摘　　要：针对永北砂砾岩油藏储层水力压裂改造难点,开展了油层保护、砂砾岩岩石力学特征、人工裂缝扩展规律、缝高控制及暂堵降滤等项技术的研究,形成了一套行之有效的致密砂砾岩油藏储层水力压裂改造技术。该技术现场应用36口井,有效率94.4%,压裂效果显著。In view of the hydraulic fracturing difficulties in Yongbei glutenite reservoir,the research covering on reservoir protection,sand conglomerate rock mechanics characteristics,extension regularity of artificial fracture,high seam control and temporary plugging fluid was carried out and then a set of effective density glutenite reservoir hydraulic fracturing technology was formed.The technology was applied in 36 wells,with effectiveness rate of 94.4% and achieved remarkable fracturing effect.
