FIELD: oil and gas production, particularly to remove sand plugs from gas and gas condensate wells during well operation and repair.
SUBSTANCE: method involves providing flushing pipes with hydraulic circulation valve, which opens communication of annular space defined by inner tubing interior and flushing pipes; lowering flushing pipes in well; substituting weighted flushing solution for one, namely for light-weight liquid; closing circulation valve; removing sand plug through flushing pipe string and removing thereof from well.
EFFECT: increased flushing reliability and sand plug removal efficiency.
