Summary: | The invention relates to the technical field of gas injection in oilfield development and is applied to separate injection of CO2. According to the device provided by the invention, a tee of the device is separately connected to a general pipeline and two branch pipelines, the general pipeline is connected to a valve, a flowmeter and a pressure meter, and an adjustable pressure reducer, a differential gage, a thermometer and an emptying valve are also mounted on the branch pipeline I or/and the branch pipeline II. A heat exchanger is arranged on the general pipeline or the branch pipelines. The adjustable pressure reducer comprises more than two throttling nozzles which are mounted in series. The adjustable pressure reducer is provided with a baffle plate in the downstream part, aligned toa nozzle, of each throttling nozzle. The thermometer is mounted on a mounting assembly. The branch pipeline with the adjustable pressure reducer is connected to a gas injection tree interface which is low in gas injection pr |
