摘　　要：随着气井进入开采后期,地层能量有限,气水同产井和井筒内原有生产管串等因素的影响,严重制约着气井的后期生产,常规的压井修井作业会导致该井被压死而停产。为充分挖掘老井潜能,降低风险程度,使用连续油管作速度生产管串,减少气液滑脱损失。分析了国内首次使用50.8mm连续油管在作速度管串时的计算依据、现场作业配置和作业效果。这一新工艺已逐步成为现场气井改造的发展方向。Along with limitation of formation energy at later time of exploitation of gas well,influence by factors of wells of producing gas and water of former production string,it sustains production of gas wells seriously and convention workover by killing well will make the well to stop produce gas.To excavate potential capacity and low risk content,applying coiled tubing to be speeding string in gas well reduces gas and fluid surge lose.Calculating foundation,field operation collocation and operation result of it is analyzed and introduced at the first time.This new tech is to be developing orientation of reformation for gas well progressively.
