Novel high-temperature resistant inorganic particle-gel compound double-liquid blocking agent and blocking method thereof

The invention relates to a novel high-temperature resistant inorganic particle-gel compound double-liquid blocking agent and a blocking method thereof. The novel high-temperature resistant inorganic particle-gel compound double-liquid blocking agent is a black brown solution formed by dissolving and mixing a first working solution and a second working solution in normal-temperature stratum water, wherein the first working solution consists of sodium nitrohumate and formaldehyde and is black brown with little viscosity; the second working solution consists of resorcinol, HPAM, graphite particles and CMC, and the supernatant solution is black with little viscosity and without irritant smell; the two components of the first working solution and the four components of the second working solution are as follows based on total weight: 4-12% of sodium nitrohumate, 1.2-2.4% of formaldehyde, 1.65-3.85% of resorcinol, 0.015-0.035% of HPAM, 0.15-2% of graphite particles and 0.2-0.5% of sodium carboxymethylcellulose.
