硼交联氮气泡沫压裂液对流换热特性研究

Convective Heat Transfer of Borate - crosslinked Nitrogen Foam Fracturing Fluid

摘要: 在大型超高压(30MPa)泡沫压裂液实验回路上，对实际施工条件下表现为非牛顿流体性质的伴氮压裂液的两相管流对流传热特性进行了研究，得出了压力、温度、泡沫质量和流量对氮气泡沫压裂液对流传热特性的影响规律，并提出了用于计算施工条件下氮气泡沫压裂液的对流换热系数关联式。实验表明：泡沫压裂液的平均Nu数主要取决于温度、泡沫质量和流量，压力的影响较小，压力对它的影响在不同泡沫质量和温度时有不同的趋势。
