The invention discloses an oil and water well extraction and injection tubular column internally and externally wrapped with hot melting plastic layers and a manufacturing method of the tubular column. The inner wall and the outer wall of each extraction and injection steel pipe are wrapped with the hot melting plastic layers, and the extraction and injection steel pipes are in screw connection with each other through pipe couplings. As for a pipe opening gasket between pipe openings of every two extraction and injection steel pipes, an inner ring is in a slab shape, the outer ring is in a trapezoid with the larger outside and the smaller inside, and the trapezoidal outer ring of the pipe opening gasket is firmly embedded into a trapezoidal groove of the corresponding pipe coupling. The inner wall and the outer wall of the overall tubular column are both wrapped with plastic, no gas and no steel exposed point exist between the inner walls of the extraction and injection steel pipes and the hot melting plastic layers, and the condition that liquid and gas make contact with steel is obstructed. Owing to the fact that inner layer plastic and the outer layer plastic cannot fall off, the effect that the tubular column inner walls of full oil extraction wells and injection wells are completely resistant to corrosion is achieved, and the wear-resistant effect of the tubular column pipe walls is achieved, so that the service life of the overall extraction and injection tubular column is prolonged by 3-5 times, and the repairing-free periods of the oil and water wells are prolonged by 2-3 times. According to the extraction and injection tubular column, steel is saved, the oil exploiting cost is reduced, the failure rate of the oil wells is decreased, and working efficiency is improved.
