METHOD FOR LINING OF INNER SURFACE OF LIFTING PIPES OF OIL AND HAS WELLS WITH USE OF INSERTION PIPES WITH BALLOONING ABILITY

摘要

A method for lining of inner surface of lifting pipes (LP) of oil and gas wells through placing to those of inner plastic insertion pipes being subjected to ballooning. Just over production tree of the well one places thermo-press-extruder and forms reinforced with electro-conductive cables in heat-resistant insulation profiled with U-like depressions plastic insertion pipe, this one at outlet from extruder one lowers just to the inner space of the LP.
