基于旋流机理的排水采气技术研究进展

Research Development of Unloading in Gas Well Based on the Swirling Mechanism

天然气生产过程中经常会出现井底积液问题,现有的排水采气方法很多,而采用旋流机理解决天然气井井内积液问题具有投资小、使用维护方便等优点,因此逐渐成为研究热点。本文对旋流工具排水采气技术的国内外发展现状进行论述,并对进一步需要研究的问题进行探讨,以对国内油气田的开发起到促进作用。

Liquid loading in gas well is often a main problem in gas production.Now there are many methods for unloading.However,it has many advantages by using the mechanism of swirling flow to solve the problem,such as low cost and convenient maintenance.So the technology of swirling tool in gas well has become the research hot point.In this paper,the development of unloading technology by using swirling tool domestic and abroad is discussed.Then the tendency of it is described in order to promote the gas production in oil/gas field.
