The invention discloses a processing method for river sand proppants for shale gas fracturing, and belongs to the technical field of oil-gas field development. The processing method for the river sandproppants for shale gas fracturing comprises the steps of obtaining river sand, and screening the river sand differentially after desliming and cleaning of the river sand; obtaining the river with the SiO2 content of higher than 95%, and then performing primary winnowing, surface treatment and secondary winnowing to the river sand with the SiO2 content of higher than 95%; finally screening the river sand after secondary winnowing, and obtaining proppants in different grain sizes for shale gas fracturing; putting the proppants and slick water into a stratum, and filling the proppants and the slick water into fissures formed by fracturing; and keeping the fissures in the open state. According to the processing method, only the river sand is used as raw materials of the proppants, and the processing steps are simple; the utilization rate of the raw materials is high, and the processing cost is low; and the production cost of the proppants for shale gas fracturing can be reduced effectively.
