The invention discloses a reversible gel consolidation plugging method. The method comprises the following steps: evaluation of the construction feasibility of a plugging material: judging whether the
granularity of a consolidation agent meets the requirement or not; in-situ preparation of consolidation
slurry: collecting parameters such as well leakage stratum depth, pressure, temperature and water output amount, determining the thickening time of the consolidation
slurry, adjusting the adding amount of a
retarder according to in-situ water, adding the
retarder into a water tank to be evenly stirred, sucking and mixing the consolidation agent and water according to a certain proportion through a batch mixing pump, pumping the mixture into a batch
mixing tank, conducting stirring in the batch
mixing tank for a certain time, and detecting the performance of the consolidation
slurry; the plugging process: preparing the consolidation slurry according to a designed amount, lifting a drilling tool to a certain height above a leakage layer, pumping the prepared consolidation slurry into a well, jacking the consolidation slurry into a stratum by using slurry to jack the drilling tool out, lifting the drilling tool to a safe well section, carrying out intermittent
extrusion according to conditions, further enabling a plugging agent to permeate into the leakage layer in a thickening process, closing the well and waiting for setting, opening the well for circulation, and downward putting a
drill plug to test the plugging effect.
