Optimization Design of Deep-Coalbed Methane Deliquification in the Linxing Block, China
ProcessesThe production of deep-coalbed methane (CBM) wells undergoes four stages sequentially: drainage depressurization, unstable gas production, stable gas production, and gas production decline. Upon entering the stable production stage, the recovery rate of deep CBM wells is constrained by bottom hole flowing pressure (BHFP).
