中文摘要：

川西须家河气井见水后产水量迅速上升,易导致水淹停产。气藏高温、高压、超深的特征制约了常用排水采气工艺的应用。在DY1井引入电潜泵排水采气工艺,针对大斜度深层气井开展设计和施工工艺优化,评价排水采气效果,分析故障原因,认为电潜泵排水采气工艺能满足该井连续高强度排液要求。但是,受机组振动和地层流体腐蚀等因素影响,电潜泵排采工艺技术在深层气井中应用风险较大。

英文摘要：

The Xujiahe formation gas well is prone to be flooded production suspension after produce water,the characteristics of high temperature,high pressure and ultra-deep of the gas reservoir restrict the application of common drainage gas recovery technology.Through the introduction of electric submersible pump drainage gas recovery technology in the DY1 well,the design and workover process optimization of the highly deviated well gas well was developed,the drainage effect was evaluated and also the fault cause was analyzed.Finally,it could be concluded that the ESP drainage technology is fit the demand of the continuous high strength liquid discharge,but influenced by the factors such as unit vibration and corrosion,the ESP technology has greater risk in the application of the deep and high water production gas well.
