The invention provides a foamed acid washing technological method for a horizontal well. With two packers at a horizontal well segment installed and foamed acid washing liquid poured from an annulus, the acid liquid flows outside a sieve tube, thereby enhancing the flushing and unclogging effects on mud cakes of a drilling well. With the temporary clogging effect of foam on a high permeability position and the low density characteristic of the foam used, the acid liquid leakage can be effectively reduced; and at the same time, with the high carrying capacity of foamed liquid and the expansion energy of nitrogen gas used, acidized solid particles and residual acid can flow back, thereby avoiding the secondary sedimentation damage, solving the problems of acid liquid leakage and incomplete residual acid backflow in the conventional acid washing process, and effectively improving the acid washing effect. In the technological method, the reaction between the foamed acid washing liquid and the mud cakes of the drilling well is carried out in two steps: firstly, displacing the foamed acid washing liquid to the horizontal well segment, and shutting the well for reaction; and then, displacing the unreacted foamed acid washing liquid to the horizontal well segment, inversely squeezing the foamed acid washing liquid into the stratum, and shutting the well for reaction. The invention is especially suitable for relieving the well drilling damage of a low-pressure leakage horizontal well.
