摘　　要：针对苏里格气田在高压气井生产中不能远程开井的问题,研制了新型气井智能电动针阀,并将它无缝接入气井智能监控系统中。该针阀已完成13口井的安装调试,气井开井用时平均30min,大幅降低了人工工作量,阀门的调节精度由0.50%提高到0.05%,开启和关闭扭矩降至0.6N·m。Considering the difficulty in remote startup of the gaswell in Sulige Gasfield,a new type of intelligent electric needle valve for gas wells was developed and connected to gaswell’s intelligent monitoring system seamlessly.Applying it in 13 gaswells shows that the startup time of the gaswell can be shorten to only 30 minutes averagely and the artificial workload is reduced obviously together with the valves’improved regulation precision of 0.50%to 0.05%and the start/close torque can fall to 0.6N·m.
