| 摘 要： | 随着含水气田开采时间的增加和开发程度的加深,气井产水逐渐增多,造成油管压力损失增加,井口流动压力下降,严重时甚至造成气井积液,大大降低气井的采收率。因此了解气井出水阶段及带水采气条件,提早更换小直径油管的排水采气工艺,消除和延缓水患,以保障气田合理、高效的开发。通过研究高气液比气井临界携液产量模型,推导适合不同雷诺数范围的油管直径,为井下作业油管直径的选取及更换提供理论依据。

| Abstract: | With production time of aquifer gas field increased and development degree deepened,loss of tubing pressure increases,wellhead flowing pressure decreases, in severe case,even gas well liquid accumulates,gas production declines too fast and recovery of gas well is greatly reduced,for producing water of gas well gradually increases.However, to safeguard reasonable and efficient develop gas field,when conditions of effluent stage and producing gas with waterare understood,drainage gas recovery processis carrie... |
