Abstract: Influence of ASP system on the fracture conductivity of alkaliresistance resin sands and quartz sands was studied. The results showed that compared with the weak base, the dissolution of strong base on the quartz sands was more serious. And the damage percentage of the particles was higher. Therefore the reduction of conductivity of fractures packed with sands was larger. Compared with quartz sands, there was little difference between the dissolution of weak base on the alkaliresistance resin sands and that of weak base on the alkaliresistance resin sands. So it was the same to conductivity. With the increase of closing pressure, the conductivity of quartz sands and alkaliresistance resin sands were both weakened. But the reduction degree became gradually small. Compared with quartz sands, the influence of closing pressure on the conductivity of fractures packed with alkaliresistance resin sands was weak. And the fracture conductivity capacity was stronger.
