This paper firstly analyzes the current situation and prospects of Chinese coalbed methane explo- ration and development, and then studies the coalbed methane reservoir porosity and fracture system character- istics, and analysis reservoir damage mechanism of coalbed methane drilling. Finally, to solve the difficulty of coalbed methane driUing reservoir protection, there are many coal bed methane drilling reservoir protection technology such as low solid or clay free drilling fluid, under balanced drilling technology, temporary plugging technology and the strengthening of the solid phase control.
