Oil fracturing proppant is classified the petroleum fracturing proppant into 3 types: natural quartz sand, artificial ceramic fracturing proppant, resin coated fracturing proppant. And the resin coated proppant can be divided into two kinds: coated sand and coated ceramic sand. The natural quartz sand is generally used in shallow oil well because of its round sphericity is not good and the strength is low, but the cost is lowest. The artificial ceramic proppant usually used in moderate-depth oil well because its round sphericity is good, the strength is high, and it can povide a high flow conductivity and can resistant corrosion. The sand coated by resin can increased its stength and lowe the density, so the coated sand can replace the ceramic proppant to be used in the moderate-depth well. The research of resin coated ceramic proppants was few, and it is expensive, so it has not used in production now.
