主　　题：Self-suspension Coating Proppants Hydraulic fracturing process Liquid conductivity 

摘      要：Proppant is a key material in the hydraulic fracturing process,which has been widely used in unconventional oil *** proppants are easy to sedimentate and accumulate at the entrance of shale fracture,which will block the diversion of water,oil and *** proppants(CPs) are fabricated by coating resin on normal ceramic proppants through a simple method,which is dramatically enhanced the supporting properties in shale fracture and easy to scale *** with uncoated ceramic proppants,the self-suspension ability of CPs is ~11 times higher,which are able to migrate and distribute farther and deeper inside the *** the same time,Coating enhanced the 23.7% of adhesive force in maximum,which makes the CPs easier to adhere on the fracture surface to supportthe shale ***,the liquid conductivity of CPs is 60% higher than uncoated ceramic proppants at13.6 MPa *** method is expected to fabricated varieties of proppantsfor shale fracture supporting to improve the exploration of unconventional oil and gas resources.
