Abstract: During the later development period of Jilake condensate gas field, both the production of oil and gas and the pressure decrease constently, production wells were closed or stopped successively. At present, the actual production capacity has larger difference with the original design, both the natural gas treatment devices of Triassic and Carboniferous are both under low load operation, the equipment capacity has not yet been fully used, which cause the devices′ operation cost high and economy poor. To change the production situation, the natural gas of Triassic and Carboniferous are considered uniformly by pressure mechanism, the process is simplified and the operation parameters of the two devices are adjusted appropriately. The built facilities were used best to treat raw material gas for meeting the requirements of water and hydrocarbon dew point of the natural gas transportation.
