摘要(Abstract)：

为评价页岩储层压裂后形成的复杂裂缝的网络导流能力,改造常规裂缝导流仪,设计适合评价页岩裂缝网络导流能力的导流室,利用大理石和高硬度支撑剂组建不同结构的裂缝网络模型,进行裂缝网络导流能力实验,分析不同形态裂缝对裂缝网络导流能力的影响.实验结果表明:当裂缝宽度接近天然裂缝宽度时,平行于渗流方向的垂直裂缝对导流能力影响最大.现场施工时可使用较大铺砂浓度以增加裂缝宽度;压裂设计优选目标依次为平行于渗流方向的垂直裂缝、平行于渗流方向的水平裂缝和垂直于渗流方向的垂直裂缝.该研究结果为页岩储层压裂施工提供理论参考.

关键词(KeyWords)：页岩;裂缝网络;导流能力;缝网模型;正交裂缝;裂缝宽度
