摘要
本文合成一种新型稀土热稳定剂蓖麻油酸镧,并通过红外光谱分析,确定产物的结构特征。通过刚果红法、流变仪法和TG分析对其在PVC中的热稳定性能进行研究,加入蓖麻油酸镧后PVC热稳定性明显提高,其起始分解温度、最快分解温度显著增加。结果表明蓖麻油酸镧对PVC显示出了较好的热稳定性,且热稳定性在一定范围内随着蓖麻油酸镧用量的增大而增大。
The rheological properties of polymer solution in porous media were studied by using poly-mer for polymer flooding in jinzhou 9-3 and suizhong 36-1 of bohai oilfield as experimental samples.The experimental results showed that the polymer solution was degraded seriously after core shear,and the injection rate of the polymer solution after pre-degradation had little effect on its viscosity.At the same time,it can be seen that although the viscosity of the fluid changes before and after shear,the static shear force caused by the fluid’s inherent viscosity is still obvious and cannot be ignored at the moment of starting.This also leads us to consider the starting pressure of the fluid as caused by the static shear force of the fluid itself.
