摘　　要：通过对储集层改造技术发展历史的总结,明确了国内外储集层改造技术的新进展,总结出国内外储集层改造技术的差距,指出未来面临的技术难点及发展方向。中国与国外储集层改造技术的差距主要表现在储集层改造裂缝扩展机理、软件研发、压裂车装备、工具的耐温耐压性、支撑剂替代、大数据信息化数据库等6个方面;未来面临技术难点主要有地质与工程一体化的深度融合不够、水平井体积改造多裂缝的扩展形态及影响因素不清楚、降本空间小环保压力大、新技术缺乏室内实验及现场试验装备、压裂液体系关键技术欠成熟、工厂化压裂设备功效低等。在此基础上,结合中国储集层改造技术发展现状,提出了6个方面的建议:①做好非常规储集层改造机理研究;②加快地质-工程一体化软件研发;③促进提高采收率改造工艺升级;④开展低成本多功能压裂液配方实验;⑤尽快完成高效压裂装备配备;⑥全面建设储集层改造大数据、信息化平台及远程决策系统。Through reviewing the development history of reservoir fracturing technology,this paper demonstrated the latest research progress at home and abroad and summarized six technical gaps between China and the world,that is fracture propagation mechanism,fracturing software development,fracturing vehicle equipment,downhole tools temperature and pressure resistance,proppant replacement and big data information database.The technical difficulties include lack of geological-engineering deep integration,unclear factors on horizontal well multi-fracture propagation,difficulty in reducing construction costs,environment protection pressure,lack of new experimental and field test equipment,immature techniques for fracturing fluid,and low efficacy of factorized fracturing equipment.We proposed six suggestions on China’s reservoir hydraulic fracturing technology:(1)strengthen mechanism study of unconventional reservoir hydraulic fracturing;(2)accelerate the development of geological-engineering integration software;(3)promote the upgrading of EOR fracturing techniques;(4)carry out low-cost multi-functional fracturing fluid formula experiment;(5)complete high-efficiency fracturing equipment;(6)build big database,informational and remote decision-making system of hydraulic fracturing.
