摘要
针对子北采油厂涧峪岔油田长2储层压裂改造压裂缝高延伸连通底水,使油井水淹无法正常生产,压裂成功率低的问题,文章在国内外控缝高压裂技术分析的基础上,根据涧峪岔长2储层特点,研究了适合该区压裂缝高控制的施工参数和控缝高延伸的添加剂KF-1压裂技术,并在油田113口井推广应用,有效率由原来的42%提高到79.6%,平均单井日增油0.43 t,取得了良好的经济效益和社会效益。
According to the low fracturing success ratio caused by extended fracturing fracture connectivity bottom water so that the well was flooded in Chang 2 reservoir fracturing of Jianyucha Oilfield,on the basis of analyzing fracture height control technique at home and abroad and Chang 2 reservoir characteristics,the construction parameters of fracturing fracture height control and the additive KF-1 of control fracturing height extension suited for Chang 2 reservoir were studied. Through test in 113 wells,the fracturing success rate was enhanced from 42% to 79. 6% when the optimized construction parameters and KF-1 fracture height control fracturing technology were used,and good economic and social benefits were achieved.
