Optimization and application of sand bailing technology for coalbed methane horizontal wells

Optimization and application of sand bailing technology for coalbed methane horizontal wells

Objective and Methods Coalbed methane (CBM) horizontal wells face challenges such as sand accumulation in completion strings, pipe wall scaling, and pump sticking, leading to declined CBM production or shutdown of these wells. This severely restricts continuous, stable CBM production. Removing pulve...
