提高凝析气藏采收率和气井产量新思路

目前我国多数凝析油含量中偏低的饱和凝析气藏,多用衰竭方式开发,有的已处于开发中、后期,提高凝析气井产量和气藏凝析油采收率已成为关键问题.着重介绍了三种提高单井产量和四种注气开发提高凝析气藏凝析油采收率的工艺技术.探讨了凝析气藏开发中、后期多种开发方式,针对性地提出了开发凝析气藏的三点意见.望能加强该类气藏开发中、后期的研究工作.

New Way to Improve Gas Well Production and Condensate Gas Field'S Recovery Factor

Most of the saturated condensate gas reservoirs with middle or low gas condensate are developed by depletion type. Some are in the middle or late period of development. How to improve gas condensate well production and the recovery of gas condensate in gas field has become a key problem. The article introduced three techniques to improve single well production and four ways to improve gas condensate recovery of condensate gas reservoir developed by injecting gas, then discussed some development schemes of condensate gas reservoir in the middle and late period and proposed purposefully three opinions about developing condensate gas reservoirs by water -flood. We hope that the study on this kind fields in the middle and late development period can get enough attention.
