| 摘 要： | 我国己开发的气田中,大多数气藏均属于不同程度的有水气藏。气藏在开发过程中都会产出地层水或凝析液。产出液若不能及时排出,就会聚积在井底,严重时造成水淹停产。在天然气生产过程中如何配产以连续携液是十分重要的。以往有学者认为产水气井只要井底不积液则气井就具有能连续携液的能力。本文利用相应的模型公式进行理论计算得到温度、压力对气井连续携液影响规律。同时,对川西气田7口井各重要参数进行了敏感性分析从而得出天然气井连续携液的规律性认识,即:在产液量较小时,井筒中的压力损失较小,而温度损失较大,温度成为影响携液的主导因素,井筒中的最大临界流量出现在井口附近;随着产液量的增加,温度损失较小,压力损失较大,压力成为影响携液的主导因素,井筒中的最大临界流量出现在井底附近。这也说明低压气井最大临界流量易出现在井底,而高压气井最大临界流量易出现在井口附近。

| Abstract: | The formation water and condensed liquid are produced during developing gas reservoirs.If the fluids could not be promptly discharge,they would accumulate in the bottom hole to result in drown out and off production.It is important to liquids continuous removal and flowing back in gas production.The influence law of temperature and pressure on gas well liquid loading were obtained by corresponding formula.At the same time,the important parameters in seven wells of West Sichuan gas field were carried out sensitivity analysis and the law of gas well liquid loading was obtained. |
