Device for continuously condensing and recycling gas-liquid oil in oilfield

The utility model discloses a device for continuously condensing and recycling gas-liquid oil in an oilfield. The device comprises a gas inlet pipe, main and auxiliary condensing heat-exchanging devices and an oil discharge pipe, wherein a gas path switching valve is arranged on the gas inlet pipe; the gas inlet pipe is connected with the upper ends of oilfield gas pipelines arranged in the main and auxiliary condensing heat-exchanging devices; the lower ends of the oilfield gas pipelines are respectively connected with the oil discharge pipe, a drain pipe and an exhaust pipe; heat exchange liquid pipelines contacting with the oilfield gas pipelines are arranged in the main and auxiliary condensing heat-exchanging devices; inlet and outlet pipes are arranged on the heat exchange liquid pipelines and respectively connected with a refrigerant circulation system and a high-temperature condensing agent circulation system through the switching valve; a gas-liquid separator is arranged on the exhaust pipe. According to the device, one of the main and auxiliary condensing heat-exchanging devices is used for condensing and recycling and the other one is used for defrosting, so that the gas-liquid oil can be continuously condensed and recycled through alternate switching use.
