【摘要】 苏里格气田随着逐年开发,低压低产井越来越多。此类井产能较差,部分存在严重积液,排水采气工艺已在该区块广泛应用,但是各类工艺的参数优化,以及不同类型、不同时期产水气井对各种工艺的适用性如何,仍是急待解决的现实问题。该区块应用较多的是泡沫排水采气和井下工具类排水采气(速度管柱、雾化和涡流工具),本文对其工艺原理、工艺应用、工艺优化与适用性分析和室内及现场实验研究现状进行了综述,并提出了目前该领域研究需要关注和待解决的相关问题。更多还原

【Abstract】 There are many low-pressure gas wells in the Sulige gas field.These wells have low production efficient and serious liquid loading problems.Various techniques have been utilized to solve this problem in the area,but their process optimization and applicability still need to be investigated.In this paper,we reviewed the principles,process optimization,applicability and experimental apparatus for four liquid unloading processes:foam,velocity string,atomization and swirl flow.更多还原
