摘要:
聚合微球深部调剖是一种改善油藏非均质性的有效方法,而常规聚丙烯酰胺微球耐温性、耐剪切性差,限制了微球适用范围。针对这一问题,文中以苯乙烯、二乙烯苯、丙烯酰胺为单体,失水山梨醇单油酸酯(Span80)、脂肪醇聚氧乙烯醚硫酸钠(AES)为乳化剂,采用调整表面活性剂加量控制微球粒径大小,通过乳液法制备了微米与亚微米2种不同粒径级别的微球。结果表明:微米尺寸微球表面富含丙烯酰胺链段,而亚微米尺寸微球具有核壳非均质结构,并且微球的壳以交联的丙烯酰胺链段为主;热重分析显示这两种微球具有良好的耐温性能,耐温可达300 ℃以上,耐温性能明显优于传统聚丙烯酰胺微球;研究剪切速率与剪切时间对微球粒径的影响可知这两种微球具有显著抗剪切能力。
Abstract:
Deep profile control of polymer microspheres is an effective method to improve reservoir heterogeneity. However, the poor temperature and shear resistance of traditional polyacrylamide microspheres limit the application range of reservoirs. To solve this problem, microspheres with two particle sizes of micron and submicron were synthesized through emulsion copolymerization process, using acrylamide, styrene and divinyl benzene as precursors, Span80 and fatty alcohol polyoxyethylene ether sodium sulfate (AES) as the emulsifier. Moreover, the particle size of microspheres can be controlled by adjusting the amount of surfactant. Results show that the surface of micrometer size microsphere is rich in acrylamide chains, while submicrometer size microsphere has heterogeneous core-shell structure, and the shell of the microspheres is mainly cross-linked acrylamide chains. Thermogravimetric analysis shows that these microspheres have good temperature resistance, which can reach more than 300 ℃, and its temperature resistance is significantly better than that of traditional polyacrylamide microspheres. By studying the influences of shear rate and shear time on the particle size of microspheres, it can be known that these microspheres have prominent anti-shearing.
