管线材质对聚丙烯酰胺驱油剂黏损率的影响

Effect of Pipe Material on Viscosity Loss of Polyacrylamide Displacing Agent

本文研究了五种不同材质的管材对不同浓度的聚丙烯酰胺驱油剂黏损率的影响规律。实验结果表明,20#无缝钢管和防腐涂料油管对聚丙烯酰胺驱油剂黏损率的影响较大,黏损率能分别达到60%和10%,而玻璃纤维管线管、柔性复合高压输送管和0Cr18Ni9不锈钢管对聚丙烯酰胺驱油剂黏损率的影响很小,黏损率不超过3%。随着聚丙烯酰胺驱油剂浓度的升高,驱油剂黏度增大,管线材质对驱油剂黏损率的影响程度有减小的趋势。

The effect of five different kinds of pipes on viscocisy loss of polyacrylamide displacing agent with the concentration was studied in this paper. The results showed that the seamless steel pipe of 20# and the pipe with corrosion protective coating had greater influence on the viscosity loss of polyacrylamide displacing agent, and the viscosity loss rate could reach 60% and 10%, respectively. While GFRP pipe, flexible composite pipe for high pressure and 0Crl 8Ni9 stainless steel pipe had smaller influence on the viscosity loss, and the viscosity loss rate was less than 3%. With the higher concentration of polyacrylamide, the viscosity increased and the effect of pipe material on viscosity and the viscosity loss rate tended to be smaller.
