摘　　要：介绍了井下节流工艺原理、节流工具的技术指标、适用范围以及在川渝气田中的应用情况,结果表明,井下节流能控制气井产量,取消单井地面水套加热炉,节约加热用气,减少井岗管理人员,降低集气支线管线压力等级,达到降低气井开采成本之目的,具有明显的技术经济和社会效益。This paper introduced the principle of subsurface choke technology technical index of choke tool and range of application. Through field application in Chuanyu region, the results show that the subsurface choke technology can control the production of gas well, cancel the surface heater of single well, reduce the pressure grade of gas line and production cost of gas well. It has the obvious economic and social benifit.
