摘　　要：针对牛东火山岩储层特点,在裂缝方位和油藏孔洞预测的基础上,实施大排量、中高砂比、造长缝的技术路线,以提高水力裂缝沟通储层裂缝、溶孔、溶洞的概率,形成高导流有效支撑裂缝,并通过采用压裂液体系优化技术、多段塞降阻降滤技术、液氮助排技术、快速破胶技术、深穿透主缝延伸技术及工艺参数优化技术的应用,使三塘湖火山岩油藏的压裂改造取得了突破。To characteristics of Niudong volcanic rock reservoir,such as poor physical property,high heterogeneity,rich natural fracture and strong reservoir sensitivity so on,basing on predicting fracture azimuth and reservoir cavern,tech is carried by conducting great discharge capacity,middle to high sand ratio,long fracture being built is carried out to increase probability of hydraulic fracture linking up reservoir fracture,pore and cave to form strong flowing and effective propped fracture,and by using tech of fracture fluid system optimizing,more plug friction and filtrate reducing,liquid nitrogen helping discharge,high speed gel breaking,deep penetration main fracture extending and technology parameter optimizing,fracturing gets breakthrough in volcanic rock pool of Santang lake.
