In the process of coal seam gas gathering, some remote gathering stations by natural pressure of raw gas well cannot realize gas gathering and transportation, gas must be pressurized before gathering. Based on this problem, the application of Lanyan skid-mounted screw compressor Hudi block-base was taken as example, process design, equipment selection and technical characteristics of skid mounted screw compressor were analyzed, the end of a supercharged new technology was summed up, the technology can effectively solve the outlying block gas gathering problems in Jincheng Mining Area.
