摘　　要：连续油管气举是油气井井筒排液最主要的措施,主要用于油气井投产诱喷及气井积液停喷后的诱喷复产。目前,现场常用的作业方式为逐级增加注气深度,进行不同深度处的定点注气。为了保证气举效果并指导现场作业,需要对注气深度、注气压力与注气量等参数进行优化设计。通过分析作业特点,提出了一种连续油管逐级定点气举排液的工艺参数优化设计方法。该方法在现场已有多井次应用,效果良好。Gas lift by coiled tubing is the most important measure of wellbore unloading to induce oil and gas wells flowing.At present,the common operation is to increase the running depth of coiled tubing step by step and inject nitrogen at each depth.In order to ensure the gas lift effect and guide the field operation,the parameters such as gas injection depth,gas injection pressure and gas injection rate need to be designed.By analyzing the operation characteristics,this paper puts forward a kind of parameter design method of gas lift for wellbore unloading by coiled tubing.This method has been applied in many wells and achieved good results.
