高浓度泵注起泡剂在低压低产页岩气井的应用

Application of High-Concentration Foaming Agent in low-pressure and low-production Shale Gas Wells

针对页岩气井在生产后期因水平段积液和地层压力不足影响产量的问题,提出一种适用于低压低产页岩气井的治理方法,在分析气井生产特征的基础上,确定高浓度泵注起泡剂的选井原则,通过不断优化调整设计参数,增产稳产效果显著。

To address the issue of decreased production in shale gas wells due to fluid accumulation in the horizontal section and insufficient formation pressure during the later stages of production,a method suitable for low-pressure and low-production shale gas wells is proposed.By analyzing the production characteristics of gas wells,the selection principles for wells using high-concentration foaming agents are determined.Through continuous optimization and adjustment of design parameters,significant improvements in production and stabilization are achieved.
