天然气采输已在我国各大油气田发展数十年，目前大多气田已经处于开发后期，压力低、产量低、含水高已经成为开采的首要难题。本文首先介绍了我国目前采气工程技术发展现状，并分析了采气工程技术的发展意义，简要介绍了泡沫排水采气、氮气气举排水采气、涡流排水采气、速度管柱排水采气等现有采气技术原理，最后探讨了我国采气工程技术未来发展趋势，希望能为采气工程相关人员提供参考和帮助。“,”Natural gas production and transportation has been developed for decades in China’s major oil and gas fields. At present, most of the gas fields are in the late stage of development. Low pressure, low production and high water cut have become the primary problems of exploitation. This paper first introduces the current development of gas production engineering technology in China, and analyzes the significance of the development of gas recovery engineering technology. It briefly introduces the existing gas recovery technology principle, such as foam drainage and gas recovery, nitrogen gas lift drainage and gas recovery, vortex drainage gas recovery, velocity pipe drainage and gas recovery, and finally discusses the future development trend of China’s gas production engineering technology. Hope to provide reference and help for relevant personnel of gas production engineering.
