The overall collection and transportation process of the scheme is determined based on the comprehensive situation of the gas field, referring to the surface collection and transportation process of other coalbed methane, and analyzing the overall process of low production and low pressure. Coalbed gas field. The process flow of coalbed methane gathering and transportation is "separate gathering and transportation, multi well low pressure gas gathering, single well single well metering, multi well single pipe series connection, centralized pressurization, centralized dehydration treatment and external transportation".
