高效开发高含油凝析气藏的最好方法。利用气驱特征曲线方法来研究凝析气藏的开采动态,通过牙哈23凝析气藏的生产动态数据验证了气驱特征曲线规律的可靠性,建立了累计产凝析油量与生产气油比的关系。依据此关系式,在凝析气藏达到废弃条件时,即可用该方法确定其凝析油的可采储量。

Abstract: Injecting dry gas into condensate gas reservoir with high oil content under high pressure can slow down the decline rate of formation pressure, restrain retrograde and improve ultimate recovery of condensate oil. As the best method to develop condensate gas reservoir with high oil content, this paper proposes a method for using gas?drive characteristic curve to study the production performance of condensate gas reservoir. The case studied results are used to verify the reliability of such a gas?drive characteristic curve pattern by the production performance data from Yaha?23 condensate gas reservoir, and develop the relationship between cumulative condensate oil and produced gas?oil ratio. When the abandonment pressure is reached in condensate gas reservoirs, this method can be effectively applied to determine the recoverable reserves of condensate oil
