Study on Resin Coated Sand Proppant Used for Oil Production

A method of preparing precured resin coated sand particles was developed. The effects of resins dosages, plasticizer and coupling agent on the sphericity, roundness, crush resistance and flow conductivity of pre-cured resin coated sand were also discussed. Compared with raw sand, the sphericity and roundness of this resin coated sand particles is higher. It also possessed excellent properties to company sample, such as better resistance to crushing, as well as higher short term flow conductivity. By use of the resin coated sand, the cost could be reduced, and the yield of raw oil will be increased. It is a promising method of modified sand in field of hydraulic fracturing treatment.
