Application of Integrated Directional and Guide Drilling Technology in Deep Coalbed Methane
Journal of Physics: Conference SeriesAbstract Deep coalbed methane is characterized by deep burial, complex and diverse microstructures, significant lateral variations in reservoirs, and the development of internal interlayers. Current seismic exploration methods suffer from severe high-frequency signal attenuation in coal layers, resulting in low seismic resolution, which ...

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).
