|
摘要
本文针对聚/表二元体系的性能展开分析,主要研究了聚/表二元体系的注入性能以及驱油效果。聚合物选用部分水解的聚丙烯酰胺干粉,表面活性剂选用重烷基苯磺酸盐,岩心选用人造均质块状岩心(Φ30×4.5×4.5cm),进行渗流实验,比较和分析不同渗透率以及不同聚合物浓度对阻力系数与残余阻力系数的影响,以此来判断聚/表二元体系在岩心的注入能力;然后进行驱油实验,比较和分析聚/表二元体系中组分浓度对驱油效果的影响以及聚/表二元体系与纯聚合物溶液的驱油效果的差异。
This paper analyzes the performance of polymer/surfactant binary system, and mainly studies the injection performance and oil displacement effect of polymer/surfactant binary system. The polymer is selected from partially hydrolyzed polyacrylamide dry powder, the surfactant is selected from heavy alkylbenzene sulfonate, and the core is made of artificial homogeneous massive core(Φ30×4.5×4.5 cm)for percolation experiments to compare and analyze different permeability. And the influence of different polymer concentration on the drag coefficient and the residual drag coefficient, in order to judge the injection ability of the polymer/surfactant binary system in the core; then carry out the oil displacement experiment, compare and analyze the poly/table binary system The effect of component concentration on the oil displacement effect and the difference in oil displacement between the poly-mer/surfactant binary system and the pure polymer solution.
