The invention provides a natural flowing mechanical production integrated pipe column. The natural flowing mechanical production integrated pipe column provided by the invention comprises an oil extraction rod, an oil pipe, a water-gas injection valve, a packer, a sleeve, a rod pump and a rod pump supporting joint, wherein the sleeve is positioned in an oil well; the sleeve externally sleeves the oil pipe; the water-gas injection valve and the packer are both positioned in the oil pipe; the water-gas injection valve is higher than the packer in the oil pipe; the opening-closing state of circulating holes in the water-gas injection valve is changed along with the pressure state of the water-gas injection valve; the oil extraction rod, the rod pump and the rod pump supporting joint are sequentially arranged in the oil pipe in a direction from a well opening to a well bottom; the upper end of the rod pump is connected with the lower end of the oil extraction rod; the rod pump can be inserted into or detached from the rod pump supporting joint; the natural flowing mechanical production integrated pipe column is in a mechanical oil production state when the rod pump is inserted into the rod pump supporting joint. The natural flowing mechanical production integrated pipe column provided by the invention has the advantages that the natural flowing oil production and mechanical oil production are realized by means of putting the self-flowing mechanical production integrated pipe column in the oil well, so that the operation procedures are reduced, the operation efficiency is improved and the production cost is reduced.
