摘要： 有水凝析气藏衰竭式开采凝析油采收率受到多种因素的影响,预测难度大。结合平湖油气田平湖组气藏的生产实际,提出了经验公式法、物质平衡法、动态递减法和数值模拟联解法等 4 种方法,预测计算了该气藏衰竭式开采凝析油可采储量。预测结果表明,4 种方法都具有较强的适用性。实际应用过程中可以结合实际情况选择使用,也可以进行多方法的综合评价。

Abstract: Recovery factor of condensate oil in condensate gas reservoir with water developed by natural depletion is affected by many factors and hard to forecast. Considering the production performance of Pinghu gas reservoir in Pinghu field, this paper proposes four methods for prediction of its recoverable reserves, such as empirical formula method, material balance method, performance decline method and numerical simulation method. The prediction results show that these four methods are all practicable in application. In view of specific condition, one of these methods can be selected to use and/or several methods are applied for comprehensive evaluation of such a reservoir.

Key words: Pinghu field, condensate oil, recoverable reserve, condensate gas reservoir, prediction, forecast
