[0001] The utility model relates to the technical field of offshore oil equipment, in particular to an arrangement scheme of offshore on-line profile control equipment. Background Technique

[0002] At present, in the oil industry of our country, offshore oil production has entered the tertiary oil recovery stage, and a large number of profile control equipment are needed to inject agents into oil wells. However, most of the current profile control equipment is still designed for onshore oil production, with large volume and inconvenient movement, and is not suitable for offshore platforms.
