A drill-following reamer comprises an upper joint, a reamer body, a piston nozzle, a piston, a compression spring, a blade, a pin shaft and a limit stop. The upper part of the whole set of device is connected with a drilling tool through the upper joint, while the lower part is connected with a drill bit through a screw thread. During drill-following reaming operation, the liquid piston nozzle pumped on the ground produces pressure drop to push the piston to move downwards, a groove on the piston pushes a gear structure on the blade to rotate the blade outwards by using the pin shaft as the center when the piston moves downwards till the blade is limited by the limit stop, and then the blade is expanded to reach the maximum outside diameter to start the drill-following reaming operation. 78.6 percent of drill hole expansion rate can be achieved by using the drill-following reamer, so the drill hole expansion rate is high; the blade has the mechanical locking function and is not retracted due to the extrusion of the well wall, so the diameter of the reamed drill hole is regular; and because the drilling and the reaming are carried out at the same time, the drilling cost is saved.
