摘　　要：针对东海西湖水驱气藏井存在见水后积液或水淹严重,稳产难度大等问题,结合气井产水特征,开展气举措施工艺技术研究。通过典型井管流模型建立,优选注气参数、气举阀参数等参数,实现了东海气井气举排采参数的科学快速选取。在气举措施设计的基础上,对常规气举、打孔气举和氮气气举等工艺进行了优化及应用研究,形成了适宜东海西湖气井开采特征的气举措施配套工艺,对后续油气藏开采的排水采气措施提供了一定的借鉴意义。In view of problems of serious effusion or water flooding after water breakthrough and stable production in the wells of Xihu water drive gas reservoir in the East China Sea,combined with the characteristics of water production in gas wells,the gas lift is studied.Through the establishment of typical well pipe flow model,the parameters such as gas injection,gas lift valve are optimized,and the scientific and rapid selection of gas lift parameters is realized.On the basis of gas lift design,the proces-ses of conventional gas lift,perforated gas lift and nitrogen gas lift are optimized and applied,and the matching process of gas lift measures suitable for gas wells in the West Lake of the East China Sea is formed,which provides a certain reference for the drainage and gas recovery measures of subsequent oil and gas reservoir mining.
