Beschreibung
Zusammenfassung:	FIELD: oil production, particularly vibration generating arrangements for boreholes or wells for stimulating production. ^ SUBSTANCE: device comprises bottomhole tool for applying impacts arranged in well borehole, lifting device connected to bottomhole tool and anvil. Lifting device has case for piston with through channel, valve and upper stop adapted to limit upward piston movement arrangement. Space between outer case surface and inner well surface is closed with packer. Over-piston space of lifting means is hydraulically connected with suction line of downhole equipment. Bottomhole tool is installed in container with support placed on the anvil and connected to the case. Container is provided with orifices for liquid. Container bottom serves as the anvil. ^ EFFECT: increased efficiency due to improved working ability thereof and reduced turnaround time. ^ 5 cl, 4 dwg
