采用气压举升，是现代采油过程中经济效益最好的采油方法，气举可以不受油井深度的限制，注入气可以自上而下逐次通过各级气举阀深入液体内，使油管底部以上的液体重量变轻，并降低对油层的回压，从而保证油井顺利连续生产。
技术性能：
1、工作温度：可耐30℃-120℃
2、波纹管内充气压力：8.0-10.0MPa
3、波纹管外承受最大工作压力：45-50MPa

Gas lift is the best economic recovery method in the modern oil production process. Gas lift can not be limited by the depth of oil wells. Injected gas can penetrate into the liquid from top to bottom successively through all levels of gas lift valves, thus lightening the liquid weight above the bottom of the tubing and reducing the back pressure on the reservoir, thus ensuring the smooth connection of oil wells. Continue production.
