A high strength and high permeability sand sleeve

High strength, high permeability sand sleeve provided by this invention, comprises a tubular body adapted to be inserted around the wall, the tubular body comprises the following components: aggregate particles, the resin film coated on the surface of the particles and aggregates polythiol curing agents for curing the resin film, the resin film is an epoxy value of an epoxy-modified 0.23-0.56eq / 100g silicone resin film, the resin film and the aggregate particles 0.5 to 10 percent by weight: 100, polythiol curing agent to the weight percent of the resin film is: 15-20: 100. Sand having a high strength and a high oil-permeable water cut-off properties can be applied to the sleeve wall surrounding the sand.
