Tóm tắt

In the later stages of shale gas well development, liquid accumulation in the wellbore became a significant problem. It restricts gas production and sometimes even causes well shutdowns due to water flooding. Foam drainage and gas recovery technology is an economical and convenient deliquification method, yet its stability has remained a challenge. Developing a highly efficient and stable foam drainage system for complex shale gas well environments is of great significance for enhancing shale gas production. This study focused on developing a nanoparticle-enhanced foam drainage system (TK5). KH-550 modified nano-SiO
