摘　　要：采用滑溜水压裂可以形成更密布的网状裂缝,对于页岩气的流动,可以提供足够的导流能力,与水平井配套使用,可形成更大的裂缝网络和泄油面积,取得良好的开发效果。滑溜水压裂应该选取高脆性、高有机碳含量、低应力井段进行分簇射孔,施工中,使用大排量、大液量、小粒径支撑剂,低砂比、段塞式注入方式进行压裂。但滑溜水压裂砂比低,支撑剂用量大,携砂液(水)用量巨大,工艺技术有待进一步提高。Slickwater--based fracturing matched with horizontal wells may form larger fracture network and oil drainage area, achieving better development results. When it is adopted, clustering perforation should be completed in the low-- stress yet high--brittleness well section with high organic carbon content. However, due to low sand ratio and large dosages of proppant and sand--earrying fluid in slickwater--based fracturing, its technology needs to be irnpmved.
