摘　　要：增压气举是气田开发后期低压低产积液气井一项重要的排液采气工艺,该采气工艺在提高气田采收率、提高气井开井率方面显得尤为重要。从靖边气田近年的开发实践出发,在理论与实际相结合的基础上论证了正举相对反举的优越性,优选出靖边气田氮气气举复产排液模型。Gas lift is an important technology of gas recovery by liquid drainage for the low-pressure low-output standing liquid gas well at the later development stage.The gas lift flowing back can enhance recovery and well working rate.In this paper,it was demon-strated that the normal circulation gas lift was better than the inverse circulation gas lift on the basis of combination of theory and prac-tice,models of nitrogen gas lift reproduction used by Jingbian gas field were optimized.
