FIELD: mining.
SUBSTANCE: invention relates to mining industry and can be used for operation of problem blocking wells with sucker-rod pumps. The method involves back-and-forth movement and rotation of a sucker-rod string. Downward movement speed of the sucker-rod string changes proportionally to load variation on a wellhead stock. Travel length of the sucker-rod string can be changed proportionally to load variation on the wellhead stock. Rotation of the sucker-rod string can be performed continuously.
EFFECT: possible elimination of blocking of a sucker-rod string without any disassembly of borehole equipment.
