| 摘 要： | 气顶油藏在开发过程中经常遇到气窜问题,研究气窜对改善油气田开发效果具有重要意义.凝析气顶油藏气窜特征与常规气顶气窜不同,凝析气顶气窜不仅表现为气油比和累产气量升高,其采出油组成和密度等特征都发生了较大变化,因此在气窜量分析和计算时要采用不同的方法.在常规气顶气窜量计算法的基础上,推导了适用于凝析气顶气窜量的气油比动态计算方法.通过实例进行了凝析气顶气窜量的计算.并与密度动态法比较,验证了该法的可靠性.

| Abstract: | Gas breakthrough happens frequently in the development of gas-cap reservoirs, and its research is of great significance in the oil -gas field development. The condensate gas breakthrough is different from the conventional gas breakthrough, with increased gas-oil ratio and total gas production, and with different surface oil composition and oil density, therefore, different method must be used in gas breakthrough analysis and computation. This paper proposes a new method based on the conventional gas breakth... |
