The utility model relates to an underground pipe column for plugging top gas channeling in fireflood oil extraction, in particular to a non-slips integrated pumping pipe column for the gas-sealing oil extraction. A jointed top cap of the pipe column is sleeved on an upper section oil pipe, the jointed top cap, a relevant guide pipe, a supporting connector, a phi 114 connecting hoop, a short sieve pipe, an upper packer, a bridging oil pipe, a lower packer and a centralizer are sequentially connected from the top to the bottom. The upper section oil pipe, a moving connecting hoop and a pumping oil pipe are sequentially connected, wherein the moving connecting hoop is arranged in the relevant guide pipe at the upper end of the supporting connector. The upper packer and the lower packer are of the same structure and are both composed of connecting hoops, pressing covers, sealing pieces and central pipes. The connecting hoops are threaded with two ends of the central pipes, and the sealing pieces are fixed in the middle of the central pipes through the pressing covers. The non-slips integrated pumping pipe column obtains that a plugging pipe column and the pumping pipe column descend into a well and ascend integrally, the packers are non-slips self-sealing packers, accidents of packers under the well are avoided, the packers can be guaranteed not to move along with an oil pumping pipe column, and a validity period of sealing is long.
