摘    要:针对沙四段低孔、特低渗储层存在层多、层薄、微裂缝发育等特点,从分析该区块压裂改造难点入手,找出了影响压裂效果的关键因素。针对性提出了压裂液体系优化、综合降滤技术、综合控缝高技术和压裂测试技术,在高89块实现了区块大型压裂改造。现场应用证明,新投产井压裂后均自喷生产,稳产期长,增产效果显著。

关 键 词:低渗透  薄互储层  大型压裂  滤失控制  缝高控制

Abstract:In view of the Zhenglizhuang oilfield Gao 89 blocks Sha IV interval,the presence of more and thinner layers and much of microfracture in this low porosity and ultra-low permeability reservoir.With the analysis of fracturing difficulties in the block to find out the key factors that affect the fracturing effect,presents pertinent techniques such as fracturing fluid system optimization,integrated fluid loss control,integrated crack height control and fracturing test.Large-scale fracturing is performed in Zhen...
Keywords:ultra-low permeable laminated layers reservoir large-scale fracturing techno logy fluid loss control crack height control
