摘要：清海水压裂时通过系送大排量压裂液在储层中形成主裂缝为主干的黎缝网络，主裂缝内支撑剂的错置状况直接影响油气并的产能。采用自主设计的大型可视化平板裂缝装置来研究大排量泵送时主裂缝内支撑剂的输送规律，建立了相应的数值模型模拟了砂提在不同时刻的错置形态，并分析了滤流对支撑剂销置的影响规律，为滑海水压裂时主裂缝内支撑剂的有效铺置提供一定的理论指乎。研究表明，滑溜水压裂时支撑剂在主裂缝内的铺置规律与小排量压裂时不同：支撑剂首先在主裂缝入口处形成一个较低的砂提，而在距入口较选处形成一个较高的砂堤，之后才一层一层周期性的覆盖在两处砂堤之上，直到达到最终的平衡高度；大排量压裂时易引起滤流，将主裂峰进口端暂时沉降的支撑制重新卷入裂峰深处，形成类似“参云状” 的沉降结构；数值模拟与物理实验模拟得到的支撑剂错置结果相仪，证明了研究的数值模型具有一定的实用性，

Abstract: When slick water fracturing is carried out, a fracture network with the major fracture as the trunk is formed in the res-ervoir by pumping fracturing fluid at high flow rate, so the laying situations of proppant in the major fracture has direct effect on the a e ae e en ea aad sa se ao the transportation laws of proppant in the major fracture in the process of high rate pumping, The corresponding numerical model was established to simulate the laying form of sand bank in different time. And the influential laws of turbulence on the laying form of prop pant were analyzed. It provides the theoretical guide for the effective laying of proppant in the major fracturing in the process of slick water fracturing. It is indicated that the laying law of proppant in the major fracture during the slick water fracturing is different from that during low fow rate fracturing. The proppant firstly generates a lower sand bank at the entrance of the major fracture and a higher sand bank farther from the entrance, and then covers both sand banks periodically layer after layer until the balance height is ultimately
