    • 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.
    • 公开了一种将支撑剂置于从井眼形成在地层中的裂缝中的方法。 该方法包括通过井眼喷射第一处理流体以引发地层中的断裂; 通过井筒注入包含由支撑剂制成的颗粒状混合浆料的第二处理流体; 所述颗粒混合物包含至少第一量的具有约100至5000μm的第一平均粒度的颗粒和至少第二量的第二平均粒度小于第一平均粒度的约2-3倍的颗粒 ; 以及与所述颗粒状混合浆料一起形成多个富支撑剂富集簇,其通过形成开放通道的无支撑剂区域间隔开。
