摘　　要：随着苏里格气田气井数量的逐年递增,传统人工开关井方式作业频繁、劳动强度大,且受天气、外协等诸多因素影响,工作效率较低,不能满足目前气田生产需要。因此,研发了一种远程智能开关井技术,由控制系统和远程智能开关井装置联动,实现气井智能化生产。在苏里格气田进行了现场试验,结果表明:(1)该技术可以监测井口实时运行参数,调节阀门开度,实现高压气井的现场手动、现场自动、远程智能开关井功能;(2)可以设定开关井时间,实现气井中后期间歇井智能管理功能,满足气井全生命周期的生产要求;(3)可以设定自保护压力值,实现紧急截断功能,确保气井安全生产;(4)该技术的应用可以降低员工劳动强度,提高生产效率。As the number of gas wells in Sulige gasfield increases year by year.The traditional manual well switching method needs frequent operations,increases labor intensity,and is affected by many factors such as weather and coordination.The work efficiency is low and cannot meet the current gasfield production needs.Therefore,a remote intelligent well switching technology has been developed,which is linked by a control system and a remote intelligent well switching device to realize the intelligent production of gas wells.Field tests are conducted in the Sulige gasfield,and the results shows that,(1)the technology can monitor real-time operating parameters of the wellhead and adjust the valve opening to realize on-site manual, on-site automatic, and remote intelligent well switching functions of high-pressure gas wells.(2)The well switching time can be set to realize the intelligent management of intermittent wells in the middle and late stages of gas wells. Finally, this technology satisfy the production requirements of the gas well's full life cycle.(3)The self-protection pressure value can be set, and the emergency cut-off function can be realized to ensure the safe production of gas wells.(4)The application of this technology can reduce the labor intensity of employees and improve production efficiency.
