| titleOfInvention | A kind of proppant and preparation method |
| abstract | The invention discloses a proppant and a preparation method. The proppant includes proppant particles and a coating coated on the proppant particles; the coating is made by spraying and soaking the coating treatment liquid on the proppant particles; the coating treatment liquid is made of organic silicon A compound, a silane coupling agent, a co-solvent and a solvent, wherein, based on the weight of the solvent as 100%, the content of the organosilicon compound is 0.1% to 50%, the content of the silane coupling agent is 0.1% to 30%, and the content of the co-solvent is 0.1% to 10%. The proppant of the present invention can reduce the adsorption of substances such as fracturing fluid and crude oil on the surface of the proppant, improve the conductivity of fractures, and has simple formula, low field application conditions and low construction cost. |
