Integrated methods of CBM recoverability evaluation:A case study from Panzhuang mine

Adaptive condition and existing problems of various methods of coalbed methane(CBM) recoverability evaluation are discussed in the paper.It is important to study the effective configuration of main geological factors.The combination of multifactor weighted analysis with reservoir simulation is an effective means to evaluate CBM recoverability.Based on systematic analysis of main geological factors of Panzhuang mine,the integrated evaluation of CBM recoverability is performed.
