本方案的总集输工艺流程的确定是根据本气田的综合情况，借鉴其它煤层气地面

The determination of the overall gathering and transportation process of this scheme is based on the comprehensive situation of this gas field, drawing on other coal bed methane surface gathering and transportation processes, and analyzing the overall technological process of various low-yield and low-pressure coal bed methane fields. CBM gathering and transportation process flow of “separation gathering and transportation, multi-well low-pressure gas gathering, simple well single metering, multi-well single pipe series connection, centralized pressurization, centralized dehydration treatment and external transportation”.

The determination of the total set transmission process of this scheme is based on the comprehensive situation of this gas field, learn from the other coal seam gas ground collection and transmission process, analyze the total process of various low-yielding low-yield low-voltage coal seam gas fields, after repeated demonstration, simplification and optimization, and finally determine the use of "shard collection, multi-well low-pressure gas collection, single-well simple metering, multi-well single-pipe cross-linking, concentrated supercharged, centralized dewatering treatment and external transmission" coal seam gas transport process.

According to the comprehensive situation of the gas field and other coalbed methane surface gathering and transportation technologies, the total gathering and transportation technological process of this project is determined. After repeated demonstration and simplification, the "slice gathering and transportation, multi well and low pressure gathering, single well simple measurement, multi well and single pipe connection, centralized pressurization, centralized dehydration treatment and Coal bed gas gathering and transportation process of "export".
