邛西气田柱塞气举排水采气工艺优化分析

Analysis of the Optimization of the Plunger Lift Drainage Gas Recovery Technology in Qiongxi Gas Field,Southwest of Sichuan Basin

针对川西南部地区气田产水井增多、气井地层压力下降、老气田低产井数量上升等现状,尝试采用柱塞气举工艺改善气井开发效果。对应用效果进行评价,优选出研究区适宜实施该工艺的气井,控制气井递减率,以实现油田高效开发。

With the number of the water and gas well gradually increasing now in the southwest of Sichuan basin,and the formation pressure of gas well decreasing continuously,it is necessary to develop drainage gas recovery technology for improving low production wells in old gas field.Through analyzing the effect and evaluation of plunger lift drainage gas recovery technology carried out in the southwest of Sichuan basin,we optimize gas wells that are suitable to carry out plunger lift drainage gas recovery technology in order to control the rate of gas well production,and realize efficient exploit.
