摘　　要：对带井下节流器的气井携液能力进行敏感性分析,研究影响气井携液能力因素,并分析井下节流对各参数的影响。研究发现:压力增大,携液能力增强;温度增加,气井携液能力降低;低压气井井口压力较大时,节流器无法节流降压,对没采取增压的气井应及时打捞。This paper analyzes the sensitivity of the fluid carrying capacity of the gas well with downhole throttling device,studies the factors affecting the fluid carrying capacity of the gas well,and analyzes the influence of downhole throttling on the parameters.The analysis shows that the fluid carrying capacity of gas well increases with the increase of the pressure,and decreases with the increase of temperature.For the low-pressure gas well,when the wellhead pressure is high,the throttling device cannot play the role of throttling and reducing pressure.The results of this study have some referential significance in the production of downhole throttling gas Wells.
