Based on Binchang Dafosi coalfield geological characteristics of CBM, production systems of different water production and bottom-hole flowing pressure of CBM vertical wells is analyzed by using the CBM reservoir numerical simulation method. Velocity sensitive influence on critical flow is analyzed by velocity sensitive laboratory experiment results. According to the analysis of the above, the control parameters of CBM vertical wells production stages are quantified. The research results provides theory basis for fining production of the Dafosi coalfield.
