摘要： 压裂液的流变性是影响其压裂效果的重要因素之一。针对胜利油田滨6 6 1块研制的瓜胶与交联剂 F Y C - 1 6 0形成的压裂液体系GR J - 1 1, 研究其流变性、 耐温性和抗剪切性, 并利用扫描电镜观测了其微观结构。结果 表明, 此压裂液体系具有良好的增黏能力和抗剪切效果, 1 7 0s -1、 剪切4 0m i n后, 体系黏度仍在9 0mP a·s左右, 且 内部形成了稳定的三维交联网络结构。对此压裂液在滨6 6 1块沙四段1 2口井进行了整体压裂投产, 平均每口井日 产油5. 5 3t , 平均含水率为3 9. 7 4%, 压裂后单井获得较高产能, 满足于地层压裂的要求。

Abstract: The rheology of fracturing fluid is one of the important factors that influence the fracturing effect. The rheology, heat resistance and shear resistance of fracturing fluid (GRJ11)were studied which was consisted with guar gum and crosslinking agent(FYC160) in Shengli oilfield. Its microstructure was observed by scanning electron microscopy (SEM). The results of experimental tests showed that, the fracturing fluid system had higher property of viscosifying ability, shear resistance and more perfect threedimensional crosslinked network structure. The viscosity of the fracturing fluid could keep about 90 mPa•s after shearing at 170 s-1 for 40 min．The guar gum fracturing fluid system was applied to the field successfully for 12 oil wells，and the average oil production was 5.53 t/d and the average water cut was 39.74% after dealing with 12 wells. The GRJ11 system could match the need of the well with the low reservoir permeability of Es4 of Bin 661 black．
