Delay water absorption expansion leakage blocking agent and preparation method thereof

The invention relates to a preparation method of a leakage blocking auxiliary agent in the field of oil field well drilling. The method comprises the following steps of (1) firstly weighing a certainamount of acrylamide, 2-acrylamide-2-methallyl sulfonate, N,N-methylene bisacrylamide and initiators; putting the materials into a reactor; adding the corresponding amount of distilled water and ice water bath; performing stirring to complete dissolution; (2) slowly adding enhancing agents and hydrophobic monomers; performing low-temperature stirring; introducing N2 for protection; (3) lowering the temperature to 0 to 10 DEG C; dripping an initiator solution; (4) after the dripping completion, continuously performing stirring for 15min; raising the temperature to 50 DEG C; performing still state reaction for 2 to 5h to obtain an elastic gel body; (5) taking out the elastic gel body; performing vacuum drying at 60 to 90 DEG C and shearing to obtain a delay water absorption expansion leakageblocking agent product. The method has the advantages that the obvious delay expansion features are realized; the expansion in a shaft is slow; after reaching the leakage zone, the expansion can be continuously performed, so that the leakage zone can be effectively improved; the restoration effect is achieved.
