Title:
SELF-SUSPENSION HYDRAULIC FRACTURING COATED PROPPANT HAVING TARGETING FUNCTION, AND PREPARATION AND APPLICATION
Document Type and Number:
WIPO Patent Application WO/2021/087658
Kind Code:
A1
Abstract:
The present invention provides a self-suspension hydraulic fracturing coated proppant having a targeting function, and preparation and an application. The proppant comprises: A) particles existing in an amount of 70-99.99% of the total weight of the proppant, and B) a nanometer particle enhanced porous composite material coating with which the surfaces of the particles are coated, and existing in an amount of 0.01-30% of the total weight of the proppant, wherein nanometer particle enhanced porous composite materials comprise nanometer particles (preferably, the weight of the nanometer particles is 1-50% (preferably, 10-20%) of the total weight of the nanometer particle enhanced porous composite material coating) and a porous composite material. Compared with a functional coated proppant produced by means of a traditional process, the materials such as resin used in the present method are derived from industrial production, the nanometer particles are creatively added to improve the performance of the proppant, and the method has a more simplified operation process and a lower production cost.
