| 摘 要： | 在异常高压有水气藏开采过程中,地层水的侵入会形成"水封气",造成气井单井产能下降和单井动态控制储量急剧减少,严重影响该类气藏的最终开发效果。利用异常高压有水气藏水侵机理数值模拟模型,在研究水侵影响因素基础上,总结出一套异常高压有水气藏的水侵规律。研究结果对于制订合理的异常高压有水气藏开发技术对策,尽量降低"水封气"对气藏开发效果的影响,最终提高该类气藏的采收率意义重大。

| Abstract: | The encroachment of formation water into water-bearing gas reservoir with abnormal pressure can cause water sealing gas,leading to decline of well productivity and drastic reduction of the dynamic reserves controlled by individual well,finally affecting ultimate recovery.The regularity of water encroachment into water-bearing gas reservoir with abnormal pressure is presented through numerical simulation based on the study of water encroachment influence factors.This study has important significance to adopt... |
