    摘要: A method of placing proppant into a fracture formed in a subterranean formation from a wellbore is disclosed. The method comprises injecting through the wellbore a first treatment fluid to initiate the fracture in the subterranean formation; injecting through the wellbore a second treatment fluid comprising a particulate blend slurry made of proppant; the particulate blend comprising at least a first amount of particulates having a first average particle size between about 100 and 5000 μm and at least a second amount of particulates having a second average particle size between about three and twenty times smaller than the first average particle size; and forming with the particulate blend slurry a plurality of proppant-rich clusters spaced apart by proppant-free regions forming open channels.
