The invention provides a cement-squeezing pipe column and oil well maintenance equipment. The cement-squeezing pipe column comprises a first injection pipe, a second injection pipe, a compression pipeand an input pipe; the top end of the first injection pipe communicates with a stock pump through the input pipe; a gas pump communicates with the first injection pipe through the compression pipe, asecond control valve is arranged on the compression pipe, and a pressure gauge is arranged on the compression pipe between the second control valve and the first injection pipe; a third control valveis arranged at the bottom end of the second injection pipe; and the second injection pipe is formed by a plurality of intermediate pipes which are sequentially connected, and the adjacent intermediate pipes are detachably connected. The air tightness of the second injection pipe is ensured so as to avoid the situation that gas escapes through the adjacent intermediate pipes when injected into thesecond injection pipe to squeeze cement slurry in the second injection pipe, the pressure borne by the cement slurry is sufficient, a lot of the cement slurry is squeezed out through leakage holes, and the sealing effect of a casing is good.
