| 摘 要： | 废弃产量和废弃压力是标定凝析气藏可采储量的重要参数。在一年一度可采储量标定工作中发现,目前所提及的废弃条件的确定方法对于带水凝析气藏而言或说法不确切,或计算方法不适应,或精度不高。根据多年可采储量标定的经验,针对东海带水凝析气藏实际情况,提出一套适应于东海地区带水凝析气藏废弃产量和废弃压力的确定方法,且以东海XX气藏YY井为例,结合油藏工程、采油工艺等专业,介绍计算方法具体运用,对于具有同样地质特征气藏具有一定的借鉴意义。

| Abstract: | Abandonment gas production rate and abandonment pressure are the key parameters of calibrating condensate gas reservoir recovery ratio. But at the process of calibrating recoverable reserves, it＇s found that the way of defining the abandonment conditions is not exact or theoretical equation that calculating the abandonment pressure is not applicable or the accurateness of empiric equation is not good. According to experience of calibrating recoverable reserves for many years, a method for defining the abandonment gas production rate and abandonment pressure of ponded condensate gas reservoir was proposed. Taking the well YY of XX gas reservoir in the East China Sea as an example and using petroleum reservoir engineering and gas production engineering, a new calculating method was introduced which will provide reference for calculating recoverable reserves of gas reservoir with the same geologic characteristics. |
