判别气田是否见水,是气藏开发的有效监测手段,能够为后期井网结构调整,储层改造,开采方式转变提供重要的参考依据。超高压凝析气田,因开展饱和度测试等具有较大风险,所以无法有效识别气水界面变化或水体运移情况。本研究以某超高压凝析气田某采气井X为例,通过采用RTA软件解释,数学推导验证和化验相结合的思路,提出系统判别气田见水的新方法。
Judging whether the gas field sees water is an effective monitoring measure for gas reservoir development and can provide important reference for structural adjustment of well pattern, reservoir reconstruction and transformation of mining methods in the later stage. EHV condensate gas fields are not able to effectively identify changes in gas-water interface or water movement due to greater risk due to saturation tests. In this study, a gas well X in an ultrahigh pressure condensate gas field was taken as an example. Based on the idea of RTA software interpretation, mathematical derivation and verification, a new method to discriminate gas seepage in gas field was proposed.
