The invention relates to a water and leakage plugging material of retarded crosslinking gel wrapping high valence metal ions, which can plug crack and cave leakage stratum, and the preparation of wrapped particles is easy to realize batch production. The technical scheme comprises the following steps: adding acrylamide, styrene, zirconium tetrachloride and N,N-methylenebisacrylamide into deionized water, adding initiator after dissolving, standing for 1hour at room temperature to obtain gel, pelleting, stoving and screening to obtain solid-phase particles; adding Span-80 into dimethylbenzene to prepare an oil phase; dissolving polyvinyl alcohol into deionized water to prepare an aqueous phase; adding the solid-phase particles into the aqueous phase, uniformly mixing, adding the mixture into the oil phase, fully stirring to form an inverse phase suspension, evaporating under 100-110 DEG C to remove water, filtering, washing and drying to obtain wrapped particles, and optionally wrapping again; adding the particles and stabilizer into an HPAM (hydrolyzed polyacryamide) aqueous solution to obtain fixed gel. The production of the material is easy to operate and is low cost, the time for gel forming is long, and the material has the characteristics of less filter loss, good leak tightness and good stability.
