The invention provides a central tube liquid control tubular column of a horizontal well and a liquid control tubular column technique of the horizontal well. The horizontal well comprises a vertical well section and a horizontal section communicating with the vertical well section. The central tube liquid control tubular column comprises a packer, a central oil tube and a blocking part, wherein the packer is arranged in the horizontal well; the packer is provided with an oil recovery channel and has the functions of suspension, packing and releasing; the central oil tube is arranged at the lower end of the packer and extends in the horizontal section; the central oil tube communicates with the oil recovery channel of the packer and is provided with a porous section and an imporous section, and the porous section is provided with a plurality of through holes; the through holes are formed in the tube wall of the porous section of the central oil tube; and the blocking part blocks the end, away from the packer, of the central oil tube. According to the central tube liquid control tubular column of the horizontal well and the liquid control tubular column technique of the horizontal well, the purposes of water reducing and oil increasing of the horizontal well can be achieved.
