METHOD TO MAKE CONTINUOUS PLASTIC LIFTING PIPE FOR OIL WELLS

摘要

A method for making reinforced plastic lifting pipe for oil wells consists in that lifting pipe is made continuous, reinforced with braiding and with electro-conductive cables in heat-resisting insulation. At that the pipe is made just in well, through placement of thermo-press-extruder over production tree of well and connection of electric well pump and auxiliary electrically controlled equipment at lower end of pipe.
