The resin quartz sand proppant has the flexible characteristics of the coating layer,which can effectively reduce the contact stress between particles and between particles and the formation.Under the coating of the resin,the proppant does not migrate when the reservoir is broken. After being injected into the formation,it can form an overall filter layer with the characteristics of sand prevention,anti-spitting,and embedding in the formation. At the same time,it can reduce the migration of broken particles and maintain the conductivity of the fractures that have been formed.
