FIELD: oil production industry. SUBSTANCE: this relates to gas lift extraction of oil from wells. For more efficient separation of gas from raw oil, device is provided with vibration setup made in the form of housing installed coaxially with magnetostrictive converter and rigidly connected with its core. Housing substantially increases area of vibrating surface which is in contact with raw oil flow and makes its action upon it more effective. EFFECT: high efficiency. 1 cl, 3 dwg
