摘要
为解决室内压裂液摩阻测试装置尺寸小、管流速度低、与现场真实流动情况差异较大等问题,应用大型现场实验模拟方法,采用压裂泵车作为动力来源,实现超高速流动下的压裂液摩阻性能测试,共计测试了16组压裂液样品.结果表明,不同种类聚合物配制的压裂液间摩阻性能存在明显差异;低黏和中黏压裂液的减阻率随流速增加均呈线性减小、线性增大、先增大后减小和先减小后增大4种趋势.实验装置采用多种管径和多种长度的管路系统,实验流速最高可达100 m/s,是目前国内已知的流速最高的压裂液流动测试实验装置,满足未来现场大排量施工的实验需求,实验结果对压裂液的现场应用具有重要指导意义.
In order to solve problems with conventional in-house fracturing fluid friction test device,such as small size,low pipe flow velocity,and large difference from the real flow situation on site,we use a large-scale field experimental simulation method and the fracturing pump truck as the power source to realize the friction resistance test of fracturing fluid under ultra-high-speed flow,and test a total of 16 groups of fracturing fluid samples.The results show that the friction properties of fracturing fluids prepared with different kinds of polymers are obviously different.The drag reduction rate of low-viscosity fracturing fluid and medium viscosity fracturing fluid show 4 kinds of trend with the increase of flow rate:decreasing linearly,increasing linearly,increasing first and then decreasing,and decreasing first and then increasing.The experimental device adopts a pipeline system with multiple pipe diameters and lengths,and the experimental flow rate can reach up to 100 m/s.It is currently the highest flow rate fracturing fluid flow testing experimental device known in China,which can meet the experimental requirements of future on-site large displacement construction.The experimental results have important guiding significance for the field application of fracturing fluid.
