The utility model provides a mix rare system. This mix rare system includes: rare pump and adjustable glib talker mix, wherein, adjustable glib talker respectively with it connects to mix rare pump and well head. The utility model discloses a be connected the adjustable glib talker that can adjust glib size between the rare pump of mixing of mix rare system and well head for when oil well yield reduces by a wide margin, can be through the adjustable glib further control that realizes mixing rare volume, solved mix rare volume when the converter adopts minimum frequency of operation and mix rare than on the high side, the higher problem of viscous crude manufacturing cost.
