This proppant is refined from silica sand and polymer material through many production processes by scientific technology. It is especially applicable to the hydraulic fracturing measure for shale gas and dense oil & gas reservoir. It can effectively reduce proppant insertion into shale gas and dense oil & gas reservoir and keep the fissure width stable. Due to the fact that resin coated silica sand proppant has the features of low density, high strength and low friction, it can be transmitted from a distant area and be applicable to the multi-section hydraulic fracturing operation of the horizontal wells. It can effectively decrease the hydraulic fracturing cost and prevent some fragments of broken sand from migrating to avoid causing harm to the fissure conductivity.

Outstanding features: low density, high strength, low friction, insertion resistant, preventing some fragments of broken silica sand from moving.
