摘要
聚/表二元驱油已成为降低油水界面张力、提高原油采收率的重要技术。为进一步研究常用聚合物聚丙烯酰胺(HPAM)与非离子表面活性剂复配体系的驱油能力,在模拟新疆M区油藏环境下,利用TX-500型旋转滴界面张力仪等对HPAM与不同非离子表面活性剂复配体系的界面活性进行研究,并探究矿化度对其性能的影响,进而寻找最佳复配体系。结果表明:最佳二元复配体系HPAM浓度为0.10%,辛基酚聚氧乙烯醚10(OP-10)浓度为0.50%,复配比例为1∶6;HPAM与OP-10之间存在一定的协同效应,与单一OP-10及其他不同复配体系相比,此种复配体系能更有效地降低油水界面张力,同时具有较好的抗盐性。研究对推动和促进聚/表二元驱技术具有借鉴和参考作用。
Poly/surface binary oil repellency has become an important technology to reduce oil-water interfacial tension and improve crude oil recovery. In order to further study the oil repelling ability of commonly used polymer polyacrylamide(HPAM)and nonionic surfactant compounding system,this paper investigated the interfacial activity of HPAM and different nonionic surfactant compounding system under the simulated reservoir environment of Xinjiang M area,and explored the effect of mineralization degree on its performance,and then found the best compounding system. Results showed that the best binary compounding system was 0.1%HPAM,0.50% octylphenol ethoxylate 10(OP-10)and the ratio of HPAM to OP-10 was 1∶6. There was a certain synergistic effect between HPAM and OP-10,and compared with single OP-10 and other different compounding systems,this compounding system could reduce the oil-water interfacial tension more effectively and had better salt resistance. The present study was carried out to promote and facilitate the development of poly/OP-10. This study is useful for promoting and facilitating the poly/table binary drive technology.
