FIELD: earth drilling.
SUBSTANCE: invention relates to field of fixing tubing (TBG) in operational column operated by rod pumping units. Method for tubing fixing with anchor in wells operated by a rod pump includes: descent tubing (TBG) with a pump and anchor into the well at a specified interval. Tension by tubing longitudinal force with subsequent fixation in this position by an anchor. The longitudinal force on the tubing is created by unloading the rods by stopping plunger mounted on the column at the bottom of rod pump cylinder.
EFFECT: simplification of TBG tension process due to mechanical tension and hydraulic or mechanical installation of anchor in the well.
