The utility model belongs to coalbed gas mining technical field discloses a
wellhead coalbed gas screw compressor, including compressor host computer, motor,
gas pipeline system, oil pipeline
system, cooling
water circulation system and
control system, the compressor host computer is used to the low pressure coalbed gas of
wellhead collection carries out compression, the motor is connected with the compressor host computer through the shaft
coupling, is used for driving the compressor host computer, the
gas pipeline system is connected with the compressor host computer, is used for the air intake, compression, oil
gas separation and
gas supply of coalbed gas, the oil pipeline system is connected with the compressor host computer, is used for the circulation, cooling and
filtration of lubricating oil. The utility model effectively solved the problem that the traditional screw compressor is heavy and leads to the transportation and installation difficulty, greatly facilitates the transportation and deployment of equipment in the poor
road condition mountain wild
wellhead area, shortens the equipment installation period, reduces the installation cost, improves the efficiency of coalbed gas mining.
