摘要:

目前全世界凝析气田开发主要采用衰竭和注气两种开发方式。由于诸多条件的制约注气,应用受到限制;衰竭式开采凝析油采收率低,对于凝析油含量高的气藏开采效果不好。凝析气藏注水开发是一新的开发方式,国内对此方面研究较少,值得探索。以大港板桥废弃凝析气藏室内岩芯注水驱替实验为基础,对水驱的可行性及其机理进行了探讨。实验表明:凝析油和天然气的采收率最高可分别增加3.39%、10.11%;较高速度下注水效果好于在低速下水驱效果;存在一最佳注水量值;在废弃压力条件下注水效果优于复压后注水效果。

Abstract:

At present,the methods of developing the gas condensate reservoir are mainly depletion and gasinjection. Because of being restricted by lots of applied conditions, the use of gas injection is restricted; the depletion leads to lower recovery of condensate oil and the effectiveness of development is worse to gas reservoir with the high content of condensate oil. Water flooding is a new developmental method for gas condensate reservoir, the research on that is few, so it is worth probing. On the basis of the inhouse core flooding experiment of an abandoned condensate gas reservoir of Banqiao gas condensate reservoir by water flooding, the feasibility and mechanism of water flooding gas condensate reservoir are explored. The results of the experiment shows that the improved recovery of condensate oil and gas are 3.39% and 10.11%, respectively the effictiveness of water flooding at high speed is better than that at lower speed, the effictiveness of water flooding at lower pressure is better than that at higher pressure.
