Summary:Anti - well drilling export buffer that circulates of gas lift comprises outer wall pipe (1), core pipe (2) and connecting pipe, and the connecting pipe is connected with rig row cinder notch, and all weld on steel sheet (4) the rear end of outer wall pipe (1) and core pipe (2), and core pipe (2) are in the inside of outer wall pipe (1), and the top of core pipe (2) is sealed, and evenly distributed has a plurality of through -holes (3) on the wall of core pipe (2), and the connecting pipe sees through steel sheet (4) and core pipe (2) intercommunication. Compared with the prior art, owing to adopted foraminiferous core pipe, high -pressure aqueous vapor is passed through the tubular one -tenth of the round hole directive outer wall buffering on the core pipe and is flowed out safe and reliable forward.
