The utility model provides an anti-airlock oil-gas multiphase pump and a tubular column. The utility model discloses an anti-airlock oil-gas multiphase pump. The plunger pump comprises a pump cylinderand a plunger arranged in the pump cylinder, a traveling valve is arranged at the lower port of the plunger; the upper end of the plunger is connected with an inner upper joint; a radial oil outlet hole is formed in the inner upper joint; the middle part of the pump cylinder is provided with a liquid inlet and exhaust hole which is radially through; an outer pipe is hollowly sleeved outside the pump cylinder; the upper end of the outer pipe is connected with an outer upper joint; a first annulus is formed between the outer wall of the pump cylinder and the inner wall of the outer pipe; an inner cavity of the pump cylinder is communicated with the first annulus through the liquid inlet and exhaust hole; the lower end of the outer pipe is connected with an extension pipe through a reducingconnecting sleeve, a gap is formed between the inner wall of the extension pipe and the outer wall of the plunger, the lower end of the pump cylinder is in threaded connection with the inner wall of the reducing connecting sleeve, the lower end of the first annulus is a blind end, the upper end of the first annulus is in a through state, and the oil outlet hole is communicated with the first annulus. According to the utility model, the phenomenon of airlock of the oil well pump is prevented. The problems of potential safety hazards of casing gas and environmental pollution in current oil wellproduction are mainly solved.
